GRP78 (Pgp, BiP or ERp72) is a central regulator of endoplasmic reticulum (ER) function due to its roles in protein folding and assembly, targeting misfolded protein for degradation, ER Ca(2+)-binding and controlling the activation of trans-membrane ER stress sensors.
-GRP78 protein, a marker for endoplasmic reticulum stress
-GRP78’s role as a master regulator of the unfolded protein response (UPR) and cellular stress responses
The association of P-gp and inhibition of cell death in cancerous cells has also been reported in several studies including in hepatocellular, colorectal, prostate cancer, and gastric cancer. Although counterintuitive due to its prominent role in cancer resistance, P-gp has been linked to favorable prognosis.
ERp72 can promote cancer cell proliferation, migration, and invasion by regulating various signaling pathways, including the PI3K/AKT and MAPK/ERK pathways. Additionally, ERp72 can also inhibit apoptosis (programmed cell death) in cancer cells, which can contribute to tumor progression. Overexpressed in: Breast, lung colorectal, prostrate, ovarian, pancreatic.

-GRP78 is frequently upregulated in a variety of solid tumors and hematological malignancies.
-Overexpression of GRP78 in cancer cells is often regarded as a marker of increased ER stress due to the reduced oxygen and nutrient supply typically encountered in the tumor microenvironment.
-Elevated GRP78 levels can contribute to tumor cell survival by enhancing the adaptive UPR, allowing cancer cells to cope with therapeutic and metabolic stress.

5591- BetA,    Advances and challenges in betulinic acid therapeutics and delivery systems for breast cancer prevention and treatment
- Review, BC, NA
BioAv↓, However, its poor water solubility limits its optimal therapeutic potential.
BioAv↑, nano-drug delivery systems (NDDSs) have gained significant attention as a method to substantially improve low solubility and poor drug bioavailability, enhance targeted drug delivery, and reduce side effects.
selectivity↑, reviews by Simone Fulda23,24 strengthened BA's potential for cancer treatment and prevention, particularly its ability to selectively trigger apoptosis in cancer cells while causing minimal harm to normal cells.
eff↑, It is important to note that the anticancer effects of BA on different types of tumors are more potent at a pH lower than 6.8.34

GRP78/BiP?, BA directly targets GRP78, triggering ER stress by activating the PERK-eIF2α-CHOP apoptotic cascade
ER Stress↑,
PERK↑,
CHOP↑,
ChemoSen↑, BA's ability to chemosensitize BC cells to taxanes highlights its importance in situations of drug resistance
SESN2↑, Under hypoxia, BA strongly increases SESN2 expression.
ROS↑, Reducing SESN2 levels enhances BA-induced ROS production, DNA damage, and radiosensitivity, while decreasing autophagic flux, indicating that SESN2-mediated autophagy serves as a protective adaptive response.68
MOMP↓, decreases the mitochondrial outer membrane potential (MOMP),
MAPK↑, This leads to the activation of p38 Mitogen-activated protein kinase (p38 MAPK), the release of cytochrome C, apoptosis-inducing factor (AIF),
Cyt‑c↑,
AIF↑,
STAT3↓, BA suppresses the signal transducer and activator of transcription (STAT) 3 signaling pathways
FAK↓, BA's inhibition of STAT3, as well as FAK, leads to decreased expression of MMPs and elevated TIMP-2, thereby impairing cancer cell migration and invasion
TIMP2↑,
TumCMig↓,
TumCI↓,
Sp1/3/4↓, Sp inhibition reduces cancer gene expression, inhibiting cancer cell growth.
TumCCA↑, It increases cell numbers in the G2/M phase, leading to cell cycle arrest.
DNAdam↑, causes DNA damage, thereby inhibiting the progression and invasion of cancer cells.
