Abstract
Bisphenols (BPs), which are mainly used in the production of polycarbonates and epoxy resins, are common endocrine disruptors (EDCs) in natural environments. Human mainly exposes to BPs via ingestion and skin. Previous studies have deteted BPs in human urine, serum, and milk samples, and children and pregnant women have a high level of exposure to to BPs. Based on international and national publications pertaining to BPs since 2009, this review describes the exposure to BPs in human urine, serum, and milk and summarizes neuroendocrine dysfunctions, oxidative stress injury and epigenetics changes caused by BPs, so as to provide insights into reducing the exposure to and health risk of BPs.

Triclosan, widely used in various personal care products, is one of the most common environmental endocrine disruptors in our life. It can be detected from water, soil and dust, and its environmental exposure level increased with consumption. Human body are exposed to triclosan through food and water, but the evidence that triclosan exposure leads to adverse health effects is not sufficient. This paper summarizes the progress of studies related to environmental concentration, population exposure and health risks of triclosan in recent years.

Uveal melanoma(UM)is the most frequent and life-threatening ocular malignancy in adults.Aberrant histone methylation contributes to the abnormal transcriptome during oncogenesis.However,a comprehensive understanding of histone methylation patterns and their therapeutic potential in UM remains enigmatic.Herein,using a systematic epi-drug screening and a high-throughput transcriptome profiling of histone methylation modifiers,we observed that disruptor of telomeric silencing-1-like(DOT1L),a methyltransferase of histone H3 lysine 79(H3K79),was activated in UM,especially in the high-risk group.Concordantly,a systematic epi-drug library screening revealed that DOT1 L inhibitors exhibited salient tumor-selective inhibitory effects on UM cells,both in vitro and in vivo.Combining Cleavage Under Targets and Tagmentation(CUT&Tag),RNA sequencing(RNA-seq),and bioinformatics analysis,we identified that DOT1 L facilitated H3K79 methylation of nicotinate phosphoribosyltransferase(NAPRT)and epigenetically activated its expression.Importantly,NAPRT served as an oncogenic accel-erator by enhancing nicotinamide adenine dinucleotide(NAD+)synthesis.Therapeutically,DOT1L inhi-bition epigenetically silenced NAPRT expression through the diminishment of dimethylation of H3K79(H3K79me2)in the NAPRT promoter,thereby inhibiting the malignant behaviors of UM.Conclusively,our findings delineated an integrated picture of the histone methylation landscape in UM and unveiled a novel DOT1L/NAPRT oncogenic mechanism that bridges transcriptional addiction and metabolic reprogramming.

The reversible and precise temporal and spatial regulation of histone lysine methyltransferases(KMTs)is essential for epigenome homeostasis.The dysregulation of KMTs is associated with tumor initiation,metastasis,chemoresistance,invasiveness,and the immune microenvironment.Therapeutically,their promising effects are being evaluated in diversified preclinical and clinical trials,demonstrating encouraging outcomes in multiple malignancies.In this review,we have updated recent understandings of KMTs'functions and the development of their targeted inhibitors.First,we provide an updated overview of the regulatory roles of several KMT activities in oncogenesis,tumor suppression,and im-mune regulation.In addition,we summarize the current targeting strategies in different cancer types and multiple ongoing clinical trials of combination therapies with KMT inhibitors.In summary,we endeavor to depict the regulation of KMT-mediated epigenetic landscape and provide potential epigenetic targets in the treatment of cancers.

