Physiactisome: A New Nanovesicle Drug Containing Heat Shock Protein 60 for Treating Muscle Wasting and Cachexia.

2022

Currently, no commercially available drugs have the ability to reverse cachexia or counteract muscle wasting and the loss of lean mass. Here, we report the methodology used to develop Physiactisome—a conditioned medium released by heat shock protein 60 (Hsp60)—overexpressing C2C12 cell lines enriched with small and large extracellular vesicles. We also present evidence supporting its use in the treatment of cachexia. Briefly, we obtain a nanovesicle-based secretion by genetically modifying C2C12 cell lines with an Hsp60-overexpressing plasmid. The secretion is used to treat naïve C2C12 cell lines. Physiactisome activates the expression of PGC-1α isoform 1, which is di…

Extracellular Vesicles: Delivery Vehicles of Myokines

2019

Movement and regular physical activity are two important factors that help the human body prevent, reduce and treat different chronic diseases such as obesity, type 2 diabetes, heart diseases, hypertension, sarcopenia, cachexia and cancer. During exercise, several tissues release molecules into the blood stream, and are able to mediate beneficial effects throughout the whole body. In particular, contracting skeletal muscle cells have the capacity to communicate with other organs through the release of humoral factors that play an important role in the mechanisms of adaptation to physical exercise. These muscle-derived factors, today recognized as myokines, act as endocrine and paracrine hor…

Effects of Pleurotus eryngii var. eryngii in "in vitro" and "in vivo" cancerogenetic models

2018

Heat shock proteins (Hsps) are highly expressed in a variety of cancer types contributing to tumor cell propagation and protection against apoptosis [1]. The current anti-cancer therapy is not always target specific and often is associated with complications for patients, Therefore new effective, specific and less toxic therapeutic approaches are needed. Medicinal mushrooms have emerged as wonderful source of nutraceuticals, anti-oxidants, anticancer, prebiotic, anti-inflammatory, cardiovascular, anti-microbial, and anti-diabetic. The ongoing research projects are aimed to promote mushrooms as new generation ‘‘biotherapeutics’’[2]. The aim of this study was to evaluate whether the cold-wate…

Anti-cancer effects of Pleurotus eryngii var. eryngii: an in vitro and in vivo models focusing on Heat Shock Proteins

2017

Heat shock proteins (Hsps) are highly expressed in a variety of cancer cells and are essential to their survival contributing to tumor cell propagation, metastasis, and protection against apoptosis]. Cancer is a leading cause of death worldwide. The current anti-cancer drugs available in market are not target specific and pose several side-effects and complications in clinical management of various forms of cancer, which highlights the urgent need for novel effective and less-toxic therapeutic approaches. Medicinal mushrooms have emerged as wonderful source of nutraceuticals, anti-oxidants, anticancer, prebiotic, anti-inflammatory, cardiovascular, anti-microbial, and anti-diabetic. The ongo…
