Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system that inflammation, demyelination, oligodendrocyte loss, gliosis, axonal injury and neurodegeneration are the main histopathological hallmarks of the disease. Although MS was classically thought as a demyelinating disease, but axonal injury occurs commonly in acute inflammatory lesions. In MS mi...

Increasing evidence suggests a role for apoptosis in the maintenance of the alveolar epithelium under normal and pathological conditions. However, the signaling pathways modulating alveolar type II (AT II) cell apoptosis remain poorly defined. Here we investigated the role of lysosomes as modulators of oxidant-mediated AT II cell apoptosis using an in vitro model of H(2)O(2)-stress. H(2)O(2) st...

BACKGROUND Fucoidan extract (FE), an enzymatically digested compound with a low molecular weight, is extracted from brown seaweed. As a natural compound with various actions, FE is attractive, especially in Asian countries, for improving the therapeutic efficacy and safety of cancer treatment. The present study was carried out to investigate the anti-tumor properties of FE in human carcinoma ce...

Apoptosis induced by fucoxanthin in HL-60 cells was associated with a loss of mitochondrial membrane potential at an early stage, but not with an increase in reactive oxygen species. Fucoxanthin treatment caused cleavages of procaspase-3 and poly (ADP-ribose) polymerase without any effect on the protein level of Bcl-2, Bcl-X(L), or Bax. Apoptosis induction by fucoxanthin may be mediated via mit...

Apoptosis is a fundamental process required for normal development of the nervous system and is triggered during neurodegenerative disease. To dissect the molecular events leading to neuronal cell death, we have developed a cell-free model of neuronal apoptosis. The model faithfully reproduces key elements of apoptosis, including chromatin condensation, DNA fragmentation, caspase activation/pro...

Pemetrexed is a multitargeted antifolate used for the treatment of malignant mesothelioma and non-small cell lung cancer (NSCLC). However, the mechanism by which pemetrexed induces apoptosis remains unclear. In the present study, we investigated the involvement of reactive oxygen species (ROS) and sirtuin 1 (SIRT1) in pemetrexed-induced apoptosis in MSTO-211 malignant mesothelioma cells and A54...

Abstract Background and Aims The fatty acid binding proteins family of lipid chaperones (FABPs) mediate trafficking lipid-mediated metabolic pathways. Despite inhibition induced FABPs may be beneficial in kidney damage, their enrolment renal homeostasis remains elusive. Therefore, we approached this issue cultured tubular cells. Method FABP mRNA protein expression were evaluated C57/BL6 mice su...

Aim: The opening of mitochondrial permeability transition (mPT) pore is an important event in the execution mitochondrial-mediated apoptosis. Some bioactive compounds elicit their chemotherapeutic effects against tumor/cancer cells via induction Annona muricata, a medicinal plant, folklorically used treatment tumors and cancers. This study therefore aimed at investigating effect methanol stem b...

Deoxypodophyllotoxin (DPT) is a naturally occurring flavolignan isolated from Anthriscus sylvestris. Recently, it has been reported that DPT inhibits tubulin polymerization and induces G2/M cell cycle arrest followed by apoptosis through multiple cellular processes. Despite these findings, details regarding the cellular and molecular mechanisms underlying the DPT-mediated cell death have been p...

Diabetes and its complications, such as delayed wound healing, are increasing at an alarming rate in India, putting enormous strain on the country’s limited healthcare resources. Hence, present study proposes to screen/identify possible mechanisms effect of flavonoid-enriched fraction Selaginella bryopteris extract against human keratinocyte cell lines (HaCaT) streptozocin (STZ)-induced diabeti...
