background: recently, the anti cancer effect of chromene derivatives in different cell types has been reported. in this study, we report some derivatives of dihydropyrano[c]chromenes with growth inhibitory and apoptotic activity against k562, chronic myeloid leukaemia (cml). methods: the cells were seeded in 96-well plates at 1×105 cells/well and treated with different concentrations of the dih...

Ligation of major histocompatability complex class I (MHC-I) molecules expressed on T cells leads to both growth arrest and apoptosis. The aim of the current study was to investigate the intracellular signal pathways that mediate these effects. MHC-I ligation of human Jurkat T cells induced a morphologically distinct form of apoptosis within 6 h. A specific caspase inhibitor, which inhibited Fa...

Many tumors overexpress members of the inhibitor of apoptosis protein (IAP) family. IAPs contribute to tumor cell apoptosis resistance by the inhibition of caspases, and are degraded by the proteasome to allow further progression of apoptosis. Here we show that tumor cells can alter the specificity of cytosolic proteolysis in order to acquire apoptosis resistance, which promotes formation of ra...

The phosphorylation state of Retinoblastoma protein (Rb) plays a role in cell proliferation and apoptosis. Within cells, cyclin dependent kinases (cdks) phosphorylate Rb in response to growth stimulatory signals, whereas protein phosphatase 1 (PP1) dephosphorylates Rb when cells stop proliferating or undergo apoptosis in response to anti-proliferative or stress signals. Stimulation of PP1 activ...

Mometasone furoate (MF) is a kind of glucocorticoid with extensive pharmacological actions, including inhibiting tumor progression; however, the role MF in head and neck squamous cell carcinoma (HNSCC) still unclear. This study aimed to evaluate inhibitory effect against HNSCC investigate its underlying mechanisms. Cell viability, colony formation, cycle apoptosis were analyzed explore on cells...


 Purpose: Breast cancer has over the years been one of major acute carcinomas in women. This study investigated fundamental mechanistic functions lncRNA-NEAT1/miR-148a-3p/Wnt/β-catenin axis moderating cell viability, apoptosis and autophagy Cancer (BC).
 Methods: RT-qPCR measured expression lncRNA NEAT1 microRNA-148a-3p human lines for Cancer. Cell transfection upregulated or silence...

Acute erythroleukemia is a rare form of acute myeloid leukemia recognized by its distinct phenotypic attribute erythroblasts proliferation. In this study, in vitro experiments showed that newly synthesized chalcone (ZH-254) inhibited cell proliferation, caused apoptosis, arrested the cycle G1 phase, and downregulated Fli-1 expression inhibiting promoter activity. vivo ZH-254 could effectively a...

Parkinson's disease is a degenerative disorder of the central nervous system. The motor symptoms of Parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain the cause of this cell death is unknown. Homocysteine (Hcy) is a non-protein amino acid. It is a homologue of the amino acid cysteine. The elevated levels of homocysteine in p...

In a systematic effort to identify a potent antiproliferative agent, four complexes of vanadium containing maltol and deferiprone ligands were synthesized and evaluated for their cytotoxic activity against five human and animal cancer cell lines, including human breast cancer cells (MCF-7), human cervix epithelial carcinoma (HeLa), human colon cancer cell line (HT-29), human leukemia cell line ...

Objective(s):Hypoxia induces cellular oxidative stress that is associated with neurodegenerative diseases. Here, the protective effects of ferulic acid (FA) on hypoxia-induced neurotoxicity in PC12 cells were evaluated. Materials and Methods:We investigated the effect of FA on PC12 cells subjected to hypoxia stress, in vitro. Results:FA increased cell viability, prevented membrane damage (LDH r...
