Background: Failure in the endometrial receptivity may account for a significant number of infertility cases including unexplained infertility in women. Reduction in the endometrial estrogen receptor-alpha (ER-α) expression during implantation may be a critical event that coincides with the expression of specific genes and the formation of a receptive endometrium. The aim of the present study was to assess the expression of ER-α in the mid-secretory phase in the endometrium of women with unexplained infertility...

Cancer is a major leading cause of disease-related death in the world. The severe impact of cancer can be attributed to poor understanding of the mechanisms involved in earliest steps of the metastatic cascade, specifically invasion into the surrounding stroma and intravasation into the blood capillaries. However, conducting integrated biological studies of invasion and intravasation have been challenging, within in vivo models and traditional in vitro assay, due to difficulties in establishing a precise tumor microenvironment...

Nirmala Tilija Pun, Pil-Hoon Park
BACKGROUND AND PURPOSE: Adiponectin potently suppresses inflammatory mediator production. Autophagy is known to play a critical role in modulating inflammatory responses by adiponectin. However, the underlying mechanisms are not clearly understood. Interaction between Beclin-1 and Bcl-2 is a critical event in autophagy induction. We examined the effects of globular adiponectin (gAcrp) on the Beclin-1/Bcl-2 association and its underlying mechanisms. EXPERIMENTAL APPROACH: The effect of gAcrp on the interaction between Beclin-1 and Bcl-2 was examined by immunoprecipitation followed by Western blotting...

Osteosarcoma (OS) is the most frequent bone-forming malignancy in children and adolescents. Concerning its molecular landscape, there is no a direct relationship with a specific gene, but a combination of genetic events. A broad spectrum of activated oncogenes and downregulated suppressor genes has been already explored and considered crucial for its progressive pathogenesis. Mechanisms of gene deregulation include amplifications, point mutations, allelic losses and also epigenetic abnormalities such as aberrant promoter methylation...

REVIEW
Juan Marcos Gonzalez
BACKGROUND: Stated-preference methods have been widely used to evaluate patient-relative preferences for the benefits and potential harms of psoriasis treatments. However, risk tolerance measures for treatment-related harms, a corollary of preferences, are rare despite their critical role in shared decision making and regulatory benefit-risk evaluations. This article presents a method to enhance information on patient risk tolerance through previously published preference results. OBJECTIVE: The objective of this article was to conduct the first meta-analysis of preferences to characterize the distribution of patients' maximum acceptable risk of harms associated with psoriasis treatments...

DNA diffusion assay is a simple, sensitive and reliable technique which allows the assessment of programmed cell death (PCD) or necrosis events based on nuclear morphology. It consists in isolating nuclei from plant material, which are then embedded in agarose and subjected to lysis in alkaline buffers. Under these conditions, and due to the presence of abundant alkali-labile sites in the DNA, small pieces of DNA diffuse in the agarose gel giving a specific halo appearance when stained with fluorescent dyes like DAPI (4',6-diamidino-2-phenylindole)...

Acetaminophen (APAP) overdose can cause severe liver failure even death. Nearly half of drug-induced liver injury is attributed to APAP in the US and many European countries. Oxidative stress has been validated as a critical event involved in APAP-induced liver failure. p62/SQSTM1, a selective autophagy adaptor protein, is reported to regulate Nrf2-ARE antioxidant pathway in response to oxidative stress. However, the exact role of p62-keap1-Nrf2 antioxidant pathway in APAP-induced hepatotoxicity remains unknown...

The poor outcome of hepatocellular carcinoma (HCC) is mainly due to the development of fast growth, invasion and metastasis. The role of TET2 has been implicated in some cancer types, but its role and mechanisms in HCC remains elusive. In this study, our findings indicated that TET2 expression frequently increased in HCC and that TET2 expressional upregulation correlated with HCC progression. TET2 knockdown inhibited HCC cells proliferation in vitro and growth in vivo, and inhibited the invasion potential of HCC cells...

Ashish Kumar, Chandrima Shaha
Mitophagy, the selective degradation of mitochondria by autophagy, is crucial for the maintenance of healthy mitochondrial pool in cells. The critical event in mitophagy is the translocation of cytosolic Parkin, a ubiquitin ligase, to the surface of defective mitochondria. This study elucidates a novel role of SESN2/Sestrin2, a stress inducible protein, in mitochondrial translocation of PARK2/Parkin during mitophagy. The data demonstrates that SESN2 downregulation inhibits BECN1/Beclin1 and Parkin interaction, thereby preventing optimum mitochondrial accumulation of Parkin...

TCRs recognize peptides on MHC molecules and induce downstream signaling, leading to activation and clonal expansion. In addition to the strength of the interaction of TCRs with peptides on MHC molecules, mechanical forces contribute to optimal T cell activation, as reflected by the superior efficiency of immobilized TCR-cross-linking Abs compared with soluble Abs in TCR triggering, although a dedicated mechanotransduction module is not identified. We found that the professional mechanosensor protein Piezo1 is critically involved in human T cell activation...

Being realistic while helping our patients is this issue's theme. Given the volume of tasks required in family medicine, recommendations for improvements in direct care or care measurement cannot just be evidence-based but must also be realistic. On the list of realistic: ordering antipsychotics for symptoms of dementia in the elderly, despite recommendations to not do so; ordering antidepressants without fear that the patient could develop hypertension; mental health care providers in primary care offices; forced choice for opioid management; plus agenda setting for visit efficiency...

Long noncoding RNAs (LncRNAs) are one of the emerging regulators which are involved in diverse biological processes. LncRNAs can participate in the regulation of gene expression via various ways in the cytoplasm and the nucleus. The function of the nuclear lncRNAs has been studied a lot. Recent studies have shown that the regulatory roles of cytoplasmic lncRNA, including membrane lipid associated lncRNA, may open an unexplored mechanistic territory. LncRNA dysregulated expression represents a common event in pathogenesis of a variety of human genetic diseases including cancer...

Yuling Han, T Prabhakar Clement
The Deepwater Horizon (DWH) accident, one of the largest oil spills in U.S. history, contaminated several beaches located along the Gulf of Mexico (GOM) shoreline. The residues from the spill still continue to be deposited on some of these beaches. Methods to track and monitor the fate of these residues require approaches that can differentiate the DWH residues from other types of petroleum residues. This is because, historically, the crude oil released from sources such as natural seeps and anthropogenic discharges have also deposited other types of petroleum residues on GOM beaches...

BACKGROUND AND AIMS: Pancreatic cancer organoids are tumor models of individualized human pancreatic ductal adenocarcinoma (PDA), created from surgical specimens and used for personalized treatment strategies. Unfortunately the vast majority of patients with PDA are not operative candidates. Creation of human PDA organoids at the time of initial tumor diagnosis is therefore critical. Our aim was to assess the feasibility of creating human PDA organoids by EUS fine-needle biopsy (EUS-FNB) in patients with PDA...
