Accurately identifying positive and negative regulation of apoptosis using fusion features and machine learning methods.

Apoptotic proteins play a crucial role in the apoptosis process, ensuring a balance between cell proliferation and death. Thus, further elucidating the regulatory mechanisms of apoptosis will enhance our understanding of their functions. However, the development of computational methods to accurately identify positive and negative regulation of apoptosis remains a significant challenge.

Chinese college students' help-seeking behavior: An application of the modified theory of planned behavior.

Chinese college students have a high incidence of psychological problems but rarely seek professional psychological help. Despite this fact, there have been few studies of the help-seeking behavior of Chinese college students with mental health problems. This research aims to use a modified model based on the theory of planned behavior (TPB) to explore the intentions and behaviors of Chinese college students with psychological problems in seeking professional psychological help.

Plin2-mediated lipid droplet mobilization accelerates exit from pluripotency by lipidomic remodeling and histone acetylation.

Metabolic switch is critical for cell fate determination through metabolic functions, epigenetic modifications, and gene expression. However, the mechanisms underlying these alterations and their functional roles remain unclear. Here, we show that Plin2-mediated moderate lipid hydrolysis is critical for pluripotency of embryonic stem cells (ESCs).

Cell HE staining smears and paired cell paraffin sections in detection of epithelial growth factor receptor gene of pleural fluid specimens.

Objectives: The advanced non-small cell lung cancer (NSCLC) patients with pleural effusion have no opportunity for surgery treatment. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are the first-line drugs for these patients with -sensitive mutation. However, the disease progression and drug update during or after treatment of EGFR-TKIs bring more challenges and puzzles to clinical diagnosis and treatment, which inevitably requires archived pleural cell samples for EGFR re-examination or comparative study.

MAP2K6 remodels chromatin and facilitates reprogramming by activating Gatad2b-phosphorylation dependent heterochromatin loosening.

Somatic cell reprogramming is an ideal model for studying epigenetic regulation as it undergoes dramatic chromatin remodeling. However, a role for phosphorylation signaling in chromatin protein modifications for reprogramming remains unclear. Here, we identified mitogen-activated protein kinase kinase 6 (Mkk6) as a chromatin relaxer and found that it could significantly enhance reprogramming.

Effect of tacrolimus on the expression of Park7 in glomerular podocytes injured by puromycin aminonucleoside.

Objectives: To study the effect of puromycin aminonucleoside (PAN) on the apoptosis of mouse podocyte clone 5 (MPC-5) and the expression of recombinant human Parkinson's disease 7 (Park7) and to study the protective mechanism of tacrolimus (FK506) against MPC-5 injury.

Methods: MPC-5 cells were cultured and then divided into three groups: blank control (control), PAN, and FK506. The cells in the PAN group were added with PAN (with a concentration of 50 mg/L) to establish a model of MPC-5 injury, and those in the FK506 group were added with PAN (with a concentration of 50 mg/L) and FK506 (with a concentration of 5 mg/L).

Effects of tacrolimus on autophagy protein LC3 in puromycin-damaged mouse podocytes.

Objective: To investigate the mechanism through which tacrolimus, often used to treat refractory nephropathy, protects against puromycin-induced podocyte injury.

Methods: An model of puromycin-induced podocyte injury was established by dividing podocytes into three groups: controls, puromycin only (PAN group), and puromycin plus tacrolimus (FK506 group). Podocyte morphology, number, apoptosis rate and microtubule associated protein 1 light chain 3 alpha () expression were compared.

Glis1 facilitates induction of pluripotency via an epigenome-metabolome-epigenome signalling cascade.

Somatic cell reprogramming provides insight into basic principles of cell fate determination, which remain poorly understood. Here we show that the transcription factor Glis1 induces multi-level epigenetic and metabolic remodelling in stem cells that facilitates the induction of pluripotency. We find that Glis1 enables reprogramming of senescent cells into pluripotent cells and improves genome stability.

Influence of tacrolimus on podocyte injury inducted by angiotensin II.

Objective: This study investigated the protective effect of FK506 in podocytes and the correlation of TRPC6 with podocyte injury repair.

Methods: MPC5 were cultured in vitro, parallel with the control group, an Ang II stimulation group, and an FK506 intervention group. The apoptosis rate with flow cytometry also detected TRPC6 mRNA and protein expression by RT-PCR and Western blot, and then observed the distribution of TRPC6 with indirect immunofluorescence labeling under confocal microscope.
