Background: About half of the patients suffering from Alzheimer's disease (AD) display sleeping disorders. Disruptions in the central circadian clock (CC), located in the brain, accelerate AD pathogenesis, making the CC a promising target. In preclinical trials, this strategy have shown efficacy but clinical results are inconsistent.

Antiproliferative and Morphological Effects of Fenretinide Lipid Nanosystems in Colon Adenocarcinoma Cells.

Colon adenocarcinoma is characterized by the downregulation of the retinoic acid receptor, making natural retinoids such as all-trans retinoic acid, 9-cis retinoic acid and 13-cis retinoic acid effective in treatment and chemoprevention due to their ability to increase RARβ expression. However, major limitations to their use include tolerability and acquired resistance. In this study, we evaluated fenretinide, a semisynthetic derivative of all-trans retinoic acid, in an HT-29 cell line.

"I Didn't Have to Worry about It": Patient and Family Experiences with Health System Involvement in Notifying Relatives of Genetic Test Results.

Introduction: In the USA, patients who undergo genetic testing for hereditary cancer risk are responsible for informing relatives about their genetic test results, but many relatives never find out they might be at risk. A health system-mediated relative notification program might help fill this gap, but questions remain about the acceptability of this approach.

Methods: We analyzed qualitative data from a single-arm, nonrandomized, mixed-methods study to understand how patients and families experienced a new health system-mediated relative notification program.

Chalcones induce apoptosis, autophagy and reduce spreading in osteosarcoma 3D models.

Osteosarcoma is the most common primary bone malignancy with a challenging prognosis marked by a high rate of metastasis. The limited success of current treatments may be partially attributed to an incomplete understanding of osteosarcoma pathophysiology and to the absence of reliable in vitro models to select the best molecules for in vivo studies. Among the natural compounds relevant for osteosarcoma treatment, Licochalcone A (Lic-A) and chalcone derivatives are particularly interesting.

Nano-fenretinide demonstrates remarkable activity in acute promyeloid leukemia cells.

Acute promyelocytic leukemia (APL) is characterized by rearrangements of the retinoic acid receptor, RARα, which makes all-trans retinoic acid (ATRA) highly effective in the treatment of this disease, inducing promyelocytes differentiation. Current therapy, based on ATRA in combination with arsenic trioxide, with or without chemotherapy, provides high rates of event-free survival and overall survival. However, a decline in the drug activity, due to increased ATRA metabolism and RARα mutations, is often observed over long-term treatments.
