Long Noncoding RNA PICSAR Promotes Growth of Cutaneous Squamous Cell Carcinoma by Regulating ERK1/2 Activity
Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, and its incidence is increasing globally. Long noncoding RNAs (lncRNA) are involved in various biological processes, and their role in cancer progression is emerging. Whole transcriptome analysis of cSCC cells (n = 8) and normal human epidermal keratinocytes (n = 4) revealed overexpression of long intergenic ncRNA (LINC00162) in cSCC cells. The expression of LINC00162 in cSCC cells was upregulated by inhibition of the p38α and p38δ mitogen-activated protein kinases.The Long Noncoding RNA SPRIGHTLY Regulates Cell Proliferation in Primary Human Melanocytes
The long noncoding RNA SPRIGHTLY (formerly SPRY4-IT1), which lies within the intronic region of the SPRY4 gene, is up-regulated in human melanoma cells compared to melanocytes. SPRIGHTLY regulates a number of cancer hallmarks, including proliferation, motility, and apoptosis. To better understand its oncogenic role, SPRIGHTLY was stably transfected into human melanocytes, which resulted in increased cellular proliferation, colony formation, invasion, and development of a multinucleated dendritic-like phenotype.
