hsa-mir-203b: Hsa-mir-203b is a microRNA that has been implicated in various aspects of melanoma oncogenesis. It has been found that exo-HOTAIR promotes cell proliferation, migration, and invasion by sequestering hsa-mir-203b [PMC7279016]. In a study identifying critical genomic features contributing to melanoma oncogenesis, hsa-mir-203b was identified as one of the potential genes and microRNAs involved [PMC8450182]. Hsa-mir-203b, along with hsa-mir-205, has also been shown to be able to classify metastatic and primary tumor samples with high accuracy [PMC6823463]. Additionally, hsa-mir-203b has been identified as one of the critical miRNAs in melanoma [PMC7505395]. The expression patterns of hsa-mir-203b have been verified in test data from GSE119794 data [PMC7505395]. Furthermore, Oasis 2 identified hsa-mir-203b as a predicted novel differentially expressed miRNA in melanoma [PMC5813365]. In summary, hsa-mir-203b is a microRNA that plays a role in promoting cell proliferation, migration, and invasion in melanoma. It is also involved in the classification of metastatic and primary tumor samples. The expression patterns of hsa-mir-203b have been verified and it has been identified as a critical miRNA in melanoma oncogenesis. Additionally, it has been predicted as differentially expressed in melanoma by Oasis 2.
