Abstract
OBJECTIVE Oral lichen planus (OLP) is a T cell-mediated inflammatory disease with uncertain etiology. Exosomes are cell-derived vesicles containing biological cargo, being associated with the development of multiple inflammatory diseases. The present study aims to investigate the role of T cell-derived exosomes in the pathogenesis of OLP. METHODS Exosomal marker CD63 was detected in OLP lesions by immunohistochemistry. Twenty-three cytokines in T cell-derived exosomes were assessed using luminex xMAP-based assay. After co-incubating with exosomes, the apoptosis of keratinocytes and the proliferation of Jurkat cells were assessed via flow cytometry and cell counting kit-8 assay, respectively. RESULTS CD63 was highly expressed in the lymphocyte infiltrated areas of OLP lesions. OLP T cell-derived exosomes contained upregulated interleukin-7, -10, -12, -17 and downregulated interleukin-1β, -5, and interferon-γ. Both exosomes from OLP patients and controls induced the apoptosis of keratinocytes and altered their morphology. Moreover, healthy control-derived exosomes markedly inhibited the proliferation of Jurkat cells, whereas OLP-derived exosomes exhibited no inhibitory effect. CONCLUSIONS OLP T cell-derived exosomes have an aberrant cytokine profile and could trigger the apoptosis of keratinocytes in vitro, which may be involved in the pathogenesis of OLP.

Potential role of gut microbiota, the proto-oncogene PIKE (Agap2) and cytochrome P450 CYP2W1 in promotion of liver cancer by alcoholic and nonalcoholic fatty liver disease and protection by dietary soy protein. Chem Biol Interact 2020; 325:109131.

Abstract
We have previously demonstrated promotion of diethylnitrosamine (DEN) initiated liver tumorigenesis after feeding diets high in fat or ethanol (EtOH) to male mice. This was accompanied by hepatic induction of the proto-oncogene PIKE (Agap2). Switch of dietary protein from casein to soy protein isolate (SPI) significantly reduced tumor formation in these models. We have linked EtOH consumption in mice to microbial dysbiosis. Adoptive transfer studies demonstrate that microbiota from mice fed ethanol can induce hepatic steatosis in the absence of ethanol suggesting that microbiota or the microbial metabolome play key roles in development of fatty liver disease. Feeding SPI significantly changed gut bacteria in mice increasing alpha diversity (P < 0.05) and levels of Clostidiales spp. Feeding soy formula to piglets also resulted in significant changes in microbiota, the pattern of bile acid metabolites and in inhibition of the intestinal-hepatic FXR/FGF19-SHP pathway which has been linked to both steatosis and hepatocyte proliferation. Moreover, feeding SPI also resulted in induction of hepatic PPARα signaling and inhibition of PIKE mRNA expression coincident with inhibition of steatosis and cancer prevention. Feeding studies in the DEN model with differing dietary fats demonstrated tumor promotion specific to the saturated fat, cocoa butter relative to diets containing olive oil or corn oil associated with microbial dysbiosis including dramatic increases in Lachnospiraceae particularly from the genus Coprococcus. Immunohistochemical analysis demonstrated that tumors from EtOH-fed mice and patients with alcohol-associated HCC also expressed high levels of a novel cytochrome P450 enzyme CYP2W1. Additional adoptive transfer experiments and studies in knockout mice are required to determine the exact relationship between soy effects on the microbiota, expression of PIKE, CYP2W1, PPARα activation and prevention of tumorigenesis.

Abstract
BACKGROUND Oral lichen planus (OLP) is a common T-cell-mediated immunological disease. Hypoxia-inducible factor 1 alpha (HIF1α) plays an integral role in the glycolytic metabolism that facilitates immune functions from boosting cellular proliferative capacity to driving T-cell differentiation. In general, phospholipase D2 (PLD2) is required for HIF1α regulation. However, the involvement of HIF1α and PLD2 in dysfunctional T-cell immunity of OLP remains elusive. METHODS HIF1α and PLD2 expression in OLP lesions were determined by qRT-PCR, immunohistochemistry and immunofluorescence staining, and correlation analysis was carried out between their expressions. HIF1α or PLD2 silencing in T cells was performed to investigate the glycolytic alteration. Then their involvement in T-cell immunobiology was evaluated by detecting cell proliferation, cell cycle, apoptosis, and effector subsets differentiation. Additionally, the modulation of HIF1α on PLD2 expression and the engagement of mTOR in this process were explored. RESULTS HIF1α and PLD2 protein were highly expressed in OLP lesions and they were both observed in large numbers of local CD3+ T cells in OLP. Besides, HIF1α expression was positively correlated with PLD2 expression in OLP. Both HIF1α and PLD2 promoted T-cell proliferation and pro-inflammatory phenotype differentiation, which was associated with the upregulation of glycolysis mediated by HIF1α or PLD2. Moreover, HIF1α induced PLD2 expression in an mTOR-independent way. CONCLUSIONS HIF1α/PLD2 axis was supposed to be critical regulatory signaling involved in the T-cell immunity of OLP.

