Ssedyabane F, Ngonzi J, Kajabwangu R, Najjuma JN, Tusubira D, Randall TC. Association between obesity and cervical intraepithelial neoplasia: results from a case control study in south western Uganda. BMC Womens Health 2023; 23:159. [PMID: 37016401 PMCID: PMC10074666 DOI: 10.1186/s12905-023-02315-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 03/29/2023] [Indexed: 04/06/2023] Open
Abstract
BACKGROUND Though obesity has been said to be associated with a number of malignancies including cervical cancer, its association with cervical intraepithelial neoplasia (CIN) is still a contentious issue. This study was designed to determining the prevalence and association between obesity and CIN. METHODS This was an unmatched case control study, involving women with cervical intraepithelial neoplasia (cases) and those negative for intraepithelial lesions or malignancy (controls) at the cervical cancer clinic of Mbarara Regional Referral Hospital, in south-western Uganda, between April and November 2022. Cases and controls provided written informed consent and were recruited in a ratio of 1:1. Cases were identified by visual inspection with acetic acid (VIA) and subsequent confirmation with cytology and/or histology. Demographic information was collected using an enrolment form and height, weight and waist circumference were recorded. We calculated body mass index (BMI) and identified obese women as those with body mass index of ≥ 30 kg/m2 from both case and control groups. Central obesity was defined as waist: height ration of ≥ 0.5. Data was analysed using STATA version 17. Categorical variables were analysed using proportions, chi-square and logistic regression analysis to determine association between obesity and CIN. Our level of statistical significance was set at ≤ 0.05. RESULTS The prevalence of general and central obesity among cases was 25.5% (24/94) and 0% (0/94) respectively while the prevalence of general and central obesity among controls was 33.3% (37/111) and 0% (0/111) respectively. There was an increased prevalence of general obesity among women with low grade squamous intraepithelial lesions (LSIL). However, there was no statistically significant association between general obesity and CIN. Factors associated with general obesity included residing in Mbarara city (AOR 2.156, 95%CI 1.085-4.282, P-value 0.028), age group of 31-45 years (AOR 2.421, 95%CI 1.577-9.705, P-value 0.003) and ≥ 46 years (AOR 1.971, 95%CI 1.022-11.157, P-value 0.046). CONCLUSION We observed an increased prevalence of general obesity among women with LSIL. However, there was no association between obesity and CIN. Factors associated with general obesity included residing in Mbarara city, and being in the age groups of 31-40 and ≥ 46 years. This highlights the need to rethink management of CIN to control other non-communicable diseases that could arise due to general obesity.

Progression Free Survival, Overall Survival, and Relapse Rate in Endometrioid Ovarian Cancer and Synchronous Endometrial-Ovarian Endometrioid Cancer (SEO-EC): Results from a Large Retrospective Analysis. Medicina (B Aires) 2022; 58:medicina58121706. [PMID: 36556908 PMCID: PMC9784653 DOI: 10.3390/medicina58121706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 11/14/2022] [Accepted: 11/21/2022] [Indexed: 11/24/2022] Open
Abstract
Background and Objectives: We aimed to evaluate Progression Free Survival (PFS), Overall Survival (OS), and relapse rate in women affected by endometrioid ovarian cancer and synchronous endometrial-ovarian endometrioid cancer (SEO-EC). As secondary outcome, we assessed whether systematic pelvic and para-aortic lymphadenectomy could be considered a determinant of relapse rate in this population. Materials and Methods: We performed a retrospective analysis of women with diagnosis of endometrioid ovarian cancer or SEO-EC between January 2010 to September 2020, and calculated PFS, OS and relapse rate. Results: In almost all the patients (97.6%) who underwent systematic pelvic and para-aortic lymphadenectomy, there were no lymph node metastases confirmed by histology. We did not find a significant difference (p = 0.6570) for the rate of relapse in the group of women who underwent systematic pelvic and para-aortic lymphadenectomy (4/42; 9.5%) compared with the group of women who did not undergo the same procedure (1/21; 4.8%). During a median follow-up was 23 months, both PFS and OS were excellent. Conclusions: Women affected by early-stage low-grade endometrioid cancer and SEO-EC without apparent lymph node involvement at pre-operative imaging showed a very low rate of lymph node metastasis and similar relapse rate with or without lymphadenectomy.

