Gum arabic  (Synonyms: Arabic gum)

Gum Arabic is an orally active complex branched polysaccharide. Gum Arabic can be isolated from the Acacia senegal tree. Gum Arabic upregulates the expression of maturation markers (CD86, CD40, and CD54), promotes ERK1/2 phosphorylation, and inhibits Apoptosis. Gum Arabic exhibits antimalarial effects against Plasmodium berghei ANKA. Gum Arabic exhibits hepatoprotective, renal, and cardiovascular protective activities. Gum Arabic improves obesity. Gum Arabic is commonly used as a stabilizer and thickener. Gum Arabic can be used in the research of brain tumor imaging^{[1][2][3][4][5][6][7][8][9][10]}.

Gum arabic (0.5%; 24 h) upregulates the expression of maturation markers (CD86, MHCII, CD40, CD54) in mouse bone marrow-derived dendritic cells (DCs)^[6].

Gum arabic (100 g/L; p.o. via drinking water; 5 days) significantly reduces Acetaminophen (HY-66005)-induced hepatotoxicity in male Swiss albino mice^[1].
Gum arabic (2.5%-10.0%; p.o. via drinking water; 8 consecutive days) does not significantly alter the concentrations of free radical scavengers (GSH, AA, SOD) or lipid peroxidation in rats^[2].
Gum arabic (3-6 g/100 mL; p.o. via drinking water; 5 weeks) is not effective in reversing body weight decrease or reducing elevated creatinine and urea levels in rats with chronic renal failure (kidney remnant model)^[2].
Gum arabic (10%; p.o. via drinking water; starting 10 days before infection) slightly decreases parasitaemia and significantly extends the lifespan of SV129/J wild-type mice infected with Plasmodium berghei ANKA^[5].
Gum arabic (15% w/v; p.o. via drinking water; 4 weeks) mitigates Adenine-induced chronic kidney disease (CKD) in male CD1 mice by reducing duodenal inflammation, oxidative and nitrosative stress, and improving renal function (decreasing plasma urea, creatinine and urine albumin)^[8].
Gum arabic (15% w/v; p.o. via drinking water) ameliorates water-pipe smoke (WPS)-induced cardiovascular toxicity in C57BL/6 mice, including reducing thrombosis, lowering systolic blood pressure, inhibiting cardiac inflammation and oxidative stress, and preventing myocardial DNA damage and apoptosis ^[9].
Gum arabic (10% w/w; p.o. via diet; 12 weeks) suppresses high-fat diet-induced obesity in mice by reducing body weight, visceral adipose tissue (VAT) weight, blood glucose and plasma lipids (total cholesterol, LDL, VLDL), and regulating hepatic lipid metabolism-related genes^[10].
