MKP1 Cancer Research Results

MKP1, MAP kinase phosphatase 1: Click to Expand ⟱
Source:
Type:
MKP-1 and MKP-2 belong to the dual-specificity phosphatase family and are key regulators of MAPK signaling pathways (including ERK, JNK, and p38), which are central to cell proliferation, differentiation, and apoptosis.
-By dephosphorylating MAPKs, these phosphatases help maintain signaling homeostasis and protect cells against excessive or prolonged MAPK activation that could lead to cell death or uncontrolled proliferation.

-MKP-1 is frequently upregulated in various cancers, including breast, lung, and ovarian cancers, where it may serve as a feedback inhibitor of MAPK pathways.
- In some studies, high MKP-1 levels have been linked to resistance to chemotherapy and radiotherapy, as enhanced deactivation of MAPKs can reduce apoptosis in response to treatment-induced stress.

selectivity∅, Plumbagin induced cell death in EL4(normal) cells and Jurkat cells
tumCV↑, cell viability dramatically decreased with increasing concentrations of plumbagin (0.05-2.5uM) when incubated for 24 or 48 h
Cyt‑c↑, Bax dependent cytochrome c release and apoptosome complex formation is followed by the cleavage of pro-caspase-3
Casp3↑,
GSH/GSSG↓, progressive decrease in GSH/GSSG ratio in tumor cells following plumbagin treatment
ROS↑, simultaneous increase in the levels of intracellular ROS was observed in both these cell lines which remained high up to 4 h indicating an increase in oxidative stress in tumor cells
mt-ROS↑, While we observed low basal mtROS levels in untreated cells, plumbagin treatment resulted in a significant increase in mtROS levels
*ROS↑, both cell lines, meaning normal EL4 cells too
eff↓, NAC, GSH and PEG-catalase were able to abrogate plumbagin induced ROS and cell death.

- Review, Var, NA
ROS↑, Various studies have shown that plumbagin is a potent inducer of ROS
TrxR↓, The mechanism underlying ROS induction by plumbagin has predominantly been attributed to inhibition of the antioxidant enzymes TrxR