Metabolic Syndrome as a Risk Factor of Endometrial Cancer: A Nationwide Population-Based Cohort Study of 2.8 Million Women in South Korea. Front Oncol 2022; 12:872995. [PMID: 35785211 PMCID: PMC9243219 DOI: 10.3389/fonc.2022.872995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/04/2022] [Indexed: 12/02/2022] Open
Abstract
Background A positive relationship was reported between metabolic syndrome and the risk of endometrial cancer. Studies on the relationship between metabolic syndrome and endometrial cancer have been mainly conducted in post-menopausal women. We aimed to investigate the risk of endometrial cancer according to metabolic syndrome and menopausal status using the Korean nationwide population-based cohort. Methods We enrolled 2,824,107 adults (endometrial cancer group; N = 5,604 and control group; N= 2,818,503) from the Korean National Health Insurance Service checkup database from January 1 to December 31, 2009. The median follow-up duration was 8.37 years. Metabolic syndrome was diagnosed as having at least three of the following five components: abdominal obesity, hypertriglyceridemia, low levels of high-density lipoprotein cholesterol, raised blood pressure, and hyperglycemia. Multivariate Cox proportional hazard models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs) to estimate endometrial cancer risk. Results The endometrial cancer risk was higher in the metabolic syndrome group than that in the non-metabolic syndrome group (HR, 1.362; 95% CI, 1.281–1.449). The association between metabolic syndrome and endometrial cancer risk was significant in the premenopausal subgroup (HR, 1.543; 95% CI, 1.39–1.713) and postmenopausal subgroup (HR, 1.306; 95% CI, 1.213–1.407). The incidence of endometrial cancer was more closely related to metabolic syndrome components in the pre-menopausal subgroup than those in the post-menopausal subgroup (for waist circumference, blood pressure, triglycerides and high-density lipoprotein cholesterol, all p for interaction <0.0001 respectively, and for fasting blood glucose, p for interaction 0.0188). The incidence of endometrial cancer positively correlated with the number of metabolic syndrome components (log-rank p <0.0001). Conclusion Our large population-based cohort study in Korean women suggests that metabolic syndrome and its accumulated components may be risk factors for endometrial cancer, particularly in the pre-menopausal women.

Abstract
Background: Breast and cervical cancer screening are responsible for dramatically reducing cancer deaths. Overweight and obesity are associated with deleterious health outcomes, including increased risk of developing cancer. This study adds to the existing literature examining the association of having overweight and obesity and receipt of breast or cervical cancer screening. Methods: Using the 2013 Brazos Valley Community Health Needs Assessment, we examined the association between body mass index (BMI) and receipt of breast or cervical cancer screening among women meeting age recommendations for breast cancer and cervical cancer screening (n = 1979 and n = 2040), respectively. We used SPSS 22 statistical software for descriptive and logistic regression analysis. Results: Overall, 26.6% of women missed the breast cancer screening guidelines, and 13.3% missed the cervical cancer screening guidelines. BMI had a weak association with missing cervical cancer screenings (odds ratio [OR] = 1.02; confidence interval [CI] = 1.01–1.04), but no association with missing breast cancer screenings (OR = 1.01; CI = 0.99–1.03). Higher age, race (non-White), rural area, no health insurance, smoking, and delayed health care were associated with missing breast cancer screenings. Higher age, marital status (single), lower education, no health insurance, smoking, and delayed health care were associated with missing cervical cancer screening. Further research is needed to better understand the association using larger, more diverse samples.

