Accumulating evidence showed that aberrant miRNAs expression was involved in initiation and progression of melanoma. However, the investigation of different miRNAs in melanoma remain attractive. In this research, we demonstrated that miR-610 expression was decreased in melanoma tissues and cell lines. The clinical data showed that the reduced miR-610 expression was obviously associated with adverse prognostic characteristics. Furthermore, our results suggested that miR-610 had a function of prognostic indicator for 5-year predicted-survival of melanoma patients. The ectopic overexpression of miR-610 suppressed cell proliferation, cell cycle progression and promoted apoptosis while miR-610 knockdown reversed the effect in vitro and in vivo. Additionally, miR-610 could modulate LRP6 by directly interacting to its 3’-UTR. In clinical samples of melanoma, miR-610 inversely correlated with LRP6. The biological function of miR-610 on melanoma cells was abrogated by alternation of LRP6 expression. In summary, our research indexed that miR-610 had a function of tumor suppressor in regulating the proliferation, cell cycle and apoptosis of melanoma via targeting LRP6. Hence, it may represent a novel potential therapeutic target and prognostic marker for melanoma.

Long intergenic noncoding RNA 00511 (LINC00511) predicts poor prognosis in various malignancies and functions as an oncogene in distinct malignant tumors. The role of LINC00511 in melanoma progression was assessed. In our research, expression of LINC00511 in melanoma cells was detected by quantitative reverse transcription PCR. Colony formation and CCK8 assays were used to detect cell proliferation. Cell metastasis was evaluated by transwell and wound healing assays. Downstream target of LINC00511 was investigated by luciferase activity assay. As a results, LINC00511 was elevated in melanoma cells and tissues. Loss of LINC00511 decreased cell viability, reduced proliferation, invasion, and migration of melanoma. miR-610 was target of LINC00511, and miR-610 binds to 3′UTR of nucleobindin-2 (NUCB2). Inhibition of miR-610 attenuated LINC00511 deficiency-induced decrease of NUCB2 in melanoma cells. Loss of miR-610 weakened LINC00511 deficiency-induced decrease of cell viability, proliferation, invasion, and migration of melanoma. In conclusion, silence of LINC00511 reduced cell proliferation and metastasis of melanoma through down-regulation of miR-610-mediated NUCB2.

Dermatologic diseases are the fourth most frequent nonfatal common illness, yet they have a psychological, economical, and professional burden that is comparable to or larger than other chronic conditions. From a survey in China of 6 provinces, the overall prevalence of psoriasis with squamous cell carcinoma was 0.47%. According to the current investigation, the outburst of skin disease was not associated with gender, but mainly with the climate of the environment; that is, dry cold weather will more likely to induce psoriasis. Approximately 3% of people around the world have psoriasis, which is near the most common autoimmune skin disease in adults. By simple estimation, there are at least two hundred million psoriasis patients in the world. Therefore, it is not just a simple health problem in a country or a region but a serious global challenge. Of note, about half of the adult patients had been reported to be sick in their childhood and they mostly fell ill around 10 years old. Actinic keratosis is perhaps the most common, followed by squamous cell carcinoma and, to a lesser extent, acne vulgaris, psoriasis, and hidradenitis suppurativa, as well as dermatitis herpetiformis. 5-Fluorouracil (5-FU) 0.5 percent is used topically to treat actinic keratosis and squamous cell carcinoma with good outcomes, while it might cause significant toxicity in certain patients. Dapsone, a Valosin-containing protein, is a medication that is often used to treat inflammatory skin disorders like psoriatic arthritis, but it can occasionally cause hemolytic anemia. Furthermore, biologic medications for the treatment of moderate-to-severe psoriasis and multiple squamous cell carcinoma have proven to be successful and safe; nevertheless, a small percentage of patients do not react to biologic treatment in the long term or do not respond at all. Based on the data from the China Food and Drug Administration, the majority of chemical drugs are utilized as the topical formulations, while Chinese medicines are mainly delivered by an oral route, suggesting that the market for topical preparations of Chinese medicine to treat skin diseases like psoriasis is worth exploration. This large interindividual diversity in response could be caused by changes in genes that encode proteins implicated in the disease’s pathologic environment or the medication’s mechanism of action. Pharmacogenetics is the study of the association between genetic differences and medication response, which is valuable for identifying nonresponsive patients and those who are more likely to suffer toxicity as a result of treatment. This study highlights the pharmacogenetic recommendations for dermatology therapies that have the strongest evidence at this time, highlighting those that have been incorporated in clinical practice guides. Pharmacogenetic clinical guidelines for multiple squamous cell carcinoma and psoriasis vulgaris were found in this investigation. Here, for multiple squamous cell carcinoma trichohyalin-like 1 (TCHHL1), 5-fluorouracil (5-FU) 0.5% is recommended. Along with that dapsone, Valosin-containing protein can be recommended for treating the psoriasis vulgaris. We made some clinical trials over the two diseases, and from the result obtained, we hypothesize that the suggested drug may be a novel therapeutic target in treating the multiple squamous cell carcinoma with psoriasis vulgaris.
