In Vitro Cell-Based MTT and Crystal Violet Assays for Drug Toxicity Screening.

The development of novel drug candidates is a current challenge in pharmacology where therapeutic benefits must exceed side effects. Toxicology testing is therefore a fundamental step in drug discovery research. Herein, we describe the first line of toxicology testing program, consisting in cell-based high-throughput screening assays, which have the advantage of being easy, rapid, cheap, and reproducible while providing quantitative information.

Vitamin Nutritional Status in Patients with Pancreatic Cancer: A Narrative Review.

Due to the high mortality rate in Western countries, pancreatic cancer is considered one of the , leaving patients and their families with little hope upon diagnosis. Although surgical and drug therapies are critical for cancer patients to improve life expectancy and alleviation of suffering, nutrition plays a key role in improving cancer treatment outcomes. This narrative review, conducted as part of the activities of the Italian Society of Human Nutrition (SINU) working group in oncology, focuses on the prevalence of vitamin malnutrition among pancreatic cancer patients.

In Vivo Identification of H3K9me2/H3K79me3 as an Epigenetic Barrier to Carcinogenesis.

The highly dynamic nature of chromatin's structure, due to the epigenetic alterations of histones and DNA, controls cellular plasticity and allows the rewiring of the epigenetic landscape required for either cell differentiation or cell (re)programming. To dissect the epigenetic switch enabling the programming of a cancer cell, we carried out wide genome analysis of Histone 3 (H3) modifications during osteogenic differentiation of SH-SY5Y neuroblastoma cells. The most significant modifications concerned H3K27me2/3, H3K9me2, H3K79me1/2, and H3K4me1 that specify the process of healthy adult stem cell differentiation.

Exploring the 1,3-benzoxazine chemotype for cannabinoid receptor 2 as a promising anti-cancer therapeutic.

The discovery of selective agonists of cannabinoid receptor 2 (CB) is strongly pursued to successfully tuning endocannabinoid signaling for therapeutic purposes. However, the design of selective CB agonists is still challenging because of the high homology with the cannabinoid receptor 1 (CB) and for the yet unclear molecular basis of the agonist/antagonist switch. Here, the 1,3-benzoxazine scaffold is presented as a versatile chemotype for the design of CB agonists from which 25 derivatives were synthesized.

DNA-Protein-Interaction (DPI)-ELISA Assay for PPAR-γ Receptor Binding.

Dysregulation of peroxisome proliferator-activated receptor (PPAR)-γ has been described in a plethora of pathological conditions, such as diabetes, obesity, inflammatory-related diseases, and cancer. Therefore, identifying novel drugs that are able to restore PPAR-γ activity is a current challenge, which is however slowed down by the lack of a rapid and reproducible activity assay. To date, only a few methods are able to characterize PPAR-γ activity and most of them are expensive, time-consuming, and not always quantitative.
