hsa-mir-185: Hsa-mir-185 is a microRNA gene that has been implicated in various cellular processes and diseases, including autism and cancer [PMC3965395]. Studies have shown that hsa-mir-185 is not associated with variations in the TrkB-T1 3′UTR sequence or the region encoding its microRNA, suggesting other regulatory mechanisms may influence its expression [PMC3382618]. In cellular experiments, hsa-mir-185 transfection has been observed to increase the percentage of cells in the G1 phase of the cell cycle, indicating a potential role in cell cycle regulation [PMC2722734]. Furthermore, hsa-mir-185 has been significantly associated with mitochondria in HEK293 cells, which may have implications for cellular energy dynamics and apoptosis [PMC3439422]. In breast cancer, hsa-mir-185 is part of a regulatory profile for Smad7 expression [PMC6310970], while its high expression has been correlated with metastasis and poor clinical outcomes in colorectal cancer [PMC6003936]. Additionally, hsa-mir-185 has been used as a mimic in transfection experiments to study its effects on cellular functions [PMC9064001], and it is considered as part of a prognostic signature comprising multiple plasma miRNAs for disease outcomes [PMC5981448]. Its role as a tumor suppressor miRNA is highlighted by its downregulation alongside other tumor suppressor miRNAs such as hsa-let-7i and hsa-miR-34a [PMC5511817], indicating its potential utility as an epigenetic biomarker for cancer therapy prediction and early detection.
