Effects of a Novel COL4A3 Homozygous/Heterozygous Splicing Mutation on the Mild Phenotype in a Family With Autosomal Recessive Alport Syndrome and a Literature Review.

Background: Alport syndrome involves chronic progressive kidney failure and extrarenal organ damage caused by COL4A3, COL4A4, and COL4A5 mutations.

Methods: We initially discerned a COL4A3 splicing mutation via next-generation sequencing. Next, we used bioinformatics, renal biopsy pathology, and an in vitro minigene experiment.

Klotho inhibits renal ox-LDL deposition via IGF-1R/RAC1/OLR1 signaling to ameliorate podocyte injury in diabetic kidney disease.

Objective: Diabetic kidney disease (DKD) is characterized by the abnormal deposition of oxidized low-density lipoprotein (ox-LDL), which contributes to podocyte damage. Klotho, an aging suppressor that plays a critical role in protecting podocytes in DKD, is mainly expressed in kidney tubular epithelium and secreted in the blood. However, it has not been established whether Klotho can alleviate podocyte injury by inhibiting renal ox-LDL deposition, and the potential molecular mechanisms require further investigation.

The UDPase ENTPD5 regulates ER stress-associated renal injury by mediating protein N-glycosylation.

Impaired protein N-glycosylation leads to the endoplasmic reticulum (ER) stress, which triggers adaptive survival or maladaptive apoptosis in renal tubules in diabetic kidney disease (DKD). Therapeutic strategies targeting ER stress are promising for the treatment of DKD. Here, we report a previously unappreciated role played by ENTPD5 in alleviating renal injury by mediating ER stress.

T1AM Attenuates the Hypoxia/Reoxygenation-Induced Necroptosis of H9C2 Cardiomyocytes via RIPK1/RIPK3 Pathway.

Purpose: To investigate the detailed mechanism of 3-iodothyronamine (T1AM) in cell apoptosis and programmed necrosis of hypoxia/reoxygenation- (H/R-) induced H9C2 injury.

Materials And Methods: Cardiomyocyte H9C2 cells were cultured in vitro for the establishment of cardiomyocyte H/R models. Cells were randomly divided into four groups: the control group, H/R group, T1AM pretreatment group, T1AM pretreatment and H/R (6 m T1AM+H/R) group.

Serum exosomal microRNAs as predictive markers for EGFR mutations in non-small-cell lung cancer.

Background: Current therapeutic drugs show positive effects on non-small-cell lung cancer (NSCLC) patients with mutant epidermal growth factor receptor (EGFR) expression, whereas a lesser beneficial effect is generally noted on NSCLC patients with wild-type EGFR. Therefore, identification of new detection methods for the accurate clinical diagnosis of NSCLC is essential.

Methods: In this study, tumor-derived exosomes from the plasma of EGFR mutation and wild-type NSCLC patients were isolated.

Ganoderic acid DM induces autophagic apoptosis in non-small cell lung cancer cells by inhibiting the PI3K/Akt/mTOR activity.

The incidence and mortality of lung cancer are the highest among cancer-related deaths. However, the long-term use of currently available cytotoxic drugs can increase genetic alterations in cancer cells and cause drug-resistance, which significantly limits their usage. Since current systemic treatment options are limited, effective chemotherapeutic agents are urgently needed for non-small cell lung cancer (NSCLC) treatment.

Relationship of SOCS3 and TGF-β with IDO expression in early pregnancy chorionic villi and decidua.

We aimed to investigate the expression of suppressors cytokine signaling (SOCS)-3, transforming growth factor (TGF)-β and indoleamine 2,3-dioxygense (IDO) and to analyse the relationship of SOCS3 and TGF-β with IDO expression in early pregnancy chorionic villi and decidua in the maternal-fetal interface. Western blot analysis and immunohistochemical method were used to detect the expression of TGF-β, SOCS3 and IDO in chorionic villi and decidua tissues of normal pregnant women. SOCS3, TGF-β and IDO protein was identified in chorionic villi and decidua tissues of normal pregnant women and there was a negative correlation between the expression of IDO and SOCS3, but TGF-β expression was positively correlated with IDO expression.