Abstract
OBJECTIVES The aims of the study were to identify whether obese women are less appropriately screened for cervical cancer before diagnosis and to explore related cancer outcomes. METHODS We retrospectively reviewed all cervical cancer patients at a single institution between 1986 and 2016 and collected demographic information including age, cancer stage, body mass index (BMI), screening information, and cancer outcomes. Morbid obesity was defined as BMI of 40 kg/m or greater, obesity as BMI of 30 to less than 40 kg/m, and nonobese as BMI of less than 30 kg/m. χ, Fisher exact, and Wilcoxon rank sum tests were used to compare variables between BMI categories. Cox regression models were used to evaluate recurrence-free survival and overall survival (OS). RESULTS A total of 1,080 patients were reviewed, of whom 311 (29.4%) were obese and 107 (10.1%) morbidly obese. A significant association between BMI and cytology screening was evidenced with morbidly obese women having the highest incorrect rate (64.4%), followed by obese (51.5%) and nonobese women (46.0%, p < .01). There was no significant difference in presence of symptoms at presentation (p = .12) or stage (p = .06) between BMI categories. In multivariable analysis of cancer outcomes, higher BMI was associated with worse OS (p < .01) with a hazard ratio of 1.25 (95% CI = 0.92-1.69) for obese women and hazard ratio 2.27 (95% CI = 1.56-3.31) for morbidly obese women relative to normal weight but recurrence-free survival did not differ between BMI groups (p = .07). CONCLUSIONS Our study strengthens evidence that obese and morbidly obese women have disproportionate inappropriate screening before cervical cancer diagnosis, and morbidly obese women have worse OS than their counterparts.

Abstract
Background The mechanisms underlying the association between obesity and coronavirus disease 2019 (COVID-19) severity remain unclear. After verifying that obesity was a correlate of severe COVID-19 in US Military Health System (MHS) beneficiaries, we compared immunological and virological phenotypes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in both obese and nonobese participants. Methods COVID-19–infected MHS beneficiaries were enrolled, and anthropometric, clinical, and demographic data were collected. We compared the SARS-CoV-2 peak IgG humoral response and reverse-transcription polymerase chain reaction viral load in obese and nonobese patients, stratified by hospitalization, utilizing logistic regression models. Results Data from 511 COVID-19 patients were analyzed, among whom 24% were obese and 14% severely obese. Obesity was independently associated with hospitalization (adjusted odds ratio [aOR], 1.91; 95% confidence interval [CI], 1.15–3.18) and need for oxygen therapy (aOR, 3.39; 95% CI, 1.61–7.11). In outpatients, severely obese had a log10 (1.89) higher nucleocapsid (N1) genome equivalents (GE)/reaction and log10 (2.62) higher N2 GE/reaction than nonobese (P = 0.03 and P < .001, respectively). We noted a correlation between body mass index and peak anti-spike protein IgG in inpatients and outpatients (coefficient = 5.48, P < .001). Conclusions Obesity is a strong correlate of COVID-19 severity in MHS beneficiaries. These findings offer new pathophysiological insights into the relationship between obesity and COVID-19 severity.

Abstract
Worldwide, cervical cancer was the fourth leading cause of cancer death among women, while in Mexico was the second cause (5.28%). Cancer patients receiving chemotherapy and radiotherapy have a high risk of malnutrition secondary to the disease and treatment, affects the patient's overall, with adverse effects on gastrointestinal symptoms. These use affects the medical therapy. The aim of the present study was to evaluate the benefits on individualized nutritional therapy on decrease weight loss and gastrointestinal adverse effects and to consider these outcomes in pharmacology research, especially in repurposing drugs. We conducted a longitudinal design with two comparation groups with medical diagnosis of cervical cancer and received radiotherapy weekly, 1) the intervention group (nutritional intervention and counseling -INC-) with 20 participants and 2) control group (retrospective cohort -CG-) with 9 participants. Weekly body composition, dietary intake, adverse effects (gastrointestinal symptoms), glucose, hemoglobin, and blood pressure were analyzed during 4 to 5 weeks. Both groups had weight loss weekly (p = 0.013 and p = 0.043 respectively) but the CG vs INC presented loss fat-free mass ≥500g in 67 and of 37% respectively. By the end of the intervention a 25% of the INC group had <10 g/dL of hemoglobin vs 60% for the CG. To compare the dietary intake of vitamins (A and folic acid), fiber (p = 0.006), iron (p = 0.03) and energy (mainly carbohydrates) (p = 0.04) were according to the recommendations in INC group (p>0.05). The number needed to treat was 4 (95% CI, 2 to 13). The nutritional intervention and counseling weekly during radiotherapy in cervical cancer to maintain/improve muscle mass, hemoglobin, and dietary intake above 70% of the recommendations for INC group compared to the evidence. Adequate nutritional status was maintained and decrease the rate of complications, mainly gastrointestinal symptoms, in INC group. The efficacy of drug repurposing can improve through individualized nutritional therapy for preventing adverse effects of radiotherapy in patients with cervical cancer.

