Identification and validation of microglia-associated genes in ischemic stroke using single-cell and bulk RNA-seq. (PubMed, Mol Brain) - "Interestingly, Tlr2 and Adapalene exhibited a strong binding affinity (- 9.73 kcal/mol). qRT-PCR analysis revealed significantly elevated mRNA expression levels of Cd14, Csf1, and Tlr2 in tMCAO mice compared to sham-operated controls (p < 0.01). This study identified and validated 3 key genes (Cd14, Csf1, and Tlr2) associated with IS, which may serve as novel targets for IS diagnosis and treatment strategies."

Identification of potent high-affinity secondary nucleation inhibitors of Aβ42 aggregation from an ultra-large chemical library using deep docking. (PubMed, Mol Syst Biol) - "The two most potent compounds showed potency better than adapalene, a previously reported potent inhibitor of Aβ aggregation. Consistent with the intended mechanism of action, these two compounds also proved to be high-affinity binders of Aβ fibrils with an equilibrium dissociation constant in the low nanomolar range in surface plasmon resonance experiments. These results provide evidence that structure-based docking methods based on deep learning represent a cost-effective and rapid strategy to identify potent hits for drug development targeting protein misfolding diseases."

The Dark Side of Oral Antibiotics: Adverse Events of Consideration in Dermatology. (PubMed, J Drugs Dermatol) - "To mitigate these risks, dermatologists should prioritize narrow-spectrum antibiotics and incorporate combination topical therapies containing benzoyl peroxide (BPO), such as the triple-combination of clindamycin, adapalene, and BPO, to help curb antibiotic resistance. Prudent antibiotic use, combined with topical regimens utilizing BPO, optimizes treatment outcomes while minimizing systemic adverse effects and resistance. Ongoing education and research are essential to refine prescribing practices that balance therapeutic benefits with long-term patient and public health."

13-cis-retinoic acid modulates porcine ovarian granulosa cell differentiation via retinoic acid signaling-FoxA1 axis: Implications for ovarian follicular development and luteinization. (PubMed, Theriogenology) - "13cRA promoted RARβ/RXRβ receptor heterodimer formation, with pharmacological activation (Adapalene) potentiating LHR and PGR expression and receptor knockdown diminishing their expression...13cRA-mediated FoxA1 expression suppression occurred through CRABP2-dependent nuclear shuttling and RARβ/RXRβ receptor heterodimer activating, with combinatorial modulation of CRABP1/CYP26 system components (CYP26A1 and CYP26B1) significantly altering FoxA1 regulatory dynamics. Finally, we conclude that 13cRA can inhibit FoxA1 expression through RA signaling molecules (CRABP2, RARβ/RXRβ heterodimer, CRABP1, CYP26A1 and CYP26B1) and thus promote the differentiation of porcine ovarian granulosa cells."
