QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

Complete analysis of the B-cell response to a protein antigen, from in vivo germinal centre formation to 3-D modelling of affinity maturation [PDF]

open access: yes, 2003
Somatic hypermutation of immunoglobulin variable region genes occurs within germinal centres (GCs) and is the process responsible for affinity maturation of antibodies during an immune response.

Novel ATR/PARP1 Dual Inhibitors Demonstrate Synergistic Antitumor Efficacy in Triple‐Negative Breast Cancer Models

open access: yesAdvanced Science, EarlyView.
Novel ATR/PARP1 dual inhibitors are developed for the first time. Advanced lead B8 effectively reduces cell viability in vitro and suppresses tumor growth in vivo, with better potency than ATRi and PARPi alone or in combination. Mechanistically, B8 induces apoptosis, arrests the cell cycle, and inhibits cancer cells colony formation, migration, and ...

Gene conversion in human rearranged immunoglobulin genes [PDF]

open access: yes, 2006
Over the past 20 years, many DNA sequences have been published suggesting that all or part of the V<sub>H</sub> segment of a rearranged immunoglobulin gene may be replaced in vivo. Two different mechanisms appear to be operating. One of these

Expression of heavy chain‐only antibodies can support B‐cell development in light chain knockout chickens

open access: yesEuropean Journal of Immunology, 2016
Since the discovery of antibody‐producing B cells in chickens six decades ago, chickens have been a model for B‐cell development in gut‐associated lymphoid tissue species.

Franklin's disease: immunoglobulin heavy chain disease.

open access: yesStem cell investigation, 2015
A 64-year-old male presented with persistent fatigue, weakness and abdominal discomfort. He was found to have pancytopenia and hepatosplenomegaly. His bone marrow examination was mildly hypocellular with trilineage hematopoiesis. Serum protein electrophoresis revealed broad beta protein area but no gamma monoclonal spike (A).

Potent Cross‐neutralizing Antibodies Reveal Vulnerabilities of Henipavirus Fusion Glycoprotein

open access: yesAdvanced Science, EarlyView.
Hendra and Nipah viruses (HNVs) pose significant threats to global health. This work reports potent cross‐neutralizing antibodies targeting the fusion glycoprotein (F) and reveals shared features of these antibodies and vulnerabilities of F, thereby guiding the rational design of countermeasures against HNVs and similar pathogens.

Population Genetics of the Heavy Chain Immunoglobulin Allotypes in the Rabbit

open access: yesExperimental Biology and Medicine, 1972
Synthesis of the heavy immunoglobulin chain is controlled by two genes, one being in control of the variable, the second in control of the constant portion of the chain (1-3). Elucidation of the relation between the genes for constant and variable portions of the heavy chain and of the mechanism of assembly are crucial for an analysis of the generation

Mechanical Stress Induced NOX2 Promotes Endothelial Dysfunction in Ventilator‐Induced Lung Injury: Potential Treatment with Quercetin

open access: yesAdvanced Science, EarlyView.
Abnormal mechanical stretch induced by mechanical ventilation (MV) disrupts endothelial junctions via the NOX2/ROS/CaMKII/ERK1/2 axis both in human aortic endothelial cells (HAECs) in vitro and in ventilator‐induced lung injury (VILI) in mice. Quercetin, an antioxidant predicted to bind to NOX2, can effectively prevent mechanical stretch‐induced ...

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

open access: yesMass Spectrometry Reviews, EarlyView., 2023
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.
