Thymoquinone Inhibits Renal Cell Cancer Metastasis Through AMPK/mTOR-Mediated Autophagy

Key Findings Primary Discovery: Thymoquinone (TQ), extracted from Nigella sativa seeds, effectively inhibits renal cell carcinoma (RCC) metastasis by inducing autophagy through the AMPK/mTOR signaling pathway. Mechanism of Action: TQ activates AMPK phosphorylation while decreasing mTOR phosphorylation, leading to autophagy induction that subsequently inhibits cancer cell migration, invasion, and epithelial-mesenchymal transition (EMT). Experimental Results Cell […]

Berberine Extends Healthspan and Delays Neurodegeneration via ROS-PMK-1/SKN-1 Pathway

Key Findings Lifespan Extension: Berberine significantly extended lifespan in C. elegans at concentrations of 1μM (19% increase), 10μM (28% increase), and 100μM (18% increase), with 10μM showing optimal effects. Healthspan Improvements: At 10μM, berberine reduced age pigments (lipofuscin accumulation), increased locomotory ability (body bends per minute), and maintained fertility unchanged compared to controls.

17α-Estradiol Preferentially Protects APOE4 Male Mice Against Aging

Main Finding The longevity drug 17α-estradiol (17αE2) provides greater protection against aging-related decline in male mice carrying the APOE4 gene variant compared to APOE3 mice. APOE4 is associated with shorter lifespan and higher Alzheimer’s disease risk, but 17αE2 treatment largely reverses these negative effects.

IL-11 Inhibition Extends Mouse Lifespan by 29%: A Breakthrough Rivaling Rapamycin’s Effects

TL;DR: A 2024 Nature study shows that inhibiting interleukin-11 (IL-11) extends median mouse lifespan by 28.7% when administered at an age equivalent to human late-50s, with improved health markers and reduced tumor incidence. This extension rivals that seen with rapamycin, raising questions about whether IL-11 inhibition works through similar or complementary mechanisms. Key Findings Lifespan
