RESUMO

INTRODUCTION: Polycystic Ovary Syndrome (PCOS) is an endocrine disorder which accounts for infertility around the world. The disease is characterized by elevated secretion of androgens in the women which results in enlargement of ovaries with accumulation of fluid filled cysts, irregular menstrual cycles, and hirsutism. This study reports the efficacy of a patented, standardized Trigonella foenum-graecum extract (Furocyst®) as an effective phytotherapeutic for effective management of PCOS. OBJECTIVE: This randomized one-arm study assessed the efficacy of Furocyst® in 107 female volunteers over a period of 12 consecutive weeks. METHOD: Following approvals of the Institutional Ethical Committee and clinicaltrials.gov, 107 female volunteers (age: 18-45 years) were recruited. Subjects consumed Furocyst® capsules (1,000 mg/day p.o.) over a period of 12 consecutive weeks. Physical (Sonographic scan, Hirsutism Score, Menstrual cycle, Body Weight, BMI, Height, Waist Circumference and Blood Pressure) and biochemical parameters (LH/FSH ratio, TSH, Prolactin, Fasting insulin, Fasting Glucose, triglyceride, cholesterol, HOMA Index, free and total testosterone, 2-hour GTT, DHEAS) were assessed at the beginning of the study as well as at intervals of 4 weeks till 12 weeks to determine the efficacy of Furocyst® on PCOS induced damage on reproductive and endocrine system. RESULTS: Furocyst® treatment induced >40% reduction of mean cyst sizes in both ovaries with corresponding reduction of in ovarian volumes. LH:FSH ratio was also significantly improved with corresponding reduction in total testosterone and prolactin levels. As a result of improvement in endocrine function, menstrual cycle became regular in the subjects. Furocyst® also reduced the severity of other associated ailments such as insulin resistance, dyslipidemia, and improved liver function significantly. CONCLUSIONS: This study reinstated the efficacy of Furocyst® as a safe phytotherapeutic to reverse the effects of PCOS inflicted damage on the female reproductive system without any adverse events.

RESUMO

Endometriosis is a chronic gynecological disease in women of childbearing age, which leads to infertility with risk of endometrial and ovarian cancer. The pathogenesis of endometriosis is poorly understood, and cure/treatment for it is not available, except for symptomatic treatment. The recurrence rate of endometriosis is high. SLP-2 is an inner mitochondrial membrane protein whose participation has been explained in cases of endometrial stromal cell growth, differentiation and migration, but its role in endometriosis is yet to be understood. Previous studies have found altered expression of stomatin-like protein 2 (SLP-2) in the serum of endometriotic patients. Therefore, we have studied the possible role of SLP-2 in the development of endometriosis. We found the ubiquitous and high expression of SLP-2 in the endometriotic tissue of both human endometriosis patients and rat endometriosis model. SLP-2 is seen in the glandular epithelial cells and stromal cells in the eutopic/normal or non-endometriosis group endometrium from human subjects. Finding high expression levels of SLP-2 in endometriotic tissue and ovarian cystic cells derived from endometriosis patients, we explored the possible role of SLP-2 in the cell aggregation, colonization, migration, and invasion in the human endometriotic cells associated with the progression of the endometriosis. Transient silencing of SLP-2 by its siRNA hinders endometriotic cells, aggregation, migration, and invasion into the extracellular matrix, which confirms SLP-2 involvement in endometriotic disease onset and progression. This study unravels the ubiquitous expression of SLP-2 in the human ectopic endometrial tissue and its role in the endometriotic cell migration, colonization, aggregation, and invasion leading to endometriosis progression.

