AbstractRecently studies found that APEX1 was abnormally expressed in melanoma, indicating that it might be involved in the development of melanoma. However, the underlying mechanism and the interaction between APEX1 and LINC00470 in melanoma are not clear. Therefore, we aimed to investigate the role of LINC00470 in the development of melanoma in this work. We discovered that LINC00470 was overexpressed in melanoma tissues and cells compared with the adjacent normal tissues and cells by qPCR. The overexpression of LINC00470 promoted the proliferation and migration of melanoma cells. The functional investigation demonstrated that LINC00470 activated the transcription factor, ZNF131, to regulate the APEX1 expression, which finally promoted cell proliferation and migration. In contrast, knockdown of LINC00470 could significantly inhibit the melanoma cell proliferation and migration, and suppress the growth of tumor in vivo. Overexpression of APEX1 could reverse the impact of the silence of LINC00470 in melanoma cells. In summary, our studies revealed that LINC00470 promoted melanoma proliferation and migration by enhancing the expression of APEX1, which indicated that LINC00470 might be a therapeutic target for the treatment of melanoma.

Cigarette smoking is associated with an increased risk of melanoma metastasis. Smokers show higher PD-L1 expression and better responses to PD-1/PD-L1 inhibitors than nonsmokers. Here, we investigate whether nicotine, a primary constituent of tobacco, induces PD-L1 expression and promotes melanoma cell proliferation and migration, which is mediated by the α9 nicotinic acetylcholine receptor (α9-nAChR). α9-nAChR overexpression in melanoma using melanoma cell lines, human melanoma tissues, and assessment of publicly available databases. α9-nAChR expression was significantly correlated with PD-L1 expression, clinical stage, lymph node status, and overall survival (OS). Overexpressing or knocking down α9-nAChR in melanoma cells up- or downregulated PD-L1 expression, respectively, and affected melanoma cell proliferation and migration. Nicotine-induced α9-nAChR activity promoted melanoma cell proliferation through stimulation of the α9-nAChR-mediated AKT and ERK signaling pathways. In addition, nicotine-induced α9-nAchR activity promoted melanoma cell migration via activation of epithelial-mesenchymal transition (EMT). Moreover, PD-L1 expression was upregulated in melanoma cells after nicotine treatment via the transcription factor STAT3 binding to the PD-L1 promoter. These results highlight that nicotine-induced α9-nAChR activity promotes melanoma cell proliferation, migration, and PD-L1 upregulation. This study may reveal important insights into the mechanisms underlying nicotine-induced melanoma growth and metastasis through α9-nAChR-mediated carcinogenic signals and PD-L1 expression.

Abstract Objectives Melanoma, the 5th most common cancer in the US, is the most aggressive form of skin cancer. Excess adiposity is associated with an increased risk of melanoma in males, and a high-fat diet promotes melanoma tumor growth in mice. Our group found that lipid droplet (LD) content increases with melanoma cell aggressiveness and that fatty acid uptake inhibition reduces cell proliferation and migration; however, the function of these lipids in melanoma is unknown. Since lipids can be used to produce energy by fatty acid oxidation (FAO), we sought to determine whether melanoma cells were using FAO to maintain aggressiveness. Methods Gene expression microarray was used to identify differences in gene expression, which was confirmed by RT-qPCR. WM983A, WM983B, 1205Lu and A375 human melanoma cells were treated with 5 µM Etomoxir and cell proliferation, migration, and respiration were quantified using the Quant-iT™ PicoGreen™ dsDNA Assay Kit, Boyden Chamber transwell migration, and Seahorse XFe96 Flux Analyzer, respectively. Results The most significantly altered genes expressed between four invasive, lipid-rich and four non-invasive, lipid-poor melanoma cells pertained to fatty acid metabolism. Carnitine palmitoyltransferase 1A (CPT1a), the rate limiting enzyme in mitochondrial FAO (mFAO), mRNA was increased in lipid-rich cells compared to the lipid-poor cells (p < 0.05, n = 6–7), indicating that melanoma cells may use LD lipids for mFAO. To determine the importance of mFAO to melanoma cells, we inhibited mFAO with etomoxir, an irreversible CPT1 inhibitor. Treatment of lipid-rich 1205Lu and A375 cells or lipid-poor WM983A and WM983B cells with etomoxir for 4 days had no effect on cell proliferation. Extracellular flux analysis of cells with or without etomoxir showed no difference in ATP production, indicating that melanoma cells do not use mFAO to generate energy under normal conditions. In motile cells, etomoxir reduced lipid-rich A375 cell migration by 8.8% (p = 0.05, n = 2). Conclusions Lipids play a role in melanoma aggressiveness; however, our results indicate that mFAO of lipids is not vital to melanoma cell proliferation or migration. Further studies are required to understand the implication of excess adiposity and circulating lipids in melanoma development and progression. Funding Sources Institutional Department Fund