Objective:To evaluate the effects of different pacing modes (unipolar/bipolar) under left bundle branch pacing(LBBP) on ventricular mechanical synchrony and myocardial work using the pressure-strain loop technique.Methods:Twenty-nine patients with LBBP due to symptomatic bradycardia were collected as LBBP group in Sun Yat-sen Memorial Hospital of Sun Yat-sen University from December 2018 to July 2020. Another 29 matched patients with right ventricular pacing (RVP) during the same period were also included as a RVP group. Each LBBP patient was programmed to different pacing modes (uni-/bio-polar) within 1 week after the operation.Under each pacing mode, the inter- and intra-ventricular mechanical synchronization were evaluated. Meanwhile, the global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE) were obtained by the left ventricular pressure-strain loops technique.Results:Compared with the RVP group, the mechanical synchrony in the LBBP group was significantly improved (all P<0.05). GWI, GCW, and GWE increased, while GWW decreased, and the differences were statistically significant (all P<0.05), there were no significant differences in ventricular mechanical synchronization, GWI, GCW, GWE, and GWW between unipolar and bipolar pacing in the LBBP group (all P>0.05), there were no significant differences in these parameters when increasing output voltage (all P>0.05). Conclusions:LBBP induces better mechanical synchronization and higher myocardial work efficiency than RVP. Different LBBP pacing modes do not affect ventricular mechanical synchronization and myocardial work efficiency.

The influence of circadian rhythm disorder on nonalcoholic fatty liver disease (NAFLD) has attracted more and more attention in recent years, and studies in China and globally have shown that individuals who work in shifts at night or often stay up late have a higher incidence rate of NAFLD-related hepatocellular carcinoma (NAFLD-HCC) than those with regular work and rest. This article summarizes the research advances in the effect of circadian rhythm system on the pathogenesis of NAFLD-HCC by regulating lipid metabolism, glucose metabolism, and intestinal flora, and it is pointed out that restoration of normal circadian rhythm has potential clinical significance in delaying the development and progression of disease.

Autophagy is a process of self-defense and self-repair of cells and tissues and plays an important role in regulating the body's immune inflammatory response and maintaining the homeostasis of liver cells. This article summarizes the mechanism of autophagy in the development and progression of autoimmune hepatitis (AIH) from the aspects of the role of autophagy in regulating immune inflammatory response, regulating immune signal transduction, and preventing overactivated innate immune response. It is believed that autophagy may reveal the mechanism of AIH and provide new ideas and methods for the research on AIH.

This study aimed to identify subtypes of genomic variants associated with the efficacy of immune checkpoint inhibitors (ICIs) by conducting systematic literature search in electronic databases up to May 31, 2021. The main outcomes including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and durable clinical benefit (DCB) were correlated with tumor genomic features. A total of 1546 lung cancer patients with available genomic variation data were included from 14 studies. The Kirsten rat sarcoma viral oncogene homolog G12C (KRASG12C) mutation combined with tumor protein P53 (TP53) mutation revealed the promising efficacy of ICI therapy in these patients. Furthermore, patients with epidermal growth factor receptor (EGFR) classical activating mutations (including EGFRL858R and EGFRΔ19) exhibited worse outcomes to ICIs in OS (adjusted hazard ratio (HR), 1.40; 95% confidence interval (CI), 1.01?1.95; P=0.0411) and PFS (adjusted HR, 1.98; 95% CI, 1.49?2.63; P<0.0001), while classical activating mutations with EGFRT790M showed no difference compared to classical activating mutations without EGFRT790M in OS (adjusted HR, 0.96; 95% CI, 0.48?1.94; P=0.9157) or PFS (adjusted HR, 0.72; 95% CI, 0.39?1.35; P=0.3050). Of note, for patients harboring the Usher syndrome type-2A (USH2A) missense mutation, correspondingly better outcomes were observed in OS (adjusted HR, 0.52; 95% CI, 0.32?0.82; P=0.0077), PFS (adjusted HR, 0.51; 95% CI, 0.38?0.69; P<0.0001), DCB (adjusted odds ratio (OR), 4.74; 95% CI, 2.75?8.17; P<0.0001), and ORR (adjusted OR, 3.45; 95% CI, 1.88?6.33; P<0.0001). Our findings indicated that, USH2A missense mutations and the KRASG12C mutation combined with TP53 mutation were associated with better efficacy and survival outcomes, but EGFR classical mutations irrespective of combination with EGFRT790M showed the opposite role in the ICI therapy among lung cancer patients. Our findings might guide the selection of precise targets for effective immunotherapy in the clinic.