Abstract
Obesity, characterized by excess body weight, is now accepted as a hazardous health condition and an oncogenic factor. In different epidemiological studies obesity has been described as a risk factor in several malignancies. Some biological mechanisms that orchestrate obesity-cancer interaction have been discovered, although others are still not completely understood. The unbalanced secretion of biomolecules, called "adipokines", released by adipocytes strongly influences obesity-related cancer development. Among these adipokines, adiponectin exerts a critical role. Physiologically adiponectin governs glucose levels and lipid metabolism and is fundamental in the reproductive system. Low adiponectin circulating levels have been found in obese patients, in which its protective effects were lost. In this review, we summarize the epidemiological, in vivo and in vitro data in order to highlight how adiponectin may affect obesity-associated female cancers.

Abstract
Background: Breast cancer is the most common cancer among women worldwide and the obesity is one of
the factors related to the risk of breast cancer mainly in postmenopausal women. This study investigated the association
between obesity in pre- and postmenopausal women with the development of breast cancer and the expression of
estrogen, progesterone, HeR-2 and triple-negative (TN) receptors. Methods: A case-control study was conducted
on 100 patients with recently diagnosed breast cancer and 400 age-matched controls. The women were divided into
pre- and post-menopausal groups. Results: The multivariate analysis showed that postmenopausal women with
a BMI ≥ 30 kg/m2 at pre-diagnosis and at the most recent measurement were 1.50 (95% CI 1.06-2.13) and 1.56
(95% CI 1.11-2.21) times more likely to develop breast cancer, respectively. These women had a prevalence of
obesity of 27.7% when considering pre-diagnosis BMI and 29.4% when analyzing the indicator of recent BMI. When
only the cases regarding the presence of obesity with clinicopathological variables were analyzed, a total of 95.2% of
the postmenopausal women with pre-diagnostic obesity according to BMI presented the positive estrogen receptor
(ER) subtype. Conclusions: In Brazilian women, there is an association between obesity and the risk of breast cancer
postmenopause; moreover, there is an association between the occurrence of the positive ER subtype in postmenopausal
women and pre-diagnostic obesity according to BMI.

Abstract
PURPOSE Higher mortality after a breast cancer diagnosis has been observed among women who are obese. We investigated the relationships between body mass index (BMI) and all-cause or breast cancer-specific mortality after a diagnosis of locoregional breast cancer. METHODS Women diagnosed in 2004 with AJCC Stage I, II, or III breast cancer (n = 5394) were identified from a population-based National Program of Cancer Registries (NPCR) patterns of care study (POC-BP) drawing from registries in seven U.S. states. Differences in overall and breast cancer-specific mortality were investigated using Cox proportional hazards regression models adjusting for demographic and clinical covariates, including age- and stage-based subgroup analyses. RESULTS In women 70 or older, higher BMI was associated with lower overall mortality (HR for a 5 kg/m2 difference in BMI = 0.85, 95% CI 0.75-0.95). There was no significant association between BMI and overall mortality for women under 70. BMI was not associated with breast cancer death in the full sample, but among women with Stage I disease; those in the highest BMI category had significantly higher breast cancer mortality (HR for BMI ≥ 35 kg/m2 vs. 18.5-24.9 kg/m2 = 4.74, 95% CI 1.78-12.59). CONCLUSIONS Contrary to our hypothesis, greater BMI was not associated with higher overall mortality. Among older women, BMI was inversely related to overall mortality, with a null association among younger women. Higher BMI was associated with breast cancer mortality among women with Stage I disease, but not among women with more advanced disease.

