UTSA study describes drug that could prevent infertility in cancer patients

(University of Texas at San Antonio) A new study led by Brian Hermann, assistant professor of biology at The University of Texas at San Antonio (UTSA), shows promising evidence that a medication previously used to prevent infections in cancer patients can also keep them from becoming infertile. Losing fertility is a frequent problem among cancer patients, as treatments for the disease often halt sperm production.

Abstract Mechanistic target of rapamycin (mTOR) controls cell growth and metabolism in response to environmental and metabolic signals. Rapamycin robustly extends the lifespan in mammals and has clinical relevance in organ transplantation and cancer therapy but side effects include male infertility. Here, we report that chronic rapamycin treatment causes spermatogenic arrest in adult male mice due to defects in sex body formation and meiotic sex chromosome inactivation (MSCI). Many sex chromosome-linked genes were up-regulated in isolated pachytene spermatocytes from rapamycin-treated mice. RNA-Seq analysis also i...

Increasingly patients are seeking the advice of reproductive medicine clinicians and scientists to enable them to preserve their gametes and/or embryos. The reasons are either as a form of reproductive insurance, or more important, to preserve their fertility before undergoing gonadotoxic therapy, most commonly chemotherapy. It is a guideline of the American Society of Clinical Oncology that all health care providers caring for adult and pediatric patients with cancer should address the possibility of infertility as early as possible before treatment starts (1).

Abstract Neutrophil extracellular traps (NET), extruded decondensated chromatin entangled with neutrophil proteases, have been first identified in neutrophils stimulated with bacteria or phorbol myristate acetate (PMA) via activation of NADPH oxidase and the generation of reactive oxygen species. Although the first findings demonstrated the beneficial role of NET formation by trapping the bacteria and limiting their dissemination, numerous studies in the recent decade revealed the multifunctional aspects of NET formation which manifests itself not only in the context of anti-microbial effect but also as a patholog...

CONCLUSIONS: Our results demonstrate that chronic exposure to ECs causes major physiological changes in the liver, likely to affect multiple systems in the body and which may predispose individuals to increased disease risks. PMID: 30641261 [PubMed - as supplied by publisher]

AbstractSome studies have suggested that infertility is a risk factor for endometrial, ovarian and breast cancer. The study aimed to create a comprehensive picture of the association between infertility and the risk of ovarian, endometrial and breast cancer, and whether any association could be explained by ovulatory disturbances, endometriosis or nulliparity. In a population-based cohort of 2,882,847 women, cox regression analysis was used to investigate cancer incidence among infertile women. Overall, infertility was associated with a higher incidence rate of ovarian (adjusted hazard ratio [aHR] 1.53, 95% confidence inte...

CONCLUSION: Higher-quality research is needed to clarify DMPA's side effects and benefits. In absence of such evidence, patient-centered counseling should incorporate the available evidence while acknowledging its limitations and recognizing the value of women's lived experiences.

Abstract Over the past two decades, public health has focused on the identification of environmental chemical factors that are able to adversely affect hormonal function, known as endocrine disruptors (EDs). EDs mimic naturally occurring hormones like estrogens and androgens which can in turn interfere with the endocrine system. As a consequence, EDs affect human reproduction as well as post and pre-natal development. In fact, infants can be affected already at prenatal level due to maternal exposure to EDs. In particular, great attention has been given to those chemicals, or their metabolites, that have estrogeni...

On an afternoon in November, a couple hosted a birthday party for their 1-year-old son. As family and friends gathered around the child to sing “Happy Birthday,” his parents addressed a milestone that reached well beyond the room. “It was emotional,” recalls the mother. “It took a lot more than a nine-month pregnancy to get him, and we wouldn’t be where we are without everyone’s support.” Many parents will tell you their child is miraculous. But the mere existence of this particular boy, who just a month earlier had taken his first steps, brings the miracle somehow closer to ...
