Murill (ABM), a medicinal mushroom, has beneficial effects on various human metabolic diseases. The objective of this research was to evaluate the antioxidant and antidiabetic properties of ABM extracts (ethanol extract and ethyl acetate extract). The antioxidant activities of ABM ethanol extract (EE) and ethyl acetate extract (EA) were analyzed using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and hydroxyl radical scavenging assays and the reducing power using KFe(CN) in vitro. Moreover, the effects of EE and EA on α-glucosidase inhibitory activity and improving glucose uptake by HepG2 cells were investigated in vitro. The EA showed stronger antioxidant activity, as well as inhibition of α-glucosidase, compared to EE. The analysis of glucose uptake by HepG2 cells showed that EA had significant glucose-lowering activity and exhibited no difference compared to metformin. The results suggest that ABM extracts could improve the glucose uptake by HepG2 cells and thereby alleviate postprandial hyperglycemia. This investigation provides a strong rationale for further studies on the application of ABM to control type 2 diabetes.

Reduction of glucose transporter 1 (GLUT1), even deletion, may results in cartilage fibrosis and osteoarthritis. This study aims to investigate the SUMOylation of GLUT1 in osteoarthritis through small ubiquitin-like modifier 1(SUMO1), and explore the role of SUMOylated GLUT1 in glycometabolism, proliferation and apoptosis in chondrocytes. Human chondrocytes were incubated with 10 ng/mL of IL-1β to mimic osteoarthritis in vitro.

Background/objectives: Intrahepatic cholangiocarcinoma (iCCA) is a malignant liver tumor with a rising global incidence and poor prognosis, largely due to late-stage diagnosis and limited effective treatment options. Standard chemotherapy regimens, including cisplatin and gemcitabine, often fail because of the development of multidrug resistance (MDR), leaving patients with few alternative therapies. Doxycycline, a tetracycline antibiotic, has demonstrated antitumor effects across various cancers, influencing cancer cell viability, apoptosis, and stemness.

Abscisic acid (ABA) is a hormone with a long evolutionary history, dating back to the earliest living organisms, of which modern (ABA-producing) cyanobacteria are likely descendants, which existed long before the separation of the plant and animal kingdoms, with a conserved role as signals regulating cell responses to environmental challenges. In mammals, along with the anti-inflammatory and neuroprotective function of ABA, nanomolar ABA regulates the metabolic response to glucose availability by stimulating glucose uptake in skeletal muscle and adipose tissue via an insulin-independent mechanism and increasing metabolic energy production and also dissipation in brown and white adipocytes. Chronic ABA intake of micrograms per Kg body weight improves blood glucose, lipids, and morphometric parameters (waist circumference and body mass index) in borderline subjects for prediabetes and metabolic syndrome.

Adipose tissue, particularly white adipose tissue (WAT), plays a central role in energy storage and metabolic regulation. Excess WAT, especially visceral fat, is strongly linked to metabolic disorders such as obesity and type 2 diabetes. The browning of WAT, whereby white fat cells acquire characteristics of brown adipose tissue (BAT) with enhanced thermogenic capacity, represents a promising strategy to enhance metabolic health.

Catharanthus roseus leaves have been traditionally described to possess potent antidiabetic activity and some leaf-specific alkaloids, including vindoline, have been studied for their antidiabetic potential. The aim of the present study was to validate the antidiabetic property of the plant with special reference to vindoline. An Ayurveda-based method was used to prepare the Swaras [leaf juice extract (LJE)] of three familial C.
