Multiplex cytokine profiling of stimulated splenocytes from the letrozole-induced PCOS mouse model (Exhibit Hall F1; Poster Board Number: B932) - Apr 20, 2024 - Abstract #IMMUNOLOGY2024IMMUNOLOGY_2512; Altogether, the decrease in pro-inflammatory cytokines may be linked to the likelihood of increased testosterone levels, as presented in previous studies on LET-treated female mice. Testosterone has immunomodulatory properties, but the biological process involved needs further investigation to determine the efficiency of using murine models to study inflammation in PCOS.

Preclinical, Journal: Gene Expression in Porcine Bulbourethral Glands. (Pubmed Central) - Apr 13, 2024 Gene expression for these two key proteins in androgen signaling was quite low during the initial allometric growth in the late juvenile and prepuberal intervals, suggesting that this initial growth was not primarily stimulated by androgens. These observations are consistent with a more direct estrogen-mediated inhibition of growth via GPER previously proposed, with the sensitivity extending into the late juvenile interval when estrogens as well as androgens are normally relatively low.

Journal, Metastases: Recurrent severe hypocalcemia following chemotherapy regimen changes in advanced breast cancer: two case reports. (Pubmed Central) - Mar 29, 2024 It is possible that antitumor drugs affect calcium and bone metabolism associated with bone metastases. While these cases are rare, it is crucial for oncologists to be aware of hypocalcemia not only at the initiation of bone-modifying agents but also throughout the entire antitumor therapy, as hypocalcemia can lead to fatal outcomes.

Preclinical, Journal: Neonatal aromatase inhibition blocked defeminization of AVPV Kiss1 neurons and LH surge-generating system in male rats. (Pubmed Central) - Mar 27, 2024 The results of the present study showed that the neonatal administration of letrozole (LET), a nonsteroidal aromatase inhibitor, within 2?hours of birth rescued AVPV Kiss1 expression and the LH surge in adult male rats, while the neonatal administration of testosterone propionate (TP) irreversibly attenuated AVPV Kiss1 expression and the LH surge in adult female rats...Moreover, neonatal TP administration significantly decreased the number of arcuate (ARC) Kiss1-expressing and Kiss1-Cre-activated tdTomato-positive cells and suppressed LH pulses in adult gonadectomized female rats; however, neonatal LET administration failed to affect them. These results suggest that E2 converted from neonatal testosterone is primarily responsible for the defeminization of AVPV kisspeptin neurons and the subsequent GnRH/LH surge generation in male rats.

- |||||||||| Comparison of Response with Chemotherapy vs Endocrine Therapy and its Association with Ki67 in Hormone Receptor Positive Metastatic Breast Cancer (Exhibition area) - Mar 19, 2024 - Abstract #ESMOBC2024ESMO_BC_477;
Patients eligible for the study were offered hormone therapy (Tamoxifen 20mg daily in premenopausal and letrozole 2.5mg daily for post-menopausal women) or chemotherapy (single agent doxorubicin 60mg/m2 every 3 weeks for 4 cycles or single agent paclitaxel 175mg/m2 every 3 weeks for 4 cycles) after randomization into both groups. Ki67 scores can help stratify the patients to identify those who will gain the most benefit from either treatment approach as shown in our study where high Ki67 scores are correlated with significantly better responses with chemotherapy and hormonal therapy offered better responses in low Ki67 subset.
