Move beyond free radical theory of aging

iMetaOmics, Volume 3, Issue 1, March 2026.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

A Novel Peptide, HS1002, Enhances Antitumor Activity via Dual Targeting of the GnRH Receptor and Human Telomerase Reverse Transcriptase in Prostate Cancer Cells

MedComm, Volume 7, Issue 3, March 2026.
HS1002, a new peptide targeting GnRHR and hTERT, demonstrates significant Anticancer activity in prostate cancer cells. The mechanism of HS1002 can be attributed to the reduction of serum testosterone levels by desensitization of GnRHR, the downregulation of hTERT expression and telomerase activity, and the enhancement of Anticancer immunity.

Chromatin Accessibility in Cancer: Biological Functions, Mechanisms, Therapeutic Potential, and Future Directions

MedComm, Volume 7, Issue 3, March 2026.
Cancer remains the leading cause of mortality worldwide, and drug resistance further underscores the urgent need for innovative therapeutic strategies. Chromatin, a stable yet highly dynamic nucleoprotein complex, serves as the primary carrier of genetic material in eukaryotic cells.

Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.