Abstract
Obesity is a common serious health problem leading to many serious health disorders. This phenomenon is defined as the over-storage of lipids in adipose tissue that occurs when there is an imbalance between the energy intake and energy used. During obesity, many metabolic alterations occur that can damage several organs, such as vascular or skeletal muscle resulting in the dysfunction of these tissues. In this review, we will discuss molecular genetics and causes of obesity, some of the disorders related to human obesity as well as anti-obesity tool. An interesting solution to the obesity problem is natural substances, revealing anti-obesity activity, as well as functional food enriched with aforementioned substances. Functional foods are products exhibiting a potentially positive effect on health beyond basic nutrition. They contain well-known biologically active natural compounds, which promote optimal health and reduce the risk of many diseases, including obesity.

Abstract
Phosphoramide mustard (PM) destroys rapidly dividing cells and activates the DNA double strand break marker, γH2AX, and DNA repair in rat granulosa cells and neonatal ovaries. The effects of PM exposure on DNA damage and activation of DNA damage repair in lean and obese female mice were investigated. Wild type (lean) non agouti (a/a) and KK.Cg-Ay/J heterozygote (obese) mice received sesame oil or PM (95%; 25 mg/kg; intraperitoneal injection). Obesity increased (P < 0.05) hepatic and spleen but decreased (P < 0.05) uterine weight. PM exposure reduced (P < 0.05) spleen weight regardless of body composition, however, decreased (P < 0.05) ovarian and hepatic weight were observed in the obese PM-exposed females. PM decreased (P < 0.05) primordial and primary follicle number in lean females. Obesity and PM increased (P < 0.05) γH2AX protein. DNA damage repair genes Prkdc, Parp1, and Rad51 mRNA were unaltered by obesity, however, Atm and Xrcc6 mRNA were increased (P < 0.05) while Brca1 was reduced (P < 0.05). Obesity reduced (P < 0.05) PRKDC, XRCC6 and but increased (P < 0.05) ATM protein. ATM, BRCA1 and RAD51 protein levels were increased (P < 0.05) by PM exposure in both lean and obese mice, while PM-induced increased (P < 0.05) XRCC6 and PARP1 were observed only in lean mice. Thus, PM induces ovarian DNA damage in vivo; obesity alters DNA repair response gene mRNA and protein level; the ovary activates DNA repair proteins in response to PM; but obesity compromises the ovarian PM response.

Abstract
The association between obesity and ovarian cancer risk has been extensively investigated, but studies have yielded inconsistent findings. This review aims to summarise and discuss the evidence generated to date. Articles published in English prior to August 2016 were retrieved from PubMed. Keywords included obesity, overweight, body size, body mass index, waist-hip ratio, waist circumference, body weight, ovarian cancer, ovarian carcinoma, ovarian neoplasm, and ovarian tumour. Eligible studies compared two or more groups of women, with at least one group in the overweight or obese category and one comprising normal weight controls. Summary data in the form of relative risk, hazard ratio, or odds ratio for each comparison group from individual studies were collated and reviewed. Forty-three studies were included in the final analysis, with a total of 3,491,943 participants. All studies included body mass index as an exposure measure, and a majority relied on self-reported measures from participants; 14 studies found a statistically significant positive association between ovarian cancer risk and higher body mass index, 26 studies found no significant association, and 3 studies found a negative association between ovarian cancer risk and higher body mass index. This review concludes that there is limited, inconsistent evidence of a positive association between obesity and ovarian cancer risk.

