- Esophageal squamous cell cancer (ESCC) remains an aggressive malignant tumor with limited therapeutic options and poor prognosis. This study aims to uncover novel diagnostic markers and therapeutic targets by investigating molecular drivers of ESCC pathogenesis using integrated omics and functional assays. The gene expression profiles of ESCC tissues were compared with those of normal tissues. SEC14L4 expression was evaluated through qPCR, Western blot, and immunohistochemistry (IHC). Functional roles of SEC14L4 were assessed through cell proliferation, colony formation, apoptosis, migration, and invasion assays. Co-immunoprecipitation (Co-IP) and mass spectrometry were used to discover SEC14L4-interacting proteins. Ubiquitination assays assessed the degradation of DDX3X. The MAPK pathway and ferroptosis markers were analyzed by Western blot to investigate the downstream effects of SEC14L4. In vivo tumor models were used to validate SEC14L4's oncogenic role. SEC14L4 was markedly overexpressed in ESCC tissues, correlating with advanced tumor stage and reduced overall survival. In vitro, SEC14L4 promoted ESCC cell proliferation, migration, and colony formation, while inhibiting apoptosis, while its knockdown reduced these effects. DDX3X overexpression rescued these phenotypes. Co-IP and mass spectrometry confirmed a direct interaction between SEC14L4 and DDX3X, and SEC14L4 was found to inhibit DDX3X ubiquitination via RNF39. SEC14L4 promotes ESCC progression by activating the MAPK signaling pathway and inhibiting ferroptosis. In vivo, SEC14L4 knockdown significantly inhibited tumor growth. SEC14L4 facilitates ESCC development by inhibiting the ubiquitination and degradation of DDX3X by RNF39. - Source: PubMed

Huang DayuWang DongdongWang YouboWang XuanHe ChangDu YuMa QinyunChen XiaofengWang An - Biliary atresia (BA) is a rare pediatric cholestatic disorder characterized by progressive bile duct inflammation and fibrosis. The underlying molecular mechanisms of BA remain poorly defined. This study aimed to identify susceptibility genes causally associated with BA by integrating genome-wide association study (GWAS) and transcriptomic data, and to explore their potential immunopathological roles. - Source: PubMed

Wang AnWang YouboChen YanhuiWan PosumSaeed AnwaarMa QinyunChen Xiaofeng - The use of protein biomarkers in blood for clinical settings is limited by the cost and accessibility of traditional venipuncture sampling. The dried blood spot (DBS) technique offers a less invasive and more accessible alternative. However, protein stability in DBS has not been well evaluated. Herein, we deployed a quantitative LC-MS/MS system to construct proteomic atlases of whole blood, DBSs, plasma, and blood cells. Approximately 4% of detected proteins' abundance was significantly altered during blood drying into blood spots, with overwhelming disturbances in cytoplasmic fraction. We also reported a novel finding suggesting a decrease in the level of membrane/cytoskeletal proteins (SLC4A1, RHAG, DSC1, DSP, and JUP) and an increase in the level of proteins (ATG3, SEC14L4, and NRBP1) related to intracellular trafficking. Furthermore, we identified 19 temporally dynamic proteins in DBS samples stored at room temperature for up to 6 months. There were three declined cytoskeleton-related proteins (RDX, SH3BGRL3, and MYH9) and four elevated proteins (XPO7, RAN, SLC2A1, and SLC29A1) involved in cytoplasmic transport as representatives. The instability was governed predominantly by hydrophilic proteins and enhanced significantly with an increasing storage time. Our analyses provide comprehensive knowledge of both short- and long-term storage stability of DBS proteins, forming the foundation for the widespread use of DBS in clinical proteomics and other analytical applications. - Source: PubMed

Sun WeifenHuang AoWen ShuboYang RuicongLiu Xiling - Since TNM staging has limitations for predicting post-operative outcomes and relapse, more effective prediction tools need to be researched and developed. Lymphovascular invasion, LVI, as a histopathological feature, has been widely shown to have a correlation with poor prognosis and early recurrence of lung adenocarcinoma (LUAD). However, LVI assessment is limited by subjective bias, and therefore its efficacy in practical clinical application needs further clarification. The aim of this study was to formulate a new signature based on LVI-related genes to predict prognosis and recurrence in patients with lung adenocarcinoma. - Source: PubMed
