B6-hTFRC/htau
Product ID:
I001209
Strain:
C57BL/6Cya
Status:
Description:
The Transferrin receptor (TFRC) gene encodes Transferrin Receptor 1 (TFR1), a protein that is expressed at low levels in most normal cells but shows increased expression in highly proliferative cells, such as basal epidermal cells, intestinal epithelium, and certain activated immune cells. Brain capillary endothelial cells, which constitute the blood-brain barrier (BBB), also express this receptor at high levels [1]. TFR1 plays a critical role in maintaining iron metabolism and homeostasis by facilitating receptor-mediated endocytosis of iron-bound transferrin (Tf) via Tf cycling, thereby promoting iron uptake [2]. Cellular iron deficiency can lead to apoptosis, while cellular transformation requires substantial iron to sustain proliferation, with iron overload contributing to tumor progression. The high expression of TFR1 in many tumors makes it a potential tumor marker, offering a target for therapies to inhibit tumor growth and metastasis [1]. Moreover, TFR1 is implicated in anemia and iron metabolism disorders. Studies have shown that elevated TFR1 expression in cardiomyocytes is associated with exacerbated inflammation in myocarditis patients [3].
The tau protein, a microtubule-associated protein encoded by MAPT, is primarily localized to neuronal axons and plays a critical role in microtubule stability and assembly. By binding to microtubules, the tau protein helps to maintain neuronal cell shape. Mutations in MAPT can promote tau aggregation, leading to pathological tau protein accumulation and death of glutamatergic cortical neurons [4]. Additionally, certain MAPT mutations can affect pre-mRNA exon splicing, altering the ratio of 3R to 4R tau protein isoforms and increasing the relative production of 4R-tau protein, which is more prone to fibril formation [5].
The B6-hTFRC/htau mice are a model expressing human TFRC protein and tau protein, generated by crossing B6-hTFRC(CDS) mice (Catalog No.: C001584) with B6-htau mice (Catalog No.: C001410). These mice can be used for research on neurodegenerative diseases and iron metabolism disorders, as well as for the development and preclinical evaluation of TFRC/MAPT-targeted therapeutic agents.

Moreover, TFR1 is implicated in anemia and iron metabolism disorders. Studies have shown that elevated TFR1 expression in cardiomyocytes is associated with exacerbated inflammation in myocarditis patients [3]. As a target for antibody-mediated cancer therapy, TFR1 can be leveraged through two approaches: one involves the use of antibodies conjugated to anti-cancer drugs, which are indirectly internalized via receptor-mediated endocytosis; the other employs antibodies that directly disrupt receptor function or induce Fc effector functions such as antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), or complement-dependent cytotoxicity (CDC). Various clinical drugs targeting TFR1 are currently under development, including antisense oligonucleotides (ASOs), antibody-drug conjugates (ADCs), and antibody-oligonucleotide conjugates, applicable to diseases such as cancer, anemia, and neurodegenerative disorders. Research indicates that enhancing antibody transport across the blood-brain barrier via TFR1, by forming specific bispecific antibodies with anti-β-amyloid antibodies, can improve therapeutic outcomes in Alzheimer's patients [4-5]. As research progresses, TFR1 is expected to become an effective clinical target for multiple diseases and a synergistic target for drug delivery across the blood-brain barrier (BBB).

