Journal, IO biomarker: Alleviation of adipose-hepatic glycolipid dysregulation by acetate in experimental PCOS model is associated with NF-?B/NLRP3 repression. (Pubmed Central) - Dec 4, 2023 Female Wistar rats (8-week-old) were randomly allocated into four groups of n?=6/group, which received vehicle, sodium acetate (200?mg), letrozole (1?mg/kg), and letrozole plus sodium acetate, respectively...Nonetheless, concomitant acetate supplementation attenuated these derangements. The present data collectively suggest that acetate ameliorates adipose-hepatic glycolipid dysregulation in experimental PCOS model by attenuating androgen excess and NF-?B/NLRP3 immunoreactivity.

Journal, Next-generation sequencing, MSi-H Biomarker: Outcomes of fertility preservation treatments in patients with endometrial cancer with different molecular classifications based on an NGS panel. (Pubmed Central) - Nov 30, 2023 The combination of gonadotropin-releasing hormone analogues (GnRH-a) and letrozole (HR: 3.43; 95% CI: 1.81-6.52; P< 0.001) was associated with a significantly higher cumulative CR rate...In wild-type TP53 patients, PTEN and PIK3CA mutations significantly prolonged the duration of treatment to achieve CR (log rank P=0.034; P=0.018). The implementation of molecular classification for EC patients undergoing fertility-sparing treatment is promising and can facilitate the selection of appropriate medical regimes to achieve better outcomes in patients with EC who require fertility preservation treatment.

A novel ROR1 inhibitor CPD86 suppresses Triple-Negative Breast Cancer cells via regulation of AKT/GSK3? pathway (Hall 2-3) - Nov 4, 2023 - Abstract #SABCS2023SABCS_1989; CPD86 also represses TNBC cell migration and invasion while leaving non-malignant cells unharmed. This study highlights that ROR1 inhibitors could be developed as a potential therapeutic for TNBC and the data would serve as proof-of-concept justification for evaluation in other ROR1-upregulated cancers.

Narazaciclib's differential targets and kinase inhibitory activity contribute to the enhanced inhibition of tumor growth in preclinical models (Hall 2-3) - Nov 4, 2023 - Abstract #SABCS2023SABCS_1949; P1, P1/2 Narazaciclib is in Ph I trials; NCT04739293 and CXHL1900340; studying different administration regimens and in endometrial cancer in combination with letrozole (NCT05705505)...Kd values of CDK4/cyclinD1 binding show similar trends; abemaciclib (0.08 nM), narazaciclib (0.18 nM), palbociclib (0.75 nM) and ribociclib (1.3 nM)...Our findings identify important differences generated from assay models studying kinase inhibition, binding and pathway engagement. Understanding the role of the differential targets engaged by narazaciclib, the potential enhanced antitumor immunity and the sensitization by autophagy inhibitors to cell death, will guide future clinical studies.

Locoregional management of the primary tumor should be discussed in the context of a multidisciplinary team approach and should be individualized based on the individual patient's need.
