Cytoskeletal Dynamics in Cancer: From Pathogenesis to Treatment

MedComm, Volume 7, Issue 10, October 2026.
This review systematically addresses the fundamental roles of the cytoskeleton (actin filaments, microtubules, and intermediate filaments) in cancer progression. We focus on how cytoskeletal dynamics regulate tumor proliferation, metastasis, and programmed cell death, while also modulating the immune microenvironment. Understanding these mechanisms may

Radiotherapy‐Induced Side Effects: Epidemiology, Pathogenesis, Prevention and Treatments

MedComm, Volume 7, Issue 10, October 2026.
Radiotherapy for malignancies frequently injures the organs’ systems through oxidative stress, fibrosis, inflammation, and vascular damage. This review systematically maps the epidemiology, pathogenesis, and emerging therapies to propose a mechanism‑network‑targeted framework for integrated, personalized care in radiation oncology.

Sequence Inversion Dictates the Antiproliferative Activity of Bidirectional Tryptophan‐Containing Dipeptide Libraries

Journal of Peptide Science, Volume 32, Issue 10, October 2026.
Reversing the peptide backbone sequence of novel tryptophyl‐dipeptides uncovers profound changes in synthetic accessibility and antineoplastic profiles against human solid tumors. Phenotypic screening identifies a conformationally restricted lead architecture that achieves sub‐micromolar growth inhibition, confirming sequence topology as a critical ...

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.