B6-hTROP2 (hTACSTD2)
Product ID:
C001718
Strain:
C57BL/6NCya
Status:
Description:
Tumor-Associated Calcium Signal Transducer 2, encoded by the TACSTD2 gene, is a prominent type I transmembrane glycoprotein critically involved in mediating diverse cellular processes [1]. Acting primarily as a cell surface receptor, TROP2 transduces extracellular signals to initiate intracellular calcium release, thereby influencing key cellular behaviors including proliferation, adhesion, migration, and differentiation. While its expression is notably high during embryonic development, particularly in fetal tissues and trophoblasts, and maintained at lower levels in some normal adult epithelial lineages, aberrant and significant upregulation of TROP2 is a hallmark feature across a wide spectrum of human carcinomas [2]. This dysregulated expression contributes substantially to tumor initiation, progression, and metastasis by modulating various signaling pathways [3]. Beyond its role in oncogenesis, germline mutations in TACSTD2 are identified as the underlying cause of the rare autosomal recessive disorder, gelatinous drop-like corneal dystrophy [4]. The distinct expression profile of TROP2, with its high levels in numerous solid tumors contrasted by limited expression in most healthy adult tissues, positions it as a compelling and clinically relevant target for developing targeted therapies, notably antibody-drug conjugates, aimed at treating TROP2-expressing cancers [3].
The B6-hTROP2 (hTACSTD2) mouse is a humanized model constructed by replacing the signal peptide and extracellular domain of the mouse Tacstd2 with the corresponding signal peptide and extracellular domain from the human TACSTD2 gene. The B6-hTROP2 (hTACSTD2) mice can be used for studies on pathogenesis of various cancers, as well as for TACSTD2-targeted drug development.

huCD40LG
Product ID:
C001720
Strain:
C57BL/6NCya
Status:
Description:
The CD40LG gene is located on the X chromosome (Xq26.3) and encodes CD40 ligand (CD40L, also known as CD154), a type II transmembrane protein mainly expressed on activated T cells, platelets, and some B cells. Under inflammatory conditions, monocytes, natural killer cells, mast cells, and basophils can also be induced to express CD40L [1-3]. This protein binds to CD40 on the surface of antigen-presenting cells (such as B cells and dendritic cells), mediating key immune functions including T cell-dependent B cell activation, immunoglobulin class switching, and germinal center formation [3]. The CD40/CD40L interaction also regulates thrombosis, inflammatory responses, hematopoiesis, and the tumor immune microenvironment. Abnormal regulation of CD40LG is associated with X-linked hyper-IgM syndrome (XHIGM), a primary immunodeficiency disease characterized by recurrent infections due to defective antibody production [4]. In addition, abnormal expression of CD40L is involved in diseases such as systemic lupus erythematosus and atherosclerosis through its pro-inflammatory effects [5-6]. Due to the important role of the CD40/CD40L interaction in immune activation, CD40/CD40L has been an important target for immunotherapy. In recent years, significant progress has been made in CD40/CD40L-targeted therapy. Various drugs have been developed, including agonistic/antagonistic monoclonal antibodies, cellular vaccines, adenoviral vectors, and protein antagonists, and have shown therapeutic potential in malignant tumors, autoimmune diseases, and allograft rejection [7].
The huCD40LG mice are a humanized model constructed by using gene editing technology to replace the endogenous extracellular domain of the mouse Cd40lg gene with the extracellular domain of the human CD40LG gene. This model can be used for research on the disease mechanisms and treatment methods of autoimmune diseases, cardiovascular diseases, cancers, etc., as well as for CD40LG-targeted drug development.