Abstract
CONTEXT Patients with adrenocortical carcinoma (ACC) often fail mitotane treatment and deal with severe toxicity, marking the relevance of predictive parameters for treatment outcome. OBJECTIVE Determine the effects of mitotane in primary ACC cultures, and correlate sensitivity with patient and tumor characteristics. METHODS In 32 primary ACC cultures, the effects of mitotane on cell growth and cortisol production were determined. RRM1, SOAT1, and CYP2W1 expression were assessed using reverse transcription-polymerase chain reaction and immunohistochemistry. RESULTS The median percentage cell amount inhibition in primary ACC cultures at 50 µM mitotane was 57%. Seven patients were classified as nonresponders, 14 as partial responders, and 11 as responders. The mean median effective concentration (EC50) value of mitotane for inhibition of cell amount in responders was 14.2 µM (95% CI, 11.3-17.9), in partial responders 41.6 µM (95% CI, 33.5-51.8), and could not be calculated in nonresponders. The percentage cortisol-producing ACC was 14%, 43%, and 73% for nonresponders, partial responders, and responders (P = 0.068). Mitotane inhibited cortisol production with a mean EC50 of 1.4 µM (95% CI, 0.9-2.1), which was considerably lower than the EC50 on cell growth. RRM1, SOAT1, and CYP2W1 expression levels were not predictive for mitotane sensitivity in vitro. CONCLUSION Direct antitumor effects of mitotane on human primary ACC cultures are highly variable between patients, reflecting heterogeneous responses in patients. Cortisol was inhibited at lower concentrations, compared with its effect on cell amount. Cortisol secretion by ACC might be associated with enhanced mitotane sensitivity due to increased direct antitumor effects of mitotane.

Micro RNA-4651 Serves as a Potential Biomarker for Prognosis When Selecting Hepatocellular Carcinoma Patients for Postoperative Adjuvant Transarterial Chemoembolization Therapy. Hepatol Commun 2018; 2:1259-1273. [PMID: 30288479 PMCID: PMC6167067 DOI: 10.1002/hep4.1245] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2017] [Accepted: 07/19/2018] [Indexed: 12/13/2022] Open
Abstract
Our previous reports have shown that microRNA-4651 is a potential early diagnostic and prognostic marker for hepatocellular carcinoma. We aimed to investigate whether microRNA-4651 modified postoperative adjuvant transarterial chemoembolization (pa-TACE) to improve the prognosis of hepatocellular carcinoma. A hospital-based retrospective study, including 302 patients with advanced-stage hepatocellular carcinoma who received tumor resection or tumor resection plus pa-TACE as an initial therapy, was conducted to assess the effects of microRNA-4651 on pa-TACE treatment. MicroRNA-4651 expression in tumor tissues was tested using the TaqMan-PCR technique. The sensitivity of tumor cells to doxorubicin (an anticancer drug used in pa-TACE procedure) was analyzed by the half-maximal inhibitory concentration (IC50). Upregulated microRNA-4651 expression in tumor tissues can improve the therapeutic response of patients with hepatocellular carcinoma on pa-TACE (hazard ratios [95% confidence intervals] = 0.32 [0.22-0.46] for death risk and 0.39 [0.28-0.56] for tumor-recurrence risk, respectively), but downregulated expression cannot. Functional analyses-displayed microRNA-4651 mimics decreased while its inhibitor increased the IC50 of tumor cells to doxorubicin (0.65 [0.61-0.69] versus 2.17 [1.98-2.37] µM). Cytochrome P450 2W1 was shown as a possible target of microRNA-4651. Additionally, dysregulation of microRNA-4651 also affected the clinical pathological features of hepatocellular carcinoma and was an independent prognostic factor for this cancer. Conclusion: These results indicate that increasing microRNA-4651 expression may be beneficial for pa-TACE in improving hepatocellular carcinoma prognosis.

Abstract
Interindividual and interethnic variability of drug responses could be attributed to the differences of genetic polymorphisms in the drug metabolizing enzymes and transporters genes among the populations. Here we reviewed the studies of genetic variations in Uyghur Chinese of fifteen CYP450 genes including CYP1A1, CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP2J2, CYP2W1, CYP3A4, CYP3A5, CYP4A11, and CYP17A1, which totally covered 277 variants. We also collected the data of 277 variants covered in our study in two extensive population sequencing projects, the International HapMap Project (Hap-Map) and the 1000 Genomes Project and compared them with the data of Uyghur Chinese. The results suggested that remarkable differences of variants allele frequencies of CYP450 genes were existed among Uyghur Chinese and other world populations and drug doses should be adjusted clinically in Uyghur in contrast to Han Chinese and Caucasians.
