Article Abstract

Objective: To evaluate the therapeutic potential of the curcumin analog J7 in protecting the liver and regulating glucose and lipid metabolism in rats with type 2 diabetes.

Methods: Bioinformatics methods were used to identify signaling pathways linked to diabetic liver disease. Diabetic rats were treated with curcumin, low-dose J7, or high-dose J7, and liver function and fibrosis were assessed through biochemical analyses, histopathology, immunohistochemistry, and ELISA.

Results: J7 administration significantly improved lisver function, reduced fibrosis, and regulated metabolic profiles in diabetic rats. J7 downregulated TGF-β1, NF-κB p65, and BAX, while upregulating BCL-2, showing superior effects to traditional curcumin in reducing TGF-β1 and inhibiting α-SMA expression.

Conclusion: J7 demonstrates potential as a therapeutic agent for managing liver complications in type 2 diabetes, effectively attenuating liver fibrosis and regulating metabolism through the modulation of key signaling pathways and proteins.

Targeting NLRP3 inflammasome with curcumin: mechanisms and therapeutic promise in chronic inflammation.

Inflammopharmacology

The NOD‑like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a key molecular complex that amplifies inflammatory cascades by maturing interleukin‑1 beta (IL-1β) and interleukin‑18 (IL-18) and inducing pyroptosis. It serves as a major driver and co-driver of numerous diseases associated with chronic inflammation. Dysregulated NLRP3 activation contributes to the progression of disorders such as rheumatoid arthritis, inflammatory bowel disease, neurodegenerative diseases and atherosclerosis.

Turmeric (Curcuma longa) exhibits anti-obesity properties, yet its low water solubility limits bioavailability. In this study, a water-dispersible turmeric rhizome extract (WDTE) was developed using nano-dispersion technology with maltodextrin as a wall material and characterized by UPLC-QTOF-MS, dynamic light scattering, and zeta potential analysis. The WDTE contained 10 identified metabolites, including five diarylheptanoids such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin quantified at 7.

Background: Standard treatment for glioblastoma includes chemotherapy, alkylating agents such as temozolomide (TMZ); however, MGMT resistance leads to recurrence. Demethoxycurcumin (DMC) has been reported to inhibit cancer cell growth, induce apoptosis, and prevent metastasis in different cancer models. We investigated the DMC-induced apoptosis and autophagy via inhibition of the AKT/mTOR pathway in human glioma U87MG and T98G cell lines.

Background: Neuropathic pain profoundly affects the quality of life of patients and requires considerable medical resources. Extensive evidence indicates that neuroinflammation within the spinal cord plays a critical role in modulating neuropathic pain. Curcumin, renowned for its anti-inflammatory properties, has shown potential in alleviating neuropathic pain.

Hepatocellular carcinoma (HCC) is a common liver cancer often diagnosed at an advanced stage. While chemotherapies such as sorafenib is effective for some patients, others show poor responses, necessitating new treatments. Overexpression of MYCN/NCYM was recently shown to contribute to the development of HCC.
