    [VIRTUAL] Hyperandrogenic effects on female fertility and pregnancy outcome () -  Nov 5, 2020 - Abstract #ISGEI2020ISGE-I_492;    
    Widely used stimulation protocols for patients with hyperandrogenism and PCOS are Letrozole, Сlomiphene, as well as mini stimulation with recombinant gonadotropins...In patients with PCOS, in 70% of cases, non-receptive endometrium was detected, with premature maturation in most cases. The correct assessment of patients before the IVF treatment, as well as the preliminary preparation and normalization of hormonal levels and metabolism, positively affect the amount of mature oocytes, therefore the amount of euploid embryos and the maturity of the endometrium, significantly increase the chance of pregnancy in IVF cycles.

    [VIRTUAL] Changes in T cell clonality in AWARE-1 study, a window-of-opportunity study with atezolizumab and the oncolytic virus pelareorep in early breast cancer (virtual poster hall) -  Nov 3, 2020 - Abstract #SITC2020SITC_2109;    
    P1
    Background A previous phase 2 study in metastatic breast cancer demonstrated a statistically significant improvement in overall survival (OS) in patients treated with pelareorep (pela) in combination with paclitaxel (PTX) versus PTX alone.1 Given that pela is an intravenously delivered immuno-oncolytic reovirus, we hypothesized that the OS benefit from pela + PTX may be attributed to an adaptive T cell response triggered by pela...Five cohorts will be examined: Cohort 1: HR+/HER2-neg (10 patients) receiving pelareorep + letrozole; Cohort 2: HR+/HER2-neg (10 patients) receiving pelareorep + letrozole + atezolizumab; Cohort 3: TNBC (6 patients) receiving pelareorep + atezolizumab; Cohort 4: HER2+/HR+ (6 patients) receiving pelareorep + trastuzumab + atezolizumab; Cohort 5: HER2+/HR- (6 patients) receiving pelareorep + trastuzumab + atezolizumab...In general, most of the tissue-expanded T cell clones were also seen in the peripheral blood. Conclusions Overall, these preliminary data from cohort 1 of AWARE-1 demonstrate that pela mediates priming of a T cell-based immune response that occurs both systemically and within breast cancer tissue.

    Preclinical, Journal:  Use of Bao Gui capsule in treatment of a polycystic ovary syndrome rat model. (Pubmed Central) -  Oct 24, 2020   
    Letrozole was used to induce a PCOS model in rats, which were then randomly divided into four groups (n=9): Control, Model, high‑dose BGC (BGC‑H) and low‑dose BGC (BGC‑L) group...BGC also effectively reduced the level of IL‑6 and TNF‑α, and the expression of IKKβ, NF‑κB and SOCS3 in the hypothalamus of PCOS model rats. These results suggest that BGC may effectively improve hyperandrogenism, insulin resistance, endometrial receptivity and the low‑grade chronic inflammation in the hypothalamus.

    Journal:  Effect of electroacupuncture on levels of serum sex hormones and expression of ovarian auto-phagy related factors in rats with polycystic ovary syndrome (Pubmed Central) -  Oct 10, 2020   
    Taking together, these results demonstrated that decreased GPR30 induces actin depolymerization through SRC-1 and PI3K/mTORC2 pathways and ultimately impairs learning and memory, indicating its potential role as a therapeutic target against hippocampus-based, E2-related memory impairments. EA intervention can reduce serum T, LH and AMH contents, and the ratio of ovarian LC3 Ⅱ/Ⅰ and up-regulate ovarian PI3K and AKT in PCOS rats, which may contribute to its effect in improving anovulatory infertility by suppressing autophagy.
