A new report from Mayo Clinic in Rochester, Minnesota presents fresh data on the efficacy of anti-obesity medications (AOM) among breast cancer survivors taking aromatase inhibitors (AI). Aromatase inhibitors are used as long-term adjuvant treatment for breast cancer in postmenopausal women, but can be associated with weight gain and increased cardiometabolic risk. The study found that breast cancer survivors taking AI had a lower total body weight loss percentage compared to patients without a history of breast cancer or AI use. Further studies are needed to understand the mechanisms behind this differential weight loss response. [Extracted from the article]

Researchers from Johns Hopkins University School of Medicine have conducted a cohort study to evaluate genetic predictors of musculoskeletal symptoms associated with aromatase inhibitors (AIMSS). AIMSS are common and often lead to discontinuation of AI treatment. The study aimed to validate the association between 10 SNPs and AI discontinuation due to AIMSS. The results showed that although more Black and Asian women developed AIMSS compared to White women, the AI discontinuation rates were similar across racial groups. None of the SNPs were significantly associated with AIMSS or AI discontinuation. Future analyses will explore additional genetic markers and patient-reported outcome predictors of AIMSS, as well as differences by race. [Extracted from the article]

A recent study conducted at Sun Yat-sen University in Guangzhou, China, explored the effectiveness and safety of different dosage forms of gonadotropin-releasing hormone (GnRH) agonist in premenopausal hormone receptor-positive breast cancer patients. The study included 1109 patients who were treated with GnRH agonist plus selective estrogen receptor modulator or aromatase inhibitor. The results showed that both the 1-month and 3-month GnRH agonist regimens achieved more than 90% estradiol (E2) inhibition within 24 months, confirming the noninferiority of the 3-month regimen. The study concluded that the ovarian function suppression with the 3-month GnRH agonist was not inferior to that with the 1-month regimen, regardless of age or combination with other medications.

A preprint abstract from biorxiv.org discusses the role of aromatase in maintaining bone mass in male mice. Aromatase is an enzyme that converts testosterone into estradiol, and its inhibition has been shown to cause bone loss in men and post-menopausal women. The study focused on adipose tissue-specific aromatase knockout mice and found that these mice exhibited lower bone mineral density, insufficient calcification of bone, and decreased levels of phosphate reabsorption in the kidney. The results suggest that locally biosynthesized estrogens by aromatase in adipocytes play a significant role in maintaining bone mass through the regulation of phosphate reabsorption. However, it is important to note that this preprint has not been peer-reviewed. [Extracted from the article]

A study conducted in Buenos Aires, Argentina, examined the expression of estrogen-related receptor gamma (ERR gamma) and aromatase mRNA in the placental tissues of large for gestational age (LGA) newborns. The researchers found that ERR gamma 1 mRNA was significantly higher in LGA newborns compared to those of adequate for gestational age (AGA). Additionally, the total aromatase mRNA and protein levels were lower in LGA newborns, while the active aromatase/total aromatase ratio was higher. These findings suggest that dysregulation of ERR gamma 1 in the placenta may disrupt the estrogen-androgen balance in the intrauterine environment, potentially impacting fetal programming in LGA newborns.

A recent study conducted by researchers at Yonsei University College of Medicine in Seoul, South Korea, explored the relationship between body composition and treatment outcomes in patients with hormone receptor-positive, HER2-negative advanced breast cancer. The study found that low skeletal muscle radiodensity (SMD), a measure of myosteatosis, was associated with worse progression-free survival (PFS) in patients receiving CDK4/6 inhibitors and aromatase inhibitors as first-line therapy. This association was particularly strong in pre-menopausal patients and those without visceral metastases. The findings suggest that computed tomography (CT)-derived myosteatosis could be a useful predictor of therapeutic response in this patient population. [Extracted from the article]

A study conducted by researchers at Mahidol University in Bangkok, Thailand, explored the influence of various hormones on the success of in vitro fertilization (IVF) treatments. The study compared levels of insulin-like growth factor 1 (IGF-1), progesterone (P4), androstenedione, aromatase, and estrogen (E2) in follicular fluid (FF) between subjects with successful and unsuccessful outcomes. The researchers found that unsuccessful pregnancies had lower levels of androstenedione but higher levels of aromatase and IGF-1 in both FF and serum, suggesting a decreased substrate availability for estrogen production in subjects with poor ovarian response. The study also found that IGF-1, P4, androstenedione, and E2 were likely synthesized primarily in FF rather than serum. This research provides insights into the hormonal factors that may impact the success of IVF treatments. [Extracted from the article]

Additionally, the study discovered a new case of brain-functional lateralization, where the right hemisphere showed increased aromatase activity in certain areas. This lateralization may contribute to the left-hemisphere dominant processing and perception of pup calls to release parental behavior. It is important to note that this preprint has not been peer-reviewed. [Extracted from the article]

A study conducted at Afe Babalola University investigated the effects of two anticonvulsant drugs, diazepam and phenytoin, on ovarian gene transcriptional responses in female rats. The study found that diazepam down-regulated the expression of FSH-R and aromatase genes, inhibiting follicular growth and reducing estrogen levels. On the other hand, phenytoin up-regulated the expression of FSH-R and aromatase genes, promoting follicular growth and increasing estrogen levels. Both drugs were found to affect the production of reactive oxygen species and oxidative stress. This research provides insights into the potential effects of these anticonvulsant drugs on female reproductive health. [Extracted from the article]

A study conducted by researchers at the University of Pittsburgh Medical Center examined the effectiveness of treatment options for older patients with HR+/HER2- metastatic breast cancer.
