hsa-mir-337: Hsa-mir-337 is a human miRNA locus located at chromosome 14q32.2 [PMC3377607]. It has been associated with various cancers, including head and neck squamous cell carcinoma (HNSCC) [PMC5008307]. In HNSCC, a negative correlation between EGR1 and hsa-mir-337 is related to higher survival rates, while a positive correlation is related to poor survival rates [PMC3836703]. Hsa-mir-337 is part of a six microRNA signature (including hsa-let-7c, hsa-miR-125b-2, hsa-miR-129-1, hsa-miR-654, and hsa-miR-99a) that has been validated as an independent predictor for HNSCC patient survival [PMC5008307]. It has also been shown to play a role in reducing gastric cancer cell invasion capacity and has been associated with lymph node metastasis in gastric cancer [PMC5123339]. In bladder cancer (BLCA), a three miRNA signature consisting of hsa-mir-337, hsa-mir-3913-2, and hsa-mir-497 has been identified as an independent predictor for prognosis [PMC5739658]. Furthermore, in prostate cancer and HNSCC patients, hsa-mir 99a and 137 have also been identified as potential prognostic biomarkers [PMC6409312] [PMC9463596]. Overall, the role of hsa-mir 337 in various cancers suggests its potential as a diagnostic tool and therapeutic target.