huIL6/hIL6RA/Apoe-KO
Product ID:
C002139
Strain:
C57BL/6Cya
Status:
Description:
Interleukin-6 (IL-6) is a cytokine that plays a crucial role in inflammation and B cell maturation. It is primarily produced and secreted into the serum at sites of acute and chronic inflammation, inducing inflammatory responses through the interleukin-6 receptor alpha (IL-6Rα). The IL6RA (IL6R, also known as CD126) gene encodes a subunit of the interleukin-6 (IL-6) receptor complex. The IL-6 receptor is a protein complex composed of the IL6RA protein and the interleukin-6 signal transducer (IL6ST/GP130/IL6-beta). This receptor subunit is shared by many other cytokines. The expression of IL-6R is primarily restricted to hepatocytes, leukocytes, and megakaryocytes. Upon binding to IL-6Rα, IL-6 interacts with two GP130 molecules to form a hexameric complex in a 2:2:2 configuration [1]. Once the IL-6 receptor complex is activated, multiple downstream events allow IL-6 to mediate its diverse effects. These include the pathways of the GTPase Ras and its effector Raf, the mitogen-activated protein kinase cascade that controls cellular proliferation and differentiation, and the pathways involving tyrosine kinases of the Jak family and transcription factors of the STAT family [2].
Apolipoprotein E (ApoE) is a lipid particle-associated polymorphic carrier protein encoded by the APOE gene. It is a core component of plasma lipoproteins, participating in the production, transport, and clearance of lipoproteins. ApoE is associated with chylomicrons, chylomicron remnants, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), and intermediate-density lipoprotein (IDL), especially showing preferential binding to HDL [3]. ApoE is the most important lipid transport protein in the body, having a profound impact on lipid metabolism. The interaction of ApoE with the low-density lipoprotein receptor (LDLR) is essential for the normal processing (catabolism) of triglyceride-rich lipoproteins [4]. In peripheral tissues, ApoE is primarily produced by the liver and macrophages and mediates cholesterol metabolism. In the central nervous system, ApoE is produced mainly by astrocytes and is the major cholesterol carrier in the brain. ApoE is essential for transporting cholesterol from astrocytes to neurons [3-6]. In addition, ApoE forms a complex with activated C1q, becoming a checkpoint inhibitor target of the classical complement pathway [7].
The huIL6/hIL6RA/Apoe-KO mouse is a combined genetically modified model generated by crossing the huIL6 mouse (Catalog No.: C001605), the hIL6RA mouse (Catalog No.: C001606), and the Apoe-KO(6J) mouse (Catalog No.: C001507). The huIL6/hIL6RA/Apoe-KO mouse can be utilized for the screening, pharmacodynamic evaluation, safety assessment, and mechanism of action studies of IL6/IL6RA-targeted therapeutics. With the Apoe knockout background, the model can also be used for research on hypercholesterolemia and atherosclerosis, providing a preclinical research tool for exploring the effects of IL6/IL6RA-targeted interventions in relevant disease settings.

huMSTN(GDF8)
Product ID:
C001636
Strain:
C57BL/6NCya
Status:
Description:
The MSTN gene, also known as growth differentiation factor 8 (GDF8), encodes myostatin, a secreted protein belonging to the transforming growth factor-β (TGF-β) superfamily [1]. MSTN is primarily expressed in skeletal muscle, with low-level expression also detected in myocardium, adipose tissue, and brain tissue. It encodes the myostatin protein, a key negative regulator of skeletal muscle development [1]. Myostatin, through autocrine and paracrine signaling, inhibits muscle cell proliferation and differentiation, thereby limiting excessive skeletal muscle growth and maintaining muscle mass homeostasis [1-4]. Thus, MSTN plays a critical role in regulating body muscle development and maintaining normal muscle mass [3]. Furthermore, myostatin is implicated in adipogenesis regulation, exerting an inhibitory effect on fat cell differentiation [2]. Mutations in MSTN are associated with myostatin-related muscle hypertrophy, characterized by significant increases in muscle volume and strength, typically without severe medical consequences [5]. Consequently, inhibitors targeting myostatin are considered potential therapeutic targets for diseases such as muscular dystrophy and sarcopenia, and have shown promise in improving metabolic syndrome [1-5].
The huMSTN(GDF8) mouse is a humanized model constructed using gene editing technology, where the mouse Mstn genomic DNA was replaced with the human MSTN genomic DNA. The murine signal peptide was preserved. This model can be used for studying the pathological mechanisms and therapeutic approaches of muscular dystrophy, sarcopenia, and metabolic syndrome, and for the development of MSTN-targeted drugs.

