Premature Ovarian Failure and Ovarian Autoimmunity - 0 views

  •  
    Premature ovarian failure shown to be autoimmune.  This study from '97 describes the mechanism of the autoimmune ovarian failure.  Now, case studies are emerging of young women developing premature ovarian failure following the HPV vaccine.

Oncotarget | Preclinical evaluation of a nanoformulated antihelminthic, niclosamide, in... - 0 views

  • Ovarian cancer is the most lethal gynecologic malignancy in the world
  • paclitaxel represents a breakthrough in the treatment of ovarian cancer, the overall 5-year survival rate of patients with stage III disease is still approximately 40%
  • Targeting cancer stem cells is an emerging concept in cancer therapy
  • ...8 more annotations...
  • Ovarian cancer stem cells play an important role in chemoresistance and cancer recurrence
  • Furthermore, recent studies indicate that niclosamide exhibits anticancer effects against various human cancer cells by acting on multiple cell signaling pathways and inducing mitochondrial uncoupling [16–21]
  • has low systemic bioavailability (~10%) when administered orally, which is beneficial for treating local parasitic infections of the intestines while minimizing systemic exposure
  • The nano-NI demonstrated significantly higher inhibitory effects on sphere formation than the original niclosamide did
  • the nano-NI formulation decreased the metabolic activity of ovarian cancer cells and caused a metabolic shift from oxidative phosphorylation to glycolysis
  • This toxicity evaluation showed that oral nano-NI had no toxic effect on either group of mice in terms of weight, plasma albumin levels, and blood cell counts, and revealed no adverse effects on vital organ function in the rodents, which suggests that nano-NI is safe for animals
  • niclosamide inhibits tumor cell growth by interrupting multiple pathways (Wnt, Notch, STAT3, NF-κB, and mTORc1) and the generation of reactive oxygen species in several cancer cells
  • The current standard therapy for ovarian cancer includes taxanes and platinum-based chemotherapy after cytoreductive surgery. Among treated patients, nearly 70 to 80% will experience disease recurrence
  •  
    nano-Niclosamide more effective than traditional Niclosamide in in vitro and in vivo ovarian cancer.

The use of antioxidants with first-line chemotherapy in two cases of ovarian cancer - 0 views

  •  
    IV, high dose, vitamin C adjunct therapy shown to aid in the remission in to women with ovarian cancer. These two cases studies do only looked and high dose antioxidant therapy as an adjunct in ovarian cancer and they found good results.

Ovarian failure and flares of systemic lupus... [Arthritis Rheum. 1999] - PubMed - NCBI - 0 views

  •  
    Low estrogen levels in ovarian failure patients found to reduce flares in those with Lupus.  Estrogen can promote inflammation, especially high estrone levels.  It is easy to see how ovarian failure and a drop in estrogen could reduce inflammation and thus autoimmune flares.

Journal of Ovarian Research | Full text | Evaluation of the ovarian reserve function in... - 0 views

  •  
    Study finds decreased ovarian reserve in women 20-29 with metabolic syndrome compared to controls.  They determined this via ovarian volume measurements as FSH, LH, Estradiol, and Progesterone did not differ.   One item of interest was that women with MetS, had significantly higher Testosterone levels compared to controls.  This association of MetS and elevated Testosterone in women has been shown consistently in the literature.  This should bring great questions to the doping of Testosterone in women today.

EHP - Bisphenol A Exposure during Adulthood Causes Augmentation of Follicular... - 0 views

  •  
    Bisphenol A shown to disrupt ovarian estrogen production from exposure in adults.  The point of this that is important is that BPA, a xenoestrogen, can infact disrupt physiologic hormone production in adults, and contribute to ovarian failure.  BPA, itself, is 1,000 fold weaker than E2, yet it disrupts ovarian function.

  •  
    Studies in breast cancer and prostate cancer have revealed different effects by ER alpha vs ER beta.  It is no surprise that the same effects are found in ovarian cancer.  This study found ER alpha antagonists and ER beta agonists "significantly" suppressed growth in the ovarian cancer cell lines SKOV3 and OV2008.  Also, ER alpha agonist and ER beta antagonist "significantly" increased growth in the same cell lines.  These findings point to in increased proliferation with ER alpha and decreased with ER beta.  This is consistent with breast and prostate cancer also.

Growth Inhibition of Ovarian Tumor-Initiating Cells by Niclosamide | Molecular Cancer T... - 0 views

  • Ovarian cancer is the most lethal gynecologic malignancy and the fifth-most cause of overall cancer death of women in developed countries
  • An increasingly accepted cancer stem cell hypothesis regards tumors as caricatures of normal organs, possessing a hierarchy of cell types, at various stages of aberrant differentiation, descended from precursor tumor-initiating cells (TIC) cells that are highly resistant to conventional cytotoxics
  • Significant changes of gene expression in 2,928 genes were identified after niclosamide treatment for different time periods
  • ...14 more annotations...
  • uncoupling of mitochondrial oxidative phosphorylation is believed to be its anti-helminthic mechanism of action
  • we hypothesized that niclosamides antagonistic effects on OTICs could, in part, be due to its disruption of metabolism
  • niclosamide represses metabolic enzymes responsible for bioenergetics, biosynthesis, and redox regulation specifically in OTICs, presumably leading to mitochondrial intrinsic apoptosis pathways, loss of tumor stemness, and growth inhibition
  • niclosamide treatment resulted in a more than 20% increase in reactive oxygen species (ROS) in cultured OTICs
  • niclosamide, which has proved to be safe and effective for the past 2 decades against numerous parasites, inhibited OTIC growth both in vitro and in vivo
  • Our results showed that genes participating in protein complexes of oxidative phosphorylation were downregulated
  • Niclosamide is believed to inhibit mitochondrial oxidative phosphorylation
  • Niclosamide was reported to inactivate NF-κB, causing mitochondrial damage and the generation of ROS, leading to apoptosis of leukemic stem cells
  • niclosamide were identified in a screen for mTOR-signaling inhibitors
  • mTOR was reported to maintain stemness properties of HSCs by inhibiting mitochondrial biogenesis and ROS levels (39), implying that mTOR inhibitors (such as niclosamide) may interfere with mitochondria and various metabolic pathways in TICs via disruption of antioxidant responses
  • We observed Wnt hyperactivity in OTICs, in agreement with previous hypotheses of Wnt inhibitor effectiveness as an ovarian cancer therapy
  • niclosamide has now been independently identified in screens for Wnt inhibitors
  • downregulation of the Wnt/β-catenin target oncogenes survivin and c-Myc
  • ovarian carcinogenesis, the cell-to-cell signaling pathway Notch (8), were also suppressed by niclosamide (data not shown). These results agree with another recent niclosamide study in leukemia (49), and it has been widely hypothesized that disruption of Notch signaling may represent a highly effective therapy for ovarian and other solid tumors, via its essentiality to maintaining TIC stemness
  •  
    Niclosamide, common anti-parasitic medication, inhibits cellular metabolism and increases ROS; both of which provide powerful anti-proliferative, anti-cancer treatment mechanism in TICs. Powerful target therapy for cancer stem cells. Also shown to inhibit Wnt stimulated oncogenes survivin and c-Myc, disrupts Notch signaling, inactivates NF-kappaBeta, and inhibits mTOR-signaling.  This has been found in in vitro and in vivo studies.
