Targeted sulfur(VI) fluoride exchange-mediated covalent modification of a tyrosine residue in the catalytic pocket of tyrosyl-DNA phosphodiesterase 1.

Developing effective inhibitors of the DNA repair enzyme tyrosyl-DNA phosphodiesterase 1 (TDP1) has been challenging because of the enzyme shallow catalytic pocket and non-specific substrate binding interactions. Recently, we discovered a quinolone-binding hot spot in TDP1's active site proximal to the evolutionary conserved Y204 and F259 residues that position DNA. Sulfur (VI) fluoride exchange (SuFEx) is a biocompatible click chemistry reaction that enables acylation of protein residues, including tyrosine.

Asymmetric Engagement of Dimeric CRL3 by the Molecular Glue UM171 Licenses Degradation of HDAC1/2 Complexes.

UM171 is a potent small molecule agonist of ex vivo human hematopoietic stem cell (HSC) self-renewal, a process that is tightly controlled by epigenetic regulation. By co-opting KBTBD4, a substrate receptor of the CULLIN3-RING E3 ubiquitin ligase complex, UM171 promotes the degradation of members of the CoREST transcriptional corepressor complex, thereby limiting HSC attrition. However, the direct target and mechanism of action of UM171 remain unclear.

Adherence to the Mediterranean diet in two Moroccan populations living at different distances from the Mediterranean Sea.

Background: There is growing strong scientific evidence over the past few decades that the Mediterranean diet (MD) has protective effects on cardiometabolic health.

Objective: This study aimed to assess MD adherence and its association with sociodemographic and lifestyle factors among women living in two Moroccan provinces, El Jadida and Tetouan, located at different distances from the Mediterranean Sea.

Material And Methods: It is a cross-sectional study involved 355 subjects of which 55.

Dietary behavior of pregnant women in the province of El Jadida and impact of low birth weight on the anthropometric status of newborns. Case-control study.

Background: Low birth weight (LBW) is a major health problem responsible for neonatal mortality and morbidity such as diabetes, obesity and cardiovascular disease in adulthood.

Objective: This case-control study aims to compare data on the intake of energy, macro and micronutrient in two groups of pregnant women, who gave birth to low birth weight (LBW) babies named cases and those who gave birth to babies of normal weight (NW) called controls.

Material And Methods: The collection of information was done using an established questionnaire for 400 pregnant women, allowing the collection of data on socio-demographic and obstetrical factors.

Meal intake in an adult Moroccan population: determinants and implications for weight status.

Background: In recent decades, the Moroccan population has changed its dietary practices, particularly those related to meal-taking. It is about irregular meal schedules, reduced frequency and shorter time of meal taking times, as well as a decrease in family meal-taking. All these factors are likely to influence its nutritional status.