RESUMO

Objective: The aim of this study was to evaluate the predictive value of Immunohistochemical p53 cut-off scores as an adjunct to routine histopathology for better diagnosis of cervical lesions. Materials and Methods: Prospective study carried out for 1 year. After ethical approval and informed consent, a total of 100 cervical tissue samples were analyzed; chronic cervicitis (CC)-15, cervical intraepithelial neoplasia (CIN)-40, and squamous cell carcinoma cervix (SCC)-45 (FIGO 2018 clinical staging). After routine processing of tissue specimen, hematoxylin and eosin (HE) staining was done. Grading of cervical precancerous lesions (CIN) was done as per World Health Organisation criteria as CIN 1,2 or 3. Broder's grading was assigned for every SCC sample. Results: Mean p53 scores of CC, CIN, and SCC cases were 0.0, 1.70, and 4.38, respectively, CIN 1, 2, and 3 were 1.07, 1.63, and 2.22, respectively. SCC was differentiated from CIN3 with p53 ≥4.5 as predictor for SCC, sensitivity and specificity were 57.8% and 88.9%, respectively. Overall diagnostic accuracy of the proposed scoring system for differentiating CC, CIN, and SCC was 61%, while the accuracy of previous methods of interpreting p53 immunoreactivity as immunoscore >2 or arbitrary cut-off of >10% cells with nuclear positivity was only 48%. Conclusion: ROC-derived immunoscore cut-offs can provide the much-needed objectivity and optimal decision thresholds to immunohistochemistry interpretation.

RESUMO

Transforming growth factor (TGFß) is known to play a major role in establishment and maintenance of endometriosis as reported by our group earlier, the underlying mechanism remains to be explored. We deciphered the involvement of TAK1 in TGFß1- induced cellular responses and delineated the signaling mechanism in human endometriotic cells. The endometriotic cells showed elevated expression of TGFß1 signaling-effector molecules. TGFß1 exposure to endometriotic cells induced the expression of the downstream target molecules indicating that TGFß1 is implicated in the commencement ofTAK1/NFκB-p65/Smad7 cascade. The silencing of TAK1 in endometriotic cells attenuated the TGFß1 -induced NFκB transcriptional activation and nuclear translocation of NFκB-p65 subunit. The pharmacological inhibition of NFκB by QNZ or knockdown of TAK1 reduced the expression of Smad7 and Cox2. The knockdown of TAK1 in endometriotic cells showed G1 phase cell-cycle arrest and showed low BrdU-incorporation in the presence of TGFß1. The inhibition of TAK1 attenuated the TGFß1 signaling activation indicating that TAK1 is a crucial mediator for TGFß1 action in endometriotic cells. The exposure of endometriotic cells to TAK1 inhibitor, celastrol caused activation of caspase-3 and -9 that led to PARP cleavage and induced apoptosis. Simultaneously, autophagy occurred in celastrol-treated and TAK1-silenced cells as was evidenced by the formation of autophagosome and the increased expression of autophagic markers. Thus, TAK1 activation appears to protect the growth of endometriotic cells by suppressing the cell death process. Overall, our study provided the evidence that of TAK1 significant in the endometriotic cell regulation and mediates a functional cross-talk between TGFß1 and NFκB-p65 that promotes the growth and inflammatory response in endometriotic cells.

RESUMO

OBJECTIVE: The objective of this study is to determine the level of pesticides and their role in cases of recurrent pregnancy loss (RPL). MATERIALS AND METHODS: This was designed as a case-control study. Gas chromatography was used to characterize the pesticide level in 70 cases and 70 controls. Case refers to women with RPL, whereas controls refer to women with full-term delivery. RESULTS: A higher level of pesticide, namely beta-hexachlorocyclohexane, malathion, chlorpyrifos, and fenvalerate was found in the case group as compared to control group (P < 0.05). CONCLUSIONS: The present study suggests that high exposure of pesticide (organochlorine and organophosphates) may increase the risk of RPL in females of the subhumid region of India.

