In this review, we introduced and summarized the cellular processes that govern hypoxia-driven regulation of histone methylation in the context of cancer biology. click here We also discussed the emerging roles of histone methyltransferases and demethylases in epigenetic response to hypoxia.Tumors can be classified as cold or hot according to the degree of immune cell infiltration into tumor tissues; cold tumors are insensitive to either chemotherapy or immunotherapy and are associated with poor prognosis. Recent studies have shown that STAT3 signaling molecules hinder the conversion of cold to hot tumors by regulating immunosuppressive molecule secretion and immunosuppressive cell functions. This review aims to present the most recent studies on how STAT3 regulates cold tumor formation and discuss its research status in cancer therapy. We also present insight for designing new therapeutic strategies to "heat" tumors and provide a reference for tumor immunotherapy.Background Acral melanoma (AM) is an epidemiologically and molecularly distinct entity that is underrepresented in clinical trials on immunotherapy in melanoma. We aimed to analyze the real-world efficacy of anti-PD-1 antibodies in advanced AM. Patients and methods We retrospectively evaluated unresectable stage III or stage IV AM patients treated with an anti-PD-1 antibody in any line at 21 Japanese institutions between 2014 and 2018. The clinicobiologic characteristics, objective response rate (ORR, Response Evaluation Criteria in Solid Tumors), survival estimated using Kaplan-Meier analysis, and toxicity (Common Terminology Criteria for Adverse Events 4.0.) were analyzed to estimate the efficacy of the anti-PD-1 antibodies. Results In total, 193 patients (nail apparatus, 70; palm and sole, 123) were included in the study. Anti-PD-1 antibody was used as first-line therapy in 143 patients (74.1%). Baseline lactate dehydrogenase (LDH) was within normal level in 102 patients (52.8%). The ORR of all patients was 16.6% (complete response, 3.1%; partial response, 13.5%), and the median overall survival (OS) was 18.1 months. Normal LDH levels showed a significantly stronger association with better OS than abnormal levels (median OS 24.9 vs 10.7 months; P less then 0.001). Although baseline characteristics were similar between the nail apparatus and the palm and sole groups, ORR was significantly lower in the nail apparatus group (6/70 patients [8.6%] vs 26/123 patients [21.1%]; P=0.026). Moreover, the median OS in this group was significantly poorer (12.8 vs 22.3 months; P=0.03). Conclusions Anti-PD-1 antibodies have limited efficacy in AM patients. Notably, patients with nail apparatus melanoma had poorer response and survival, making nail apparatus melanoma a strong candidate for further research on the efficacy of novel combination therapies with immune checkpoint inhibitors.The publisher regrets that this article has been temporarily removed.

Methods Forty acid-etched dentin surfaces were randomly allocated into five groups, and pretreated with one of the primers 0.1, 1.0, and 10 mmol/L DMA/ dimethyl sulfoxide (DMSO) solutions, pure DMSO, and deionized water (control) before bonding. The bonded teeth of each group were randomly distributed into an immediate subgroup (water storage at 37 °C for 24 h) and an aged subgroup (thermocycling, 5-55 °C, 10,000 times). The teeth were sectioned into 0.9 mm slabs; two middle slabs were used for nanoleakage evaluation, while the remaining slabs were sectioned into beams for micro-tensile bond strength (MTBS) test.
