Role of Kruppel-like factor 4 in regulating inhibitor of apoptosis-stimulating protein of p53 in the progression of gastric cancer.

Gastric cancer (GC) remains one of the leading causes of cancer-associated mortality. The overexpression of inhibitor of apoptosis-stimulating protein of p53 (iASPP) has been detected in GC tissues but the function of iASPP in the viability of GC cells and its underlying molecular mechanism remains unknown. Kruppel-like factor 4 (KLF4) is a tumor suppressor gene in GC and it may interact with p53.

Inhibition of miR-182-5p protects cardiomyocytes from hypoxia-induced apoptosis by targeting CIAPIN1.

Myocardial infarction (MI), a type of ischemic heart disease, is generally accompanied by apoptosis of cardiomyocytes. MicroRNAs play the vital roles in the development and physiology of MI. Here, we established a downregulation model of miR-182-5p in H9c2 cells under hypoxic conditions to investigate the potential molecular mechanisms for miR-182-5p in hypoxia-induced cardiomyocyte apoptosis (HICA).

The hepatic ectonucleotide pyrophosphatase/phosphodiesterase 1 gene mRNA abundance is reduced by insulin and induced by dexamethasone.

Hormones regulate hepatic gene expressions to maintain metabolic homeostasis. Ectonucleotide pyrophosphatase/phosphodiesterase 1 has been thought to interfere with insulin signaling. To determine its potential role in the regulation of metabolism, we analyzed its gene (Enpp1) expression in the liver of rats experiencing fasting and refeeding cycles, and in primary rat hepatocytes and human hepatoma HepG2 cells treated with insulin and dexamethasone using northern blot and real-time PCR techniques.

Inhibition of Hes1 enhances lapatinib sensitivity in gastric cancer sphere-forming cells.

It has been considered that the neurogenic locus notch homolog protein (Notch) signaling pathway serves an essential role in cellular differentiation, proliferation and apoptosis. However, the function of the Notch signaling pathway in gastric cancer stem cells (GCSCs) and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) sensitivity remains unclear. The present study aimed to delineate the role of the Notch1 signaling pathway in GCSCs and lapatinib sensitivity.

Phosphatase and tensin homolog deleted on chromosome 10 degradation induced by NEDD4 promotes acquired erlotinib resistance in non-small-cell lung cancer.

Acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors, such as gefitinib and erlotinib, is a critical issue in the treatment of patients with epidermal growth factor receptor mutant-positive non-small-cell lung cancer. Recent evidence suggests that downregulation of gene of phosphatase and tensin homolog deleted on chromosome 10 plays an important role in acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors in various types of cancers, including lung cancer. It was reported that the E3 ubiquitin ligase neural precursor cell expressed developmentally downregulated gene (NEDD4) (also known as NEDD4-1) negatively regulated phosphatase and tensin homolog deleted on chromosome 10 protein levels through poly-ubiquitination and proteolysis in carcinomas of the prostate, lung, and bladder.

Capn4 promotes epithelial-mesenchymal transition in human melanoma cells through activation of the Wnt/β-catenin pathway.

Melanoma, as one of the most highly metastatic types of cancer, is resistant to current treatment methods, including popular targeted molecular therapy. Consequently, it is essential to develop a deeper understanding of the mechanisms involved in melanoma progression so that alternative treatments may be identified. To date, accumulating evidence supports the use of calpains, including calpain small subunit 1 (also known as Capn4 or CAPNS1), which affect cancer progression through many pathways, such as epithelial‑mesenchymal transition (EMT), the Wnt/β-catenin (β-catenin) and the nuclear factor κB (NF-κB) signaling pathways.

Silencing of ataxia-telangiectasia mutated by siRNA enhances the in vitro and in vivo radiosensitivity of glioma.

It is reported that high expression of the ataxia-telangiectasia mutated (ATM) gene is linked with radioresistance in glioma. We hypothesized that the radiosensitivity of this brain tumor is enhanced by silencing of the ATM gene. We transfected the glioma cell line U251 with the siRNA-ATMpuro (group A) lentivirus or the siRNA-HKpuro (group N, negative control) lentivirus before irradiation.

Gastric tumor-initiating CD44 cells and epithelial-mesenchymal transition are inhibited by γ-secretase inhibitor DAPT.

It has been proposed that the Notch signaling pathway may serve a pivotal role in cellular differentiation, proliferation and apoptosis. However, the function of Notch signaling in gastric cancer stem cells (GCSCs) is largely unknown. The present study aimed to delineate the role of the Notch1 pathway in GCSCs and during epithelial-mesenchymal transition (EMT).