RESUMO

Embryo implantation and decidualization are critical events that occur during early pregnancy. Decidualization is synchronized by the crosstalk of progesterone and the cAMP signaling pathway. Previously, we confirmed the role of TPPP3 during embryo implantation in mice, but the underlying role and mechanism of TPPP3 in decidualization has not yet been understood. The current study was aimed to investigate the role of TPPP3 in decidualization in vivo and in vitro. For in vivo experiments, decidual reaction was artificially induced in the uteri of BALB/c mice. TPPP3 was found to be highly expressed during decidualization, whereas in the uteri receiving TPPP3 siRNA, decidualization was suppressed and the expression of ß-catenin and decidual marker prolactin was reduced. In human endometrium, TPPP3 protein was found to be predominantly expressed in the mid-secretory phase (LH+7). In the primary culture of human endometrial stromal cells (hESCs), TPPP3 siRNA knockdown inhibited stromal-to-decidual cell transition and decreased the expression of the decidualization markers prolactin and IGFBP-1. Immunofluorescence and immunoblotting experiments revealed that TPPP3 siRNA knockdown suppressed the expression of ß-catenin, NF-κB and COX-2 in hESCs during decidualization. TPPP3 inhibition also decreased NF-kB nuclear accumulation in hESCs and suppressed NF-κB transcriptional promoter activity. COX-2 expression was significantly decreased in the presence of a selective NF-kB inhibitor (QNZ) implicating that NF-kB is involved in COX-2 expression in hESCs undergoing decidualization. TUNEL assay and FACS analysis revealed that TPPP3 knockdown induced apoptosis and caused loss of mitochondrial membrane potential in hESCs. The study suggested that TPPP3 plays a significant role in decidualization and its inhibition leads to the suppression of ß-catenin/NF-κB/COX-2 signaling along with the induction of mitochondria-dependent apoptosis.

RESUMO

Hh/Gli1 cascade as well as Gsk3ß-Gli1 crosstalk play crucial role in estrogen-dependent progression of endometrial hyperplasia (EH). However, the underlying mechanisms involved in progression of disease still remain unclear. In the present study, we explored the role of Hh signaling in protection of endometrial hyperplasial cells against oxidative stress and the underlying mechanism involved therein. EH cells were found to be more resistant towards H2O2-induced oxidative stress (IC50: ~ 3×) as compared with normal endometrial cells. Estrogen (E2) pre-treatment followed by cytotoxic dose of H2O2, almost rescued the EH cells from apoptosis and caused the increased expression of downstream Shh signaling molecules i.e., Smo, Ptch and Gli1. Whereas pretreatment with cyclopamine was not able to curtail H2O2-induced effects indicating that estrogen protects these cells via activation of Shh pathway. Further, H2O2-induced ROS and lipid peroxidation alongwith decreased activities of antioxidant enzymes glutathione peroxidase and superoxide dismutase were found to be reversed in EH cells pre-exposed to E2 or rShh. The rShh suppressed H2O2-induced cell death and caused attenuation of mitochondrial apoptotic mediators and prevented disruption in mitochondrial morphology and mitochondrial membrane potential in EH cells. The functional blockage of signaling by Shh siRNA or Gli1siRNA led to significantly increased expression of mitochondrial fission protein dynamin-like GTPase (Drp1). The H2O2-treated EH cells showed diminished Gli1 and increased Drp1 expression, concurrent with reduced p-Drp1-(serine637). Whereas rShh pre-treated EH cells presented normal mitochondrial dynamics with dense, long networks of mitochondria alongwith nuclear accumulation of Gli1 and the decreased expression of Drp1. Overall, our results implicated that Shh signaling modulates antioxidant defense system and stabilizes mitochondrial dynamics by suppressing Drp1 protein which maintains survival of EH cells against oxidative stress.

