Palmitic acid (PA), a type of saturated fatty acids, induces cardiovascular diseases by causing cardiomyocyte apoptosis with unclear mechanisms. Akt participates in PA-induced cardiomyocyte apoptosis. GSK-3β is a substrate of Akt, we investigated its role in PA-induced apoptosis. We reveal that PA inhibits GSK-3β phosphorylation accompanied by inactivation of Akt in H9c2 cardiomyocytes. We also reveal...
V-set and transmembrane domain-containing 1 (VSTM1), which is downregulated in bone marrow cells from leukemia patients, may provide a diagnostic and treatment target. Here, a triple-regulated oncolytic adenovirus was constructed to carry a VSTM1 gene expression cassette, SG611-VSTM1, and contained the E1a gene with a 24-nucleotide deletion within the CR2 region under control of the human...
Protein phosphatase 2A is one of four major classes of serine/threonine phosphatases. Overexpression of brain-specific regulatory subunit PPP2R2 in neuron cells is implicated in pathogenesis. The alternative splicing of PPP2R2B encodes two isoforms. They are subunit of cytoplasmic specific Bβ1 and mitochondria-targeted Bβ2. The two constructs were transfected into human neuroblastoma cells, SK-N-SH,...
PDCD5 (programmed cell death 5) accelerates apoptosis of certain tumor cells and the replication-defective Ad-PDCD5 may be a promising agent for enhancing chemosensitivity. In this study, a triple-regulated conditionally replicating adenoviruses (CRAd) carrying PDCD5 gene expression cassette, SG611-PDCD5, was engineered. In SG611-PDCD5, the E1a gene with a deletion of 24 nucleotides within CR2 region...
Combined treatment modalities using tumor necrosis factor related apoptosis-inducing ligand L (TRAIL) and cytotoxic drugs revealed highly additive effects in some tumor cell lines. Little is known about the efficacy and underlying mechanistic effects of the modalities in chemoresistant tumor cells. The purpose of this study is to investigate the possible role of JNK in the synergistic effect in Doxorubicin...