Abstract
OBJECTIVE To compare complications and outcomes after hysterectomy for benign compared with malignant indications in the United States. METHODS Women who underwent hysterectomy in the United States for either benign or malignant indications from January 2008 to December 2012 were retrospectively identified using the National Surgical Quality Improvement Program database. Patients were excluded if the procedure was not performed for primary gynecologic indications. Appropriate procedures were identified using Current Procedural Terminology and International Classification of Diseases, 9th Revision codes. Univariate and multivariable models for complication risk were estimated using logistic regression. RESULTS We identified 59,525 eligible patients, with 49,331 (82.9%) hysterectomies performed for benign and 10,194 (17.1%) for malignant indications. All complications, including wound complications (2.5% benign compared with 5.5% malignant, P<.001), venous thromboembolism (0.33% compared with 1.7%, P<.001), urinary tract infection (2.7% compared with 3.2%, P=.009), sepsis (0.53% compared with 1.9%, P<.001), blood transfusion (2.6% compared with 11.5%, P<.001), death (0.02% compared with 0.10%, P<.001), unplanned readmission (1.8% compared with 4.5%, P<.001), and returns to the operating room (0.91% compared with 1.4%, P<.001), were significantly more common for malignant hysterectomies. The overall rate of complications for benign cases was 7.9% compared with a rate of 19.4% for malignant hysterectomy. The median operating time for laparoscopy in benign cases was significantly longer than for open or vaginal hysterectomy procedures (127 minutes compared with 105 or 94 minutes, respectively; P<.001). The median operating time in malignant cases was significantly longer than for benign cases (P<.001). CONCLUSION Hysterectomies performed for gynecologic malignancies are associated with a more than twofold higher complication rate compared with those performed for benign conditions. Minimally invasive surgery is associated with a decreased complication rate compared with open surgery. These data can be used for patient counseling and surgical planning, determining physician and hospital costs of care, and considered when assigning value-based reimbursement.

Abstract
The aim of this study was to compare the financial and clinical outcomes in robotic-assisted laparoscopic surgery for primary endometrial cancer between obese and nonobese women. The hospital finance department assessed the total admission costs for robotic surgery for endometrial cancer in 54 women. This included a subanalysis for costs over nine areas (ward and clinics, drugs and pharmacy, medical staff, theaters, blood products, imaging, pathology, rehabilitation therapy, and high dependency costs). Furthermore, a prospective collection of morbidity and surgical outcome data was performed. The study group included 21 nonobese and 33 obese women (body mass index >30). Obese women were more likely to stay for more than one night in hospital (20/33 [60.6%] compared to 4/21 [19.0%], P=0.032) and to have high dependency care (25/33 [75.8%] compared to 10/21 [47.6%], P=0.032). Theater time was on average 35 min longer (95% confidence interval [CI] 5–65 min, P=0.0252). Both the groups were comparable for comorbidities except for the presence of diabetes being present in the obese group (13/33 [39.4%] compared to 0/21 [0.0%], P=0.007). There were six Clavien-Dindo grade II complications in the obese group and two in the nonobese group. The average overall costs were £1,852 greater (95% CI £431–£3,277, P=0.012) in the obese group. Diabetes and hypertension were associated with increased costs, but obesity was the only independent variable. In conclusion, greater resource should be allocated to obese women undergoing primary surgery for endometrial cancer.

Abstract
OBJECTIVE The aim of this study was to evaluate outcomes of patients with breast cancer in function of the body mass index (BMI). METHODS The study cohort consisted of consecutive women undergoing surgery for breast cancer in our institution between January 2009, and September 2013. Individual records of all patients were reviewed and analyzed. Patient BMI was categorized as underweight, normal, overweight and obese. RESULTS A total of 1599 patients were evaluated. Patients were followed for one to 265months with a mean of 36.4months. The number of patients in each of the BMI categories was 66, 779, 463 and 291 for underweight, normal, overweight and obese women respectively. Women with higher BMI were more frequently affected by hypertension (18, 21, 35 and 47% respectively, P<0.0001) and diabetes (3, 2, 7 and 7% respectively, P<0.0001). Obese women had more frequently an inflammatory presentation (P=0.006), larger tumour size (P=0.038) and axillary lymph node involvement (P=0.03) with much more positive lymph nodes (P=0.02). Patients had the same protocols of treatment (surgery and adjuvant treatment). There was no statistically significant difference in overall 5-years survival between groups (P=0.30). CONCLUSIONS Our study demonstrate a more aggressive clinical and histological presentation for obese women with breast cancer.