RESUMO

The present study was undertaken to explore the functional involvement of Hh signaling and its regulatory mechanism in endometrial hyperplasia. Differential expression of Hh signaling molecules i.e., Ihh, Shh, Gli1 or Gsk3ß was observed in endometrial hyperplasial (EH) cells as compared to normal endometrial cells. Estradiol induced the expression of Hh signaling molecules and attenuated the expression of Gsk3ß whereas anti-estrogen (K1) or progestin (MPA) suppressed these effects in EH cells. Cyclopamine treatment or Gli1 siRNA knockdown suppressed the growth of EH cells and reduced the expression of proliferative markers. Estradiol also induced the nuclear translocation of Gli1 which was suppressed by both MPA and K1 in EH cells. While exploring non-canonical mechanism, LY-294002 (Gsk3ß activator) caused a decrease in Gli1 expression indicating the involvement of Gsk3ß in Gli1 regulation. Further, Gsk3ß silencing promoted the expression and nuclear translocation of Gli1 demonstrating that Gsk3ß serves as a negative kinase regulator of Gli1 in EH cells. Similar attenuation of Hh signaling molecules was observed in rats with uterine hyperplasia undergoing anti-estrogen treatment. The study suggested that Hh/Gli1 cascade (canonical pathway) as well as Gsk3ß-Gli1 crosstalk (non-canonical pathway) play crucial role in estrogen-dependent cell proliferation in endometrial hyperplasia.

RESUMO

Although curcumin shows anti-proliferative and anti-inflammatory activities in various cancers, the effect of curcumin on cellular migration in endometrial adenocarcinoma cells remains to be understood. The current investigation was aimed to explore the anti-proliferative and anti-migratory effects of curcumin and its mechanism of action in endometrial cancer cells. Our in-vitro and in-vivo experimental studies showed that curcumin inhibited the proliferation of endometrial cancer cells and suppressed the tumor growth in Ishikawa xenograft mouse model. Curcumin induced ROS-mediated apoptosis in endometrial cancer cells. Curcumin suppressed the migration rate of Ishikawa and Hec-1B cells as analyzed by scratch wound assay. In transwell migration studies, knock down of Slit-2 reversed the anti-migratory effect of curcumin in these cell lines. Curcumin significantly up-regulated the expression of Slit-2 in Ishikawa, Hec-1B and primary endometrial cancer cells while it down-regulated the expression of stromal cell-derived factor-1 (SDF-1) and CXCR4 which in turn, suppressed the expression of matrix metallopeptidases (MMP) 2 and 9, thus attenuating the migration of endometrial cancer cells. In summary, we have demonstrated that curcumin has inhibitory effect on cellular migration via Slit-2 mediated down-regulation of CXCR4, SDF-1, and MMP2/MMP9 in endometrial carcinoma cells. These findings helped explore the role of Slit-2 in endometrial cancer cells.

