Overview of Gene Research
CALCRL, short for calcitonin receptor-like receptor, is a G-protein-coupled neuropeptide receptor. It is involved in various biological processes, and its associated pathways include cyclic AMP (cAMP) signaling pathway, which is activated when it forms a receptor complex with RAMP1 in response to ligands like calcitonin gene-related peptide (CGRP) [1,3,5,6]. It is of great biological importance in processes such as immune response, hematopoiesis, and drug-tolerance in cancer cells. Genetic models, like KO or CKO mouse models, are valuable for studying its functions.
In the spleen, nociceptors release CGRP which acts on B cells through the CALCRL-RAMP1 complex via the cAMP pathway, promoting germinal center response and humoral immunity [1]. In acute myeloid leukemia (AML), CALCRL is expressed in relapse-initiating drug-tolerant cells. Knockdown of CALCRL impairs leukemic growth, decreases the frequency of leukemia-initiating cells, and sensitizes cells to cytarabine [2]. In tendon-bone healing, overexpression of Calcrl in mice improves osteogenic differentiation, type H vessel and nerve fiber intensity at the tendon-bone interface, as well as gait and biomechanical performance [3]. In AML/ETO + AML patients, lower CALCRL expression is associated with longer survival, and its expression decreases after chemotherapy-induced remission [4]. In AML cells, overexpression of CALCRL confers resistance to daunorubicin through up-regulation of the XRCC5/TYK2/JAK1 pathway [7]. In glioma, interfering with CALCRL expression in U87 cells (a glioma cell line) inhibits proliferation, promotes apoptosis, and is related to prognosis, especially in low-grade gliomas [8].
In conclusion, CALCRL plays essential roles in multiple biological processes. Through model-based research, its significance in immune regulation, cancer drug-resistance, and tissue repair has been revealed. In particular, in diseases like AML and glioma, studies using KO/CKO mouse models could potentially provide insights into novel therapeutic strategies targeting CALCRL.
