Type:
P-glycoprotein (P-gp), also known as multidrug resistance protein 1 (MDR1), is a membrane protein that plays a crucial role in the transport of various substances across cellular membranes. It is part of the ATP-binding cassette (ABC) transporter family.
P-glycoprotein is often overexpressed in a variety of cancers, including breast cancer, lung cancer, leukemia, and ovarian cancer.

- The overexpression of P-glycoprotein (P-gp), is widely considered as an important reason for the MDR (multidrug resistance).

ABCB1 - ATP-Binding Cassette Subfamily B Member 1 / P-Glycoprotein

Abbreviation: ABCB1, P-gp, P-glycoprotein, MDR1

Type: ATP-dependent membrane efflux transporter / multidrug resistance protein

Function: ABCB1 encodes P-glycoprotein, an ATP-binding cassette transporter that exports a broad range of drugs, xenobiotics, lipids, and other substrates across cellular membranes. It is highly expressed in barrier tissues including the intestine, liver, kidney, placenta, and blood-brain barrier, where it limits tissue accumulation of potentially harmful compounds.

Cancer: ↑ Frequently overexpressed or functionally activated in drug-resistant tumors. Increased ABCB1 lowers intracellular concentrations of many anticancer agents by actively transporting them out of cancer cells, producing multidrug resistance and reducing chemotherapy effectiveness.

Alzheimer's Disease: ↓ Reduced ABCB1/P-glycoprotein expression or transport activity at the blood-brain barrier is associated with impaired amyloid-β clearance from the brain. Lower P-gp function correlates with increased cerebral Aβ accumulation and may contribute to Alzheimer's disease progression.

Prostate Cancer: Alterations in genes such as ERG, SPOP, MYC, androgen receptor (AR), and CHD1, drive PCa progression.
TP53 is the most commonly mutated gene in human cancer.
HH↑, GLI-1↑, SHH↑ P53↓
The loss of p53 and/or other tumor suppressor genes, reduced capacity for DNA repair, the dysfunction of telomerase activity, and changes in the pathways that govern the growth of cells also mediate the progression of Pca.
It has been well documented that Ca2+ influx and MDR1 upregulation are highly associated with GEM metabolism in human pancreatic carcinoma.
Increased Growth factor IGF-1/IGF-1R axis activation mediated by both PI3K/Akt or RAF/MEK/ERK system and AR expression remains important in the development and progression of prostate cancer.
It has been demonstrated that prostate cancer cells are relatively sensitive to heat stress.
Long non-coding RNA MALAT1 has been reported as an oncogenic target in multiple types of cancers, including PC.