huTARDBP
Product ID:
C001418
Strain:
C57BL/6JCya
Status:
Description:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal progressive neurodegenerative disease characterized by the degeneration and death of motor neurons in the central nervous system. This loss of motor neurons leads to progressive muscle weakness and atrophy, ultimately culminating in the complete loss of voluntary muscle control. Consequently, ALS can induce speech, swallowing, and respiratory difficulties [1]. Critically, unlike Alzheimer's disease, ALS does not necessarily impact higher-order cognitive functions. Remarkably, patients in advanced stages of the disease can maintain clear thinking and retain their premorbid memory, personality, and intelligence. Several genes have been identified as causative factors in ALS, including SOD1, ALS2, TARDBP, and FUS. Among them, TARDBP (TAR DNA-binding protein) is a gene encoding a protein involved in diverse cellular functions, including facilitating nuclear protein import, regulating circadian rhythms, and maintaining protein stability [2]. Mutations in the TARDBP gene are linked to ALS. These mutations can lead to abnormal TDP-43 protein accumulation and its mislocalization to the cytoplasm, a key pathological hallmark of the disease [3].
TARDBP-targeted therapy is mainly based on monoclonal antibody drugs, most of which are still in the preclinical stage of development. Oligonucleotides such as ASO and gene therapy have also been reported in the literature. These drugs are mainly used for the treatment of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). TARDBP is a new and popular target for the treatment of ALS. Preclinical disease research models are mainly transgenic (TG) or point mutation (PM) mice. To advance TARDBP-targeted drug therapies, especially gene and oligonucleotide therapies, Cyagen has independently developed a mouse Tardbp gene humanized model, which replaces the mouse Tardbp gene with the human TARDBP gene through gene editing technology. It can be used to study neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal dementia. The homozygous huTARDBP mice are viable and fertile. In addition, based on the technological innovation of TurboKnockout fusion BAC recombination, Cyagen can also provide popular point mutation disease models based on this model and can provide customized services according to different point mutations to meet the needs of researchers for amyotrophic lateral sclerosis and frontotemporal dementia.

huSNCA
Product ID:
C001427
Strain:
C57BL/6NCya
Status:
Description:
Parkinson's disease (PD) is a degenerative disease of the nervous system that occurs mostly in middle-aged and elderly people and is the second most common neurodegenerative disease after Alzheimer's disease (AD). Clinical symptoms of PD are characterized by resting tremors, limb stiffness, bradykinesia, and lack of voluntary movement. The typical pathology of PD is characterized by the formation of Lewy bodies (LB) in the central nervous system (CNS). This process leads to the progressive death and loss of dopaminergic neurons, ultimately resulting in the development of Parkinson's disease. Lewy bodies are mainly composed of insoluble aggregates of abnormal α-synuclein (α-syn).
The SNCA gene, one of the key pathogenic genes in Parkinson's disease, encodes α-syn. Mutations in SNCA can cause overexpression of α-syn, which leads to the formation of Lewy bodies and ultimately PD. Therefore, the SNCA gene is considered an effective drug target for the treatment of PD [1].
Gene therapy is one of the ways to treat PD, among which the development prospects of SNCA-targeted drugs are particularly prominent. The drug pipelines targeting SNCA are widely laid out, and ASO, siRNA, and CRISPR therapies have emerged [2].
This strain is a mouse Snca gene humanized model and can be used for research on PD. The homozygous huSNCA mice are viable and fertile. Leveraging its proprietary TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields related to PD.

