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.

5631- BCA,    Perspectives Regarding the Role of Biochanin A in Humans
- Review, Var, NA - Review, AD, NA
*BioAv↓, Biochanin A (BCA) is an isoflavone mainly found in red clover with poor solubility and oral absorption
*Inflam↓, various effects, including anti-inflammatory, estrogen-like, and glucose and lipid metabolism modulatory activity, as well as cancer preventive, neuroprotective, and drug interaction effects.
AntiCan↑,
*neuroP↑, many studies have focused on the effect of BCA on neurodegenerative diseases, especially PD and AD
chemoPv↑, BCA Has Chemopreventive Activity Against Various Cancers
Dose↝, BCA is metabolized in the gut to GEN or formononetin, which is converted to daidzein and then to equol (Knight and Eden, 1996).
*SOD↑, BCA also has a gastroprotective effect through the enhancement of cellular metabolic cycles, as evidenced by increases in superoxide dismutase (SOD) and nitric oxide (NO) activity, decreases in the malondialdehyde (MDA) and Bax levels, and increases
*MDA↓,
*BAX↓,
*HSP70/HSPA5↑, and increases in Hsp70 expression
*AntiDiabetic↑, BCA is well known for its antidiabetic and hypolipidemic effects.
*Insulin↑, BCA increases the circulating insulin levels and improves insulin sensitivity, leading to body weight control, an increase in liver glycogen, and a decrease in plasma glucose
*TNF-α↓, BCA inhibits the production of inflammatory mediators, such as TNF-α, interleukin-1β (IL-1β), IL-6, iNOS, COX-2, MMP-9, and NO, in various inflammatory responses
*IL1β↓,
*IL6↓,
*iNOS↓,
*COX2/PTGS2↓,
*MMP9↓,
*ROS↓, BCA scavenges ROS and increases SOD activity
*PGE2↓, BCA significantly reduces the synthesis of prostaglandin E2 and/or thromboxane B2 by inhibiting COX-2 expression
*BACE/β-secretase↓, BCA effectively inhibits the activity of beta-site amyloid precursor protein cleaving enzyme 1 (BACE1)
*BioAv↑, Various attempts have been made to improve the solubility and bioavailability of BCA, including the use of liposomes
P-gp/ABCB1⇅, Interestingly, BCA has been found to stimulate P-gp in some studies (An and Morris, 2010). Therefore, the effect of BCA on P-gp may be substrate dependent.
