Asparaginase like 1 (ASRGL1) protein belongs to the N‑terminal nucleophile group, cleaving the isoaspartyl‑dipeptides and L‑asparagine by adding water. It tends to be overexpressed in cancerous tumors including ovarian cancer and breast tumors. The present study assessed the potential ability of ASRGL1 as a molecular target in gene‑based cervical cancer treatment. The protein expression level of ASRGL1 was determined in paraffin‑embedded tumor specimen by immunohistochemistry. Additionally, in order to assess the activity of ASRGL1 during the process of cervical cancer cell multiplication, ASRGL1‑short hairpin (sh) RNA‑expressing lentivirus was established, which was used to infect SiHa cells...

The overexpression and hypersecretion of mucus is a hallmark of chronic pulmonary inflammatory disease. Mucin5AC (MUC5AC) is a major component of airway gel‑forming mucin. Members of the Unc13 (Munc13) protein family act as important activators of granule exocytosis from various types of mammalian cells. The present study aimed to determine the role of Munc13 family proteins in MUC5AC secretion via an in vitro study with BEAS‑2B and Calu‑3 cell lines. Reverse transcription‑quantitative polymerase chain reaction and western blotting indicated that stimulation of the cells with 100 nM human neutrophil elastase (hNE) for 1 h did not affect the expression of either unc13 homolog B (Munc13‑2) or unc13 homolog D (Munc13‑4), but immunofluorescence analysis demonstrated that hNE treatment was associated with the recruitment of Munc13‑4 to the plasma membrane...

Reactive oxygen species (ROS) serve an important role in glucose‑lipid metabolic regulation. In the present study, the results demonstrated that there was bidirectional regulation of insulin action in 3T3‑L1 adipocytes treated with ROS. Transient and acute ROS exposure improved insulin‑induced metabolic effects in 3T3‑L1 adipocytes. Hydrogen peroxide (H2O2), as a stable and diffusible ROS, diffused into adipocytes and altered intracellular redox homeostasis, resulting in oxidation and inactivation of phosphatase and tensin homologue deleted on chromosome 10 (PTEN)...

Glioblastoma multiforme (GBM) is one of the most lethal types of tumour, despite severe treatment methods. The Cancer Genome Atlas has categorised GBMs into proneural, neural, classical and mesenchymal subtypes; the mesenchymal subgroup has the worst prognosis. CXCR4 has been reported as selectively overexpressed in the mesenchymal subtype and positively associated with MES markers. However, to the best of our knowledge the underlying mechanisms regarding how CXCR4 may regulate mesenchymal GBM are still unknown...

Cardiac function is reduced following myocardial infarction (MI) due to myocardial injury and alterations in the viable non‑ischemic myocardium, a process known as cardiac remodeling. The current treatments available for patients with acute MI (AMI) reduce infarct size, preserve left ventricular (LV) function and improve survival; however, these treatments do not prevent remodeling, which can lead to heart failure. The aim of the present study was to investigate the effects of thyroid hormone (TH) treatment following MI in an in vivo rat model...

Bone marrow‑derived mesenchymal stem cells (BM‑MSCs) have been used in experimental research and clinical trials for heart function restoration and cardiomyocyte regeneration. However, due to a hostile microenvironment created by ischemia, hypoxia and pro‑inflammatory factors, the survival rate of implanted BM‑MSCs remains low. Therefore, strategies that can promote BM‑MSC survival and prevent apoptosis are required. Previous studies have reported that microRNA‑16 (miR‑16) can inhibit cell proliferation by targeting several proteins and signal pathway, not only by inducing apoptosis...
