Background: Acute respiratory distress syndrome (ARDS) / acute lung injury (ALI) is a serious medical disease characterized by pulmonary dysfunction and inflammation. This study aims to determine the main molecular modules linked to ARDS and investigate the role of Fibulin-1 (FBLN1) in regulating ferroptosis in ARDS.

Methods: Weighted Gene Co-expression Network Analysis (WGCNA) was employed on the GSE263867 dataset to find key modules associated with ALI.

The role of SEC14L4 in esophageal squamous cell cancer: insights into clinical relevance and molecular pathways.

Background: Esophageal squamous cell cancer (ESCC) is the most common type of esophageal cancer. This study aimed to elucidate the role of Saccharomyces cerevisiae-like 4 () in ESCC.

Methods: To elucidate the role of in ESCC, this study analyzed the clinical data, gene sequencing data, and other relevant data retrieved from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) of the National Center for Biotechnology Information.

The carcinogenesis of esophageal squamous cell cancer is positively regulated by USP13 through WISP1 deubiquitination.

The objective was to determine whether USP13 stabilizes WISP1 protein and contributes to tumorigenicity and metastasis in ESCC through the Wnt/CTNNB1 signaling pathway. ESCC cell lines (KYSE150 and TE10) were treated with the proteasome inhibitor MG-132, followed by siRNA screening of deubiquitinases (DUBs) to identify regulators of WISP1. Mass spectrometry, immunoprecipitation, and in vitro functional assays were conducted to explore the interaction between USP13 and WISP1 and to assess the effects of USP13 downregulation on cell proliferation, migration, invasion, epithelial-mesenchymal transition (EMT), and apoptosis.

A brain-to-gut signal controls intestinal fat absorption.

Although fat is a crucial source of energy in diets, excessive intake leads to obesity. Fat absorption in the gut is prevailingly thought to occur organ-autonomously by diffusion. Whether the process is controlled by the brain-to-gut axis, however, remains largely unknown.

Thoracoscopic Anatomic Left Lower Lobe S6b Subsegmentectomy.

Although thoracoscopic lung segmentectomy has made significant achievements, there is little known about how to perform subsegmentectomy, which can also acquire a safe margin for curability but with more pulmonary volume reserved. This report presents the surgical procedure for subsegmental anatomic resection of left lower lobe subsegment 6b guided by the simulation of bronchovascular branching through the use of 3-dimensional computed tomographic bronchography and angiography.

Subxiphoid and subcostal thoracoscopic surgical approach for thymectomy.

Background: The continuous evolvement of minimally invasive thymectomy over the last decades has potential advantages over trans-sternal thymectomy with similar oncologic outcomes of thymoma and complete remission for myasthenia gravis patients. A variety of different minimally invasive approaches have been described previously. The aim of this article is to present our subxiphoid and subcostal approaches in thymectomy for patients with myasthenia gravis and thymomas and to investigate the early surgical outcomes of these patients.

Follicular cytotoxic CD8 T cells present high cytokine expression, and are more susceptible to Breg-mediated suppression in non-small cell lung cancer.

Tumor-infiltrating CD8 T cells are instrumental to antitumor immunity. In this study, we found that a subset of CXCR5-expressing CD8 T cells, termed follicular cytotoxic T (Tfc) cells, potently infiltrated the untreated tumors from non-small cell lung cancer (NSCLC) patients. On average, Tfc cells represented 14% of total tumor-infiltrating CD8 T cells and 6.

β dysfunction contributes to adiposity by regulating the cross-talk of mature adipocytes and preadipocytes.

Overnutrition results in adiposity and chronic inflammation with expansion of white adipose tissue (WAT). However, genetic factors controlling fat mass and adiposity remain largely undetermined. We applied whole-exome sequencing in young obese subjects and identified rare gain-of-function mutations in β-catenin associated with increased obesity risk.

NCBP1 promotes the development of lung adenocarcinoma through up-regulation of CUL4B.

