Targeting apoptosis by 1,2-diazole through regulation of EGFR, Bcl-2 and CDK-2 mediated signaling pathway in human non-small cell lung carcinoma A549 cells

Lung cancer is the leading cause of cancer deaths worldwide and non-small cell lung carcinoma (NSCLC), a heterogeneous class of tumors, represents approximately 85% of all new lung cancer diagnosis. Conventional treatment options have limited efficacy because most cases are in the advanced stage at the time of diagnosis. The present study evaluates the anti-cancer activity of 1,2-diazole (pyrazole), a natural compound from mangrove plant Rhizophora apiculata (R.apiculata) on A549 lung carcinoma cells. In the present study the anti-cancer mechanism of pyrazole, was examined by the expression level of proteins Epidermal growth factor receptor (EGFR), Bcl-2-associated X protein (Bax), B-cell lymphoma-2 (Bcl-2) and Cyclin-dependent kinase-2 (CDK-2) which are commonly associated with the cell signaling pathways that control cell survival and apoptosis, that could facilitate to develop a novel target and effective treatment approach for patients with NSCLC. Pyrazole significantly induced cell cycle arrest and initiated apoptosis through inhibition of downstream components of EGFR tyrosine kinase pathway. Pyrazole disrupts the mitochondrial membrane potential and modulated the protein levels of Bax and Bcl-2 which could probably lead ...Continue Reading

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Cell Cycle Pathways

Cell cycle is a complex process regulated by several signal transduction pathways and enzymes. Here is the latest research on regulation of cell cycle and cell cycle pathways.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.


Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