Lewy bodies are mainly composed of insoluble aggregates of abnormal α-synuclein (α-syn).
The SNCA gene, one of the key pathogenic genes in Parkinson's disease, encodes α-syn. Mutations in SNCA can cause overexpression of α-syn, which leads to the formation of Lewy bodies and ultimately PD. Therefore, the SNCA gene is considered an effective drug target for the treatment of PD [1].
Gene therapy is one of the ways to treat PD, among which the development prospects of SNCA-targeted drugs are particularly prominent. The drug pipelines targeting SNCA are widely laid out, and ASO, siRNA, and CRISPR therapies have emerged [2].
This strain is a mouse Snca gene humanized model and can be used for research on PD. The homozygous huSNCA mice are viable and fertile. Leveraging its proprietary TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields related to PD.
huSNCA(2)/huTFRC
Product ID:
C001873
Strain:
C57BL/6NCya
Status:
Description:
The Transferrin receptor (TFRC) gene encodes Transferrin Receptor 1 (TFR1), a protein that is expressed at low levels in most normal cells but shows increased expression in highly proliferative cells, such as basal epidermal cells, intestinal epithelium, and certain activated immune cells. Brain capillary endothelial cells, which constitute the blood-brain barrier (BBB), also express this receptor at high levels [1]. TFR1 plays a critical role in maintaining iron metabolism and homeostasis by facilitating receptor-mediated endocytosis of iron-bound transferrin (Tf) via Tf cycling, thereby promoting iron uptake [2]. Cellular iron deficiency can lead to apoptosis, while cellular transformation requires substantial iron to sustain proliferation, with iron overload contributing to tumor progression. The high expression of TFR1 in many tumors makes it a potential tumor marker, offering a target for therapies to inhibit tumor growth and metastasis [1]. Moreover, TFR1 is implicated in anemia and iron metabolism disorders. Studies have shown that elevated TFR1 expression in cardiomyocytes is associated with exacerbated inflammation in myocarditis patients [3]. Various clinical drugs targeting TFR1 are currently under development, including antisense oligonucleotides (ASOs), antibody-drug conjugates (ADCs), and antibody-oligonucleotide conjugates, applicable to diseases such as cancer, anemia, and neurodegenerative disorders. Research indicates that enhancing antibody transport across the blood-brain barrier via TFR1, by forming specific bispecific antibodies with anti-β-amyloid antibodies, can improve therapeutic outcomes in Alzheimer's patients [4-5]. As research progresses, TFR1 is expected to become an effective clinical target for multiple diseases and a synergistic target for drug delivery across the blood-brain barrier (BBB).
Parkinson's disease (PD) is a neurodegenerative disease with a high prevalence mainly in the middle-aged and elderly population. It is the second most common neurodegenerative disease after Alzheimer's disease (AD). The main clinical symptoms include resting tremors, limb stiffness, bradykinesia, loss of voluntary movement, etc. The typical pathological process of PD is the formation of Lewy bodies (LB) in the central nervous system (CNS), which results in the gradual death and loss of dopaminergic neurons, leading to the disease [6-7]. The main components of Lewy bodies are insoluble aggregates of abnormal α-synuclein (α-syn), and the SNCA gene, which encodes α-synuclein, is one of the key causative genes in Parkinson's disease. Mutations in this gene cause overexpression of α-syn, leading to the formation of Lewy bodies, ultimately leading to PD [8]. In addition, SNCA mutations are also associated with diseases such as dementia with Lewy bodies (DLB) and multiple system atrophy (MSA).
huSNCA(2)/huTFRC mice are a dual-gene humanized model generated by crossing huTFRC mice (Catalog No.: C001860) with huSNCA(2) mice (Catalog No.: C001698). This model can be used for research on neurodegenerative diseases such as Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), as well as iron metabolism disorders and tumorigenesis and development. It is also applicable for the development of TFRC/SNCA-targeted drugs.

huMSLN
Product ID:
C001856
Strain:
C57BL/6NCya
Status:
Description:
The MSLN gene encodes a preproprotein that is proteolytically processed into two distinct proteins: megakaryocyte potentiating factor (MPF) and mesothelin [1]. MPF functions as a cytokine that promotes the formation of megakaryocytes in bone marrow, while mesothelin is a glycosylphosphatidylinositol-anchored cell-surface protein that may play a role in cell adhesion. While mesothelin expression is normally low and restricted to mesothelial cells lining the pleura, peritoneum, and pericardium, it is highly overexpressed in several epithelial cancers, including malignant mesothelioma, ovarian cancer, pancreatic cancer, and certain types of lung cancer [2-3]. This high expression and its function in promoting cell proliferation and metastasis make mesothelin a significant biomarker and a target for cancer therapies [4].
The huMSLN mouse model was generated by replacing sequences from the ATG start codon to the TGA stop codon of the endogenous mouse Msln gene with the sequences from the ATG start codon to the TGA stop codon of the human MSLN gene. This model can be used to study the pathological mechanisms and therapeutic approaches for several cancers, including malignant mesothelioma, ovarian cancer, pancreatic cancer, and certain types of lung cancer, as well as for the development of MSLN-targeted drugs.