Lung cancer is the most frequent cancer type and is the leading cause of tumour-associated deaths worldwide. Nuclear cap-binding protein 1 (NCBP1) is necessary for capped RNA processing and intracellular localization. It has been reported that silencing of NCBP1 resulted in cell growth reduction in HeLa cells.

Uterus globulin associated protein 1 (UGRP1) is a potential marker of progression of Graves' disease into hypothyroidism.

Approximately 20% of Graves' disease (GD) patients may result eventually in hypothyroidism in their natural course. Uterus globulin-associated protein 1 (UGRP1) was associated with GD in our previous study. Here we investigated the role of UGRP1 in the development of autoimmune thyroid disease (AITD).

Surgical treatment of posterior mediastinal neurogenic tumors.

Background: Posterior mediastinal neurogenic tumors are among the most frequent mediastinal masses in adults. These tumors may be dumbbell shaped, extending into the spinal canal, exclusively paraspinal or apical tumors extending in the cervical region. In this report, we present our experience in the surgical resection of these tumors and discuss the surgical strategies for such tumors.

SRC1 Deficiency in Hypothalamic Arcuate Nucleus Increases Appetite and Body Weight.

Appetite is tightly controlled by neural and hormonal signals in animals. In general, steroid receptor co-activator 1 (SRC1) enhances steroid hormone signalling in energy balance and serves as a common co-activator of several steroid receptors, such as estrogen and glucocorticoid receptors. However, the key roles of SRC1 in energy balance remain largely unknown.

Surgical treatment of thoracic dumbbell tumors.

Background: Thoracic dumbbell tumors are uncommon neoplasms arising from neurogenic elements of the posterior mediastinum. Surgical removal of these tumors with mediastinal, neuroforaminal and intraspinal components can often be challenging. The purpose of this study is to present our experience of single-stage removal of dumbbell tumors of the posterior mediastinum and to discuss the surgical strategies for such tumors.

Clinical and Physiological Characterization of Elevated Plasma Glucagon-Like Peptide-1 Levels (Hyperglipemia) in a Dipeptidyl Peptidase IV Mutation Carrier.

The clinical application of dipeptidyl peptidase IV inhibitors (DPP4i) increasing active glucagon-like peptide-1 (AGLP-1) levels has been linked to pancreatitis, pancreatic tumors, and cardiovascular events. However, mutations in humans or the long-term outcomes of high glucagon-like peptide-1 (GLP-1) level exposure have not been reported. A trio family with a proband showing an extremely high AGLP-1 level [defined here as hyperglipemia (hyper-glucagon-like peptide-1-emia)] were conducted whole-exome sequencing for potential pathogenic genetic defects.

Stanniocalcin2 acts as an anorectic factor through activation of STAT3 pathway.

The regulation of food intake and body weight has been hotly investigated. In the present study, we show that stanniocalcin2 (STC2), a cytokine ubiquitously expressed and especially upregulated in many types of human cancers, has a regulatory role in food intake and weight loss. Systemic treatment of C57BL/6 mice with recombinant STC2 protein resulted in decreased food intake and body weight, whereas energy expenditure was not affected.

Some Shanghai Clinical Center f a role of Niemann-Pick type C1 () for obesity traits. However, whether the loss-of-function mutations in cause adiposity in humans remains unknown. We recruited 25 probands with rare autosomal-recessive Niemann-Pick type C (NP-C) disease and their parents in assessment of the effect of heterozygous mutations on adiposity.

Function of follicular helper T cell is impaired and correlates with survival time in non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) represents one of the most common and aggressive cancers worldwide. The PD-1/PD-L1 interaction plays important roles in cancer immunology, and expression of PD-L1 has been discovered in NSCLC tumor cells. Since follicular helper T (Tfh) cells have characteristic high PD-1 expression, we therefore investigated the inflammatory status of Tfh in NSCLC.
