Abstract

Chemotherapy options for advanced endometrial cancer are limited and newer therapeutic agents are urgently needed. This study describes the therapeutic potential of 7 Methyl-indole ethyl isothiocyanate (7Me-IEITC) in endometrial cancer cell lines. 7Me-IEITC was synthesized in our laboratory. The cell viability of 7Me-IEITC treated ECC-1 and KLE endometrial cancer cell was determined by MTS assay. Morphology and apoptosis were further confirmed by DAPI-staining and TUNEL assay. The measurement of reactive oxygen species (ROS), mitochondrial transmembrane depolarization potential (ΔΨm) and cell cycle phase was determined by FACS analysis. Expression of proteins involved in apoptosis, survival and cell-cycle progression was analyzed by Western blotting. 7Me-IEITC reduced the viability of the ECC-1 and KLE cancer cell-lines (IC(50)~2.5-10 μM) in a dose dependent fashion. 7Me-IEITC treatment caused mitochondrial transmembrane potential reduction, elevated the production of ROS, leading to activation of apoptosis in endometrial cancer KLE and ECC-1 cells. 7Me-IEITC treatment activated Bad, suppressed Bcl2 phosphorylation followed by PARP-1 deactivation and caspase 3 and 7 activation. 7Me-IEITC treatment arrested the progression of KL...Continue Reading

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.

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 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.

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
