Overview of Gene Research
Hnrnpr, a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family, is an RNA-binding protein primarily functioning in the spliceosome C complex. It is involved in multiple biological processes such as alternative splicing, mRNA stability regulation, and gene expression control, which are crucial for normal development and cellular functions [3,5].
Knockdown of Hnrnpr in two types of mouse models with gastric cancer tumors decreased tumor aggressiveness and metastasis. Mechanistically, Hnrnpr promotes gastric cancer cell proliferation, migration, and invasion by stabilizing the mRNA levels of CCNB1 and CENPF [1]. In hepatocellular carcinoma, Hnrnpr binds to UPF3B pre-mRNA to generate an oncogenic splice variant UPF3B-S, which promotes cancer cell invasion and metastasis [2]. In neuroblastoma, Hnrnpr binds to and stabilizes ASCL1 mRNA in an m6A-dependent manner, promoting neuroblastoma progression [4].
In conclusion, Hnrnpr plays essential roles in various biological processes and disease conditions. Mouse models with Hnrnpr knockdown have revealed its significant impact on cancer-related processes, including proliferation, migration, and invasion in gastric, liver, and neuroblastoma cancers, highlighting its potential as a therapeutic target in these disease areas.
