Animal studies indicated that P1 promoter-driven hepatocyte nuclear factor 4 alpha (HFN4A) prevents carcinogenesis in colitis. But the function of total HNF4A protein has not been fully investigated, and it was assumed to be involved in the colitis-neoplastic sequence. The aim of this study was to determine the clinical value of total P1-/P2-driven HNF4A combined with β-catenin in the colitis-neoplastic sequence. A total of 69 samples, including 4 normal colon tissues, 16 sporadic colorectal cancer (CRC) tissues, 35 inflammatory bowel disease (IBD) tissues, and 14 IBD-associated low-grade dysplasia tissues, were collected to assess P1-/P2-driven HNF4A and β-catenin expressions by immunohistochemical assay.

Increased expression of nuclear P1-/P2-driven HNF4A was observed in the colitis-associated colorectal neoplasm and sporadic CRC samples, compared with that in colitis samples. The parallel alterations between cytoplasmic β-catenin and nuclear P1-/P2-driven HNF4A were also verified. Silencing of P1-/P2-driven HNF4A expression in Caco2 cells decreased β-catenin expression and F-actin formation. Our results confirmed the elevated expressions of nuclear P1-/P2-driven HNF4A and cytoplasmic β-catenin in the colitis-neoplastic sequence, and both of them may be used as potential biomarkers to predict low-grade dysplasia.<br /><br /> Within a portion of the 2020 professional practice and "salary survey," to update key information regarding neuropsychology postdoctoral trainees.<br /><br /> Postdoctoral trainees were contacted via a variety of membership listings, including the listserv used by the program directors of the Association of Postdoctoral Programs in Clinical Neuropsychology (APPCN). Invitations sent in multiple waves to members of numerous neuropsychological organizations via e-messages and physical postcards included the request that postdoctoral trainees participate. The survey website was opened on January 17, 2020 and closed on April 2, 2020, during which time a total of 178 postdoctoral trainees in the USA and 3 in Canada participated.<br /><br /> Response rate was estimated to be 56.4%, which adequately represents the target sample. The modal postdoctoral trainee is a woman whose internship was American Psychological Association (APA)-accredited and whose postdoctoral training is in an APPCN program that adheres to Houston Conference training guidelines. Extensive clinical experiences in neuropsychology in the form of externship practica and during internship were reported by the majority of trainees prior to postdoctoral training. There are few differences between APPCN and non-APPCN trainees and reported training experiences. Job satisfaction is high. Salaries appear to have increased substantially in recent years. There is universal interest in pursuing board certification. Support for the empirical foundations justifying assessment of response validity is high.<br /><br /> Surveys of postdoctoral trainees continue to provide valuable perspectives regarding training background, clinical experiences, practice beliefs, and incomes of individuals who will soon launch their careers in clinical neuropsychology.<br /><br />Surveys of postdoctoral trainees continue to provide valuable perspectives regarding training background, clinical experiences, practice beliefs, and incomes of individuals who will soon launch their careers in clinical neuropsychology.<br /><br /> Recent drug approvals have increased the number of therapies available for inflammatory bowel disease (IBD), making it difficult for patients to navigate available treatment options. We examined patient decision-making surrounding biologic and small-molecule therapies in an international cohort of patients from the United States, Canada, and the United Kingdom using conjoint analysis (CA), a form of tradeoff analysis examining how respondents make complex decisions.<br /><br /> We performed a CA survey that quantified the relative importance of therapy attributes (eg, efficacy, adverse effects) in decision-making. Patients with IBD were recruited from the general population and through specialty IBD clinics. We used a hierarchical Bayes analysis to model individual patients' preferences and compared the relative importance of medication attributes between countries and practice settings. Using a series of multivariable linear regression models, we assessed whether demographic and clinical characteristics (eg, IBD subharacteristics.Transcriptomic deregulation by epigenetic mechanisms plays a crucial role in the heterogeneous progression of colorectal cancer (CRC). Herein, we first demonstrated that the frequencies of the aberrancies of DNA methylation-correlated (METcor) and microRNA (miRNA)-correlated (MIRcor) genes were significantly co-regulated. Next, through integrative clustering of the expression profiles of METcor and MIRcor genes, four molecular subtypes were identified in CRC patients from The Cancer Genome Atlas and then validated in four independent datasets. More importantly, the four subtypes were well characterized and showed distinct clinical and molecular features (i) S-I high metabolic activity, sensitive to 5-fluorouracil-based chemotherapy and good prognosis; (ii) S-II moderate metabolic activity, marked proliferation, frequent KRAS mutation and intermediate prognosis; (iii) S-III moderate metabolic activity, marked proliferation, promoter DNA hypermethylation, high mutation burden, frequent BRAF and EGFR mutations, moderate levels of epithelial-mesenchymal transition (EMT) and transforming growth factor β (TGFβ) signals, immune-inflamed phenotype, sensitive to cetuximab and death protein-1 inhibitor treatment and relatively poor prognosis and (iv) S-IV miRNA overexpression, stem/serrated/mesenchymal-like properties, hypoxia, high levels of EMT and TGFβ signals, immune-excluded phenotype and poor prognosis. Overall, this study established a molecular classification based on epigenetically regulated gene expression profiles, thereby providing a better understanding of the epigenetic mechanisms underlying CRC heterogeneity.
