Abstract

Deltamethrin (DLM) is an α-cyano type-II synthetic pyrethroid compound which is extensively used in different agricultural and home pest control. The advantages of pyrethroids over other insecticides are that they are relatively non-toxic to birds and mammals and show high efficacy at relatively lower concentrations. DLM may have dual characteristics i.e. at low molar-concentration, it is nontoxic to normal healthy cells but can induce apoptotic cell death in cancerous cells. There is no reported work based on such hypothesis. Thus, this study has been designed to explore the anticancer property of DLM and the mechanism behind the apoptotic cell death by DLM in cancer cell line (Jurkat J6). Molecular docking study indicates that DLM has the greater binding affinity towards MCL-1 receptor. MTT assay has revealed some significant loss in the viability of cancerous cells by DLM. Further estimation of ROS and GSH have shown the significant oxidative stress induced by DLM in concentration-time dependent manner. DLM has also increased the caspase-3 activity and the apoptotic cells significantly while a decrease in interleukin-2 level has also been observed. The pre-treatment with thiol antioxidant and caspase inhibitor has confirmed ...Continue Reading

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

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

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.
