Connexin 43 regulates pyroptosis by influencing intracellular calcium levels in X-ray induced vascular endothelial cell damage.

Objective: Our prior research has established that X-ray exposure induces pyroptosis in human umbilical vein endothelial cells (HUVECs), with Cx43 playing a regulatory role in this process. However, the precise mechanism by which Cx43 regulates pyroptosis remains unclear. The objective of this study is to assess the involvement of the calcium signaling pathway in Cx43-mediated regulation of X-ray-induced pyroptosis in HUVECs.

Ethnopharmacological Relevance: Baiheqingjin Decoction (BHQJ), which consists of 7 traditional Chinese herbs including Baibu (Stemona tuberosa Lour.), Hezi (Terminalia chebula Retz.), Mahuang (Ephedra sinica Stapf.

Cellular Metabolism of Fluorescent Nanoprobes Formed by Self-Assembly of Amphiphiles: Dynamic Trafficking from the Golgi Apparatus to the Lysosome.

Dynamic trafficking of foreign substances (organic molecules) in eukaryotic cells is closely correlated to the metabolism of cells; however, it is to date not fully understood due to the lack of suitable probes. In the present study, we employed an amphiphilic probe (i.e.

The protective effects of Bacillus licheniformis preparation on gastrointestinal disorders and inflammation induced by radiotherapy in pediatric patients with central nervous system tumor.

Purpose: we studied the effect of Bacillus licheniformis preparation (ZCS) on CNST (central nervous system tumor) patients undergoing the gastrointestinal symptoms and inflammation induced by radiotherapy.

Materials And Methods: 160 CNST patients with craniospinal irradiation (CSI) treatment were divided into experiment and control group. The experiment group patients took one capsule per time of ZCS and three times a day until the end of radiotherapy, starting one day before radiotherapy.

Clusterin and neuropilin-2 as potential biomarkers of tumor progression in benzo[a]pyrene-transformed 16HBE cells xenografted nude mouse model.

Benzo[a]pyrene (BaP) is a ubiquitous environment contaminant and its exposure could increase incidence of human lung cancer. In order to confirm and compare potential biomarkers of BaP-induce carcinogenesis and tumor progression, time-dependent changes of clusterin (CLU) and neuropilin-2 (NRP2) levels were evaluated in sera of BaP-transformed 16HBE cell line T-16HBE-C1 cells xenografted nude mice. Performance of CLU and NRP2 on tissue classification and tumor progression forecast was also calculated.

Antiproliferation of berberine is mediated by epigenetic modification of constitutive androstane receptor (CAR) metabolic pathway in hepatoma cells.

Constitutive androstane receptor (CAR) regulates hepatic xenobiotic and energy metabolism, as well as promotes cell growth and hepatocarcinogenesis. Berberine is an ancient multipotent alkaloid drug which derived from Coptis chinensis plants. Here we report that berberine is able to be cellular uptake and accessible to chromatin in human hepatoma HepG2 cells.

Label-free quantitative proteomic analysis of benzo(a)pyrene-transformed 16HBE cells serum-free culture supernatant and xenografted nude mice sera.

To screen potential biomarkers of benzo(a)pyrene (BaP)-induced lung cancer, the proteomic profiles of BaP-transformed 16HBE cell line T-16HBE-C1 cells serum-free culture supernatant and xenografted nude mice sera were compared with those of 16HBE group by utilizing label-free quantitative proteomic strategy. By employing nano-LC-MS/MS technology followed by MaxQuant and Perseus processing, 489 differentially expressed proteins were identified between T-16HBE-C1 and 16HBE cells serum-free culture supernatant, and 49 significantly up-regulated proteins were identified in T-16HBE-C1 xenografted nude mice sera. Three proteins neuropilin-2 (NRP2), clusterin (CLU) and A-kinase anchor protein 12 (AKAP12) were up-regulated in the serum-free culture supernatant of T-16HBE-C1 cells.

Changes of sulfur dioxide, nuclear factor-κB, and interleukin-8 levels in pediatric acute lymphoblastic leukemia with bacterial inflammation.

Background: Bacterial inflammation is a common complication in patients with leukemia, and sulfur dioxide (SO2) is a bioactive molecule in modulating Gram-negative bacilli infection. This study aimed to examine the changes in SO2, nuclear factor-κB (NF-κB), and interleukin-8 (IL-8) levels in pediatric acute lymphoblastic leukemia (ALL) with Gram-negative bacterial inflammation.

Methods: Fifty-five ALL children were enrolled in this study, including 30 males and 25 females, aged 3-13 years, and the median age was 7.

Immune regulation of hydrogen sulfide in children with acute lymphoblastic leukemia.

Background: Acute lymphoblastic leukemia (ALL) and chemotherapy can cause immune imbalance, and gaseous molecule hydrogen sulfide (H2S) can participate in the process of immune response. This study aimed to investigate the immune regulation of H2S in pediatric ALL.

Methods: Children (n = 78) with ALL admitted during 2010-2013 were included in this study.

The cell cycle distribution should be given more consideration in cell-based in vitro toxicological studies.

In this study, to discuss the importance of the cell cycle distribution in cell-based in vitro toxicity mechanism studies, diethyl sulfate (DES) was selected as a model chemical that induced the alteration of the cell cycle distribution in human bronchial epithelial cell line 16HBE 14o- (HBE) cells. Cells were treated with various concentrations of DES, cell proliferation and apoptosis were then determined. The results showed that DES concentration-dependently inhibited HBE cells proliferation and induced apoptosis.

Diethyl sulfate-induced cell cycle arrest and apoptosis in human bronchial epithelial 16HBE cells.

In this study, we investigated the effects of diethyl sulfate (DES) on cell proliferation, cell cycle progression and apoptosis in human bronchial epithelial 16HBE cells. Cells were treated with various doses of DES (0, 0.5, 1.
