Objective: Anorexia nervosa (AN) is an eating disorder characterized by severe weight loss and associated with hyperactivity and circadian rhythm disruption. However, the cellular basis of circadian rhythm disruption is poorly understood. Glial cells in the suprachiasmatic nucleus (SCN), the principal circadian pacemaker, are involved in regulating circadian rhythms.

Macropinocytosis is a nonselective form of endocytosis that allows cancer cells to largely take up the extracellular fluid and its contents, including nutrients, growth factors, etc. We first elaborate meticulously on the process of macropinocytosis. Only by thoroughly understanding this entire process can we devise targeted strategies against it.

Patients with pathogenic variants in the gene suffer from severe and recurrent rhabdomyolysis episodes precipitated by fasting. Autophagy functioning was analyzed , in primary skeletal myoblasts from TANGO2 patients, in basal and fasting conditions, and mutations were associated with reduced LC3-II levels upon starvation. In zebrafish larvae, inhibition induced locomotor defects which were exacerbated by exposure to atorvastatin, a compound known to cause rhabdomyolysis.

In the clinic, Lipiodol chemotherapeutic emulsions remain a main choice for patients diagnosed with hepatocellular carcinoma (HCC) via the mini-invasive transarterial chemoembolization (TACE) therapy. However, the poor stability of conventional Lipiodol chemotherapeutic emulsions would result in the fast drug diffusion and incomplete embolization, inducing systemic toxicity and impairing the efficacy of TACE therapy. Therefore, it is of great importance to construct alternative formulations based on commercial Lipiodol to achieve the improved efficacy and safety of HCC treatment.

Department of Experimental and Clinical Biomedical Sciences, University of Florence, Florence, Italy.
Cancer cachexia is a multifactorial syndrome characterized by a progressive loss of body weight occurring in about 80% of cancer patients, frequently representing the leading cause of death. Dietary intervention is emerging as a promising therapeutic strategy to counteract cancer-induced wasting. Serine is the second most-consumed amino acid (AA) by cancer cells and has emerged to be strictly necessary to preserve skeletal muscle structure and functionality.
