Study: Glyphosate damages reproductive development in rats, increasing risk for cancer and infertility

(NaturalNews) Glyphosate -- the active ingredient of Monsanto's blockbuster herbicide Roundup -- may disrupt development of the uterus, leading to fertility problems and cancer, according to a study conducted by researchers from Argentina and published in the journal Toxicology.Roundup...

Authors: Guo J, Cao B, Xu X, Wu F, Zhu B Abstract Endometriosis is a common gynecological disease characterized by the outgrowth of the endometrium, however, the detailed molecular etiology remains largely uncharacterized. Recent studies have implicated that endometriosis is potentially a precancerous lesion, and that CCCTC‑binding factor (CTCF) mutations may be involved in the pathogenesis of this disorder. However, the detailed CTCF mutation spectrum in Chinese patients with ovarian endometriosis remains largely unknown. In the present study, a cohort of 92 patients with ovarian endometriosis were analyzed...

CONCLUSIONS: Metabolomics analysis of the eutopic endometrium in endometriosis was effectively characterized by UHPLC-ESI-HRMS-based metabolomics. Our study supports the importance of purine and amino acid metabolites in the pathophysiology of endometriosis and provides potential biomarkers for semi-invasive diagnosis of early-stage endometriosis.

A new study in the journal Nature Cell Biology has uncovered information about a key stage that human embryonic cells must pass through just before an embryo implants. The research, led by UCLA biologist Amander Clark, could help explain certain causes of infertility and spontaneous miscarriage.Infertility affects around 10 percent of the U.S. population, and roughly 15 to 20 percent of all pregnancies in the U.S. end in miscarriage. In many cases, the causes of infertility and miscarriage are unknown.A team led by Clark, a UCLA professor of molecular cell and developmental biology and member of the  Eli and Edythe Br...

Dr. Giuliano Testa, a transplant surgeon at Baylor University Medical Center at Dallas who led the medical team that performed the first successful uterus transplants in the United States, said Tuesday that he hopes “what we are doing is going to shed light on infertility for women.” “I personally never knew it was such a widespread issue,” Testa said at the TIME 100 Gala on Tuesday. “We should be thinking about it not just as a birth, but a wellbeing issue.” Testa attended the TIME 100 Gala after being named by TIME magazine as one of the most influential people in the world for his rol...

We present a case series of 2 sisters in their 20s who presented with isolated uterine leiomyomas and were found to carry a novel mutation for the fumarate hydratase gene. One patient was referred for treatment of infertility and recurrent miscarriages and the other was referred for acute symptomatic anemia due to myomas. Prompt diagnosis of hereditary leiomyomatosis renal cell cancer was made due to a high index of clinical suspicion based on early onset disease and familial clustering as well as characteristic pathologic findings on uterine leiomyoma surgical specimen. Timely diagnosis not only allowed for genetic counse...

This exposure also causes altered gene expression in the female reproductive tract that persists into adulthood. To further explore on a genome-wide basis how neonatal estrogen exposure results in permanent epigenetic changes, we performed RNA-seq and ChIP-seq analyses of DES-treated and contro...

Abstract Forkhead box A2 (FOXA2) is a pioneer transcription factor involved in organ development, function and cancer. In the uterus, FOXA2 is essential for pregnancy and expressed specifically in the glands of the endometrium loss of FOXA2 function occurs during development of endometrial cancer in humans. The present study describes the development of a mouse model for conditional expression of mouse FOXA2. Using a system consisting of a minigene located at the Rosa26 locus, a CAG-S-mFOXA2 allele was generated in embryonic stem cells and subsequently in mice; before activation, the minigene is silent due to a fl...

A second woman in the U.S. born without a uterus has given birth to a baby, thanks to a uterus transplant. The birth took place at Baylor University Medical Center at Dallas, a part of Baylor Scott &White, which performed the first birth via uterus transplant late last year. The baby, born in February, is a girl. The hospital is not revealing the identity of the mother, but says the pregnancy and birth were uncomplicated. The birth is the second in the hospital’s ongoing uterus transplant clinical trial. The women in the trial have absolute uterine factor infertility (AUI), which means their uterus is nonfunction...

AbstractAdult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically. By contrast, radiation is detrimental to both the ovaries and the uterus, thereby causing a gr...

Abstract Endometriosis is a common and challenging condition of reproductive-aged women that carries a high individual and societal cost. The many molecular dissimilarities between endometriosis lesions and eutopic endometrium create difficulties in the development of new drug therapies and treatments. Surgery remains the gold standard for definitive diagnosis, but it must be weighed against the risks of surgical morbidity and potential decreases in ovarian reserve, especially in the case of endometriomas. Safe and effective surgical techniques are discussed within this article for various presentations of endomet...
