Modulation of Spliceosomal Proteins hnRNPH1 and H2 Increases Melanoma Cell Pro-Inflammatory Signaling In Vitro.

ABSTRACT: Melanoma is the most aggressive and deadliest form of skin cancer, and the current treatments of melanoma have many limitations, which necessitate discovering new compounds and targets for melanoma. Two probes, 2155-14 and 2155-18, were identified to induce apoptotic cell death, autophagy, and immune signaling modulation through hnRNPH1/H2-dependent mechanisms. RNA sequencing following the siRNA-mediated knockdown of hnRNPH2 in melanoma cells revealed an enrichment of immune-related signaling pathways. The present study investigated the effect of genetic and pharmacologic downregulation of hnRNPH1/H2 on melanoma immunogenicity in vitro. Our results indicated that treating melanoma cell lines with 2155-14 and 2155-18 led to hnRNPH1/H2 downregulation, whereas hnRNPH2 siRNA treatment led to o