RESUMO

Epithelial ovarian cancer (EOC) is the leading cause of death among all gynecological malignancies. Despite the technological and medical advances over the past four decades, such as the development of several biological markers (mRNA and proteins biomarkers), the mortality rate of ovarian cancer remains a challenge because of its late diagnosis, which is specifically attributed to low specificities and sensitivities. Under this compulsive scenario, recent advances in expression biology have shifted in identifying and developing specific and sensitive biomarkers, such as microRNAs (miRNAs) for cancer diagnosis and prognosis. MiRNAs are a novel class of small non-coding RNAs that deregulate gene expression at the posttranscriptional level, either by translational repression or by mRNA degradation. These mechanisms may be involved in a complex cascade of cellular events associated with the pathophysiology of many types of cancer. MiRNAs are easily detectable in tissue and blood samples of cancer patients. Therefore, miRNAs hold good promise as potential biomarkers in ovarian cancer. In this review, we attempted to provide a comprehensive profile of key miRNAs involved in ovarian carcinoma to establish miRNAs as more reliable non-invasive clinical biomarkers for early detection of ovarian cancer compared with protein and DNA biomarkers.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Indian systems of medicine use roots of Withania somnifera for impotence, infertility treatment, stress, and the aging process. Although Withania somnifera improves semen quality by regulating reproductive hormone levels and oxidative stress, the molecular mechanism is not clear. AIM OF THE STUDY: Our study uses high-resolution Nuclear Magnetic Resonance (NMR) spectroscopy to explore the scientific basis to reveal the pre- and post-treatment efficacy of Withania somnifera on seminal plasma of infertile men-which remains unexplored to date. MATERIALS AND METHODS: A total of 180 infertile male patients were administered Withania somnifera root powder at the rate of 5 g/d for a 3-month period. The study included age-matched, healthy men as a control (n=50) group. Proton NMR spectroscopy was used to measure lactate, alanine, glutamate, glutamine, citrate, lysine, choline, glycerophosphocholine (GPC), glycine, tyrosine, histidine, phenylalanine, and uridine in all seminal plasma samples. To appraise infertility levels, we also measured sperm concentration, motility, lipid peroxide, and hormonal perturbation. RESULTS: Withania somnifera therapy repairs the disturbed concentrations of lactate, alanine, citrate, GPC, histidine, and phenylalanine in seminal plasma and recovers the quality of semen of post-treated compared to pre-treated infertile men. Serum biochemistry was also improved over post-therapy in infertile men. Our findings reveal that Withania somnifera not only reboots enzymatic activity of metabolic pathways and energy metabolism but also invigorates the harmonic balance of seminal plasma metabolites and reproductive hormones in infertile men. CONCLUSION: The results suggest that Withania somnifera may be used as an empirical therapy for clinical management and treatment of infertility.

RESUMO

OBJECTIVE: A prospective cohort study in a teaching hospital to assess the efficacy and safety of neoadjuvant chemotherapy in the treatment of locally advanced carcinoma cervix. METHOD: Neoadjuvant chemotherapy in the form of cisplatin 75 mg/m(2) and paclitaxel 135 mg/m(2) on day 1 and repeated at 14 days' interval for up to a maximum of three courses. RESULTS: Neoadjuvant chemotherapy in cervical cancer was effective in the downstaging of the disease. Downstaging was observed in 19.23 % of patients after two cycles and in 50 % of patients after three cycle of NACT. Operability increases to 33.3 and 38.4 % after two and three cycles of NACT, respectively. Complete pathological response was observed in 37.5 % of patients after NACT. No significant adverse effect in the feasibility of surgery was observed. CONCLUSION: The present study showed that neoadjuvant chemotherapy was an effective and well-tolerated mode of therapy with significantly less morbidity and mortality.

RESUMO

BACKGROUND: Benign prostatic hyperplasia (BPH) is an age related non-malignant disease diagnosed as lower urinary tract symptoms and prostatic enlargement. Null genotypes in drug detoxification glutathione-S-transferase genes/enzymes, such as GSTT1 and GSTM1 have been reported to increase risk of several cancers including prostate. Meta-analysis on PC also suggested significant impact of GSTM1 null genotype but not that of GSTT1; however, BPH data have not been subjected to meta-analysis. METHODS: We investigated GSTT1 and GSTM1 genotypes in 429 subjects which included 244 BPH, 51 prostate cancer (PC) patients, and 134 control subjects to find if null genotype in any of the two genes increased the risk of BPH/PC. We also performed a quantitative meta-analysis on 888 BPH cases and 793 controls for GSTM1 and on 890 BPH cases and 793 controls for GSTT1 to assess overall consensus about the impact of null genotypes on BPH risk. RESULTS: We did not find any significant difference in the distribution of genotypes of either of the two genes between BPH/PC cases and controls; however, double deletion (GSTM1 null + GSTT1 null) increased BPH risk, significantly. Upon meta-analysis, null genotype of GSTM1 but not that of GSTT1 appeared to strongly affect BPH risk. CONCLUSIONS: In our population, null genotypes of either GSTM1 or GSTT1 do not appear to affect BPH risk; however, the double deletion was significantly associated with BPH. Meta-analysis suggested significant influence of GSTM1 null genotype but not that of GSTT1 on BPH risk.