Abstract
Previous studies have shown that leptin, an adipocyte-secreted hormone, stimulates ovarian cancer invasion. Here, we investigated the contribution of uPA in leptin-induced ovarian cancer cell invasion. The cell invasion and migration experiments were carried out using matrigel invasion and wound healing assays in ovarian cancer cell lines (OVCAR3, SKOV3and CaoV-3). The mechanism underlying the invasive effect of leptin was examined using cell transfection with Ob-Rb siRNA, pre-treatment with a specific inhibitor of RhoA and ROCK, RhoA activation assay, OB-Rb, Rock and upA protein expression. Our results show that leptin induced ovarian cancer cell invasion via up-regulating upA in a time and dose-dependent manner, which was attenuated using knockdown of OB-Rb by siRNA. Moreover, pre-incubation with C3 (inhibitor of RhoA) and Y-27632 (inhibitor of ROCK) effectively attenuated leptin-induced upA expression and inhibited invasive ability of ovarian cancer cells. We also found that pretreatment with inhibitors of PI3K/AKT (LY294002), JAK/STAT (AG490) and NF-kB (BAY 11-7082) significantly reduced leptin-induced upA expression. Collectively, our findings demonstrate that OB-Rb, RhoA/ROCK, PI3K/AKT, JAK/STAT pathways and NF-kB activation are involved in leptin-induced upA expression. These results may provide a new mechanism that facilitates leptin-induced ovarian cancer invasion.

Abstract
Obesity and its related health complications is a major problem worldwide. Hypothalamus and their signalling molecules play a critical role in the intervening and coordination with energy balance and homeostasis. Genetic factors play a crucial role in determining an individual's predisposition to the weight gain and being obese. In the past few years, several genetic variants were identified as monogenic forms of human obesity having success over common polygenic forms. In the context of molecular genetics, genome-wide association studies (GWAS) approach and their findings signified a number of genetic variants predisposing to obesity. However, the last couple of years, it has also been noticed that alterations in the environmental and epigenetic factors are one of the key causes of obesity. Hence, this review might be helpful in the current scenario of molecular genetics of human obesity, obesity-related health complications (ORHC), and energy homeostasis. Future work based on the clinical discoveries may play a role in the molecular dissection of genetic approaches to find more obesity-susceptible gene loci.

Abstract
Obesity represents a major under-recognized preventable risk factor for cancer development and recurrence, including breast cancer (BC). Healthy diet and correct lifestyle play crucial role for the treatment of obesity and for the prevention of BC. Obesity is significantly prevalent in western countries and it contributes to almost 50% of BC in older women. Mechanisms underlying obesity, such as inflammation and insulin resistance, are also involved in BC development. Fatty acids are among the most extensively studied dietary factors, whose changes appear to be closely related with BC risk. Alterations of specific ω-3 polyunsaturated fatty acids (PUFAs), particularly low basal docosahexaenoic acid (DHA) levels, appear to be important in increasing cancer risk and its relapse, influencing its progression and prognosis and affecting the response to treatments. On the other hand, DHA supplementation increases the response to anticancer therapies and reduces the undesired side effects of anticancer therapies. Experimental and clinical evidence shows that higher fish consumption or intake of DHA reduces BC cell growth and its relapse risk. Controversy exists on the potential anticancer effects of marine ω-3 PUFAs and especially DHA, and larger clinical trials appear mandatory to clarify these aspects. The present review article is aimed at exploring the capacity of DHA in controlling obesity-related inflammation and in reducing insulin resistance in BC development, progression, and response to therapies.

Abstract
Tumor susceptibility gene 101 (TSG101) and activating transcription factor 2 (ATF2) have been suggested to involve in the reactivation of EBV which has implications in the development and progression of breast cancer. Therefore, the polymorphisms of TSG101 and ATF2 may associate with breast cancer risk and prognosis. A case-control study with 1551 breast cancer cases and 1605 age-matched controls were conducted in Guangzhou, China. We have also successfully followed up 1168 cases until December 31, 2014. The variant allele of TSG101 rs2292179 was associated with a non-significant reduced risk of breast cancer, particularly among women with BMI < 24 (kg/m(2)) (P for interaction <0.05). For ATF2 rs3845744, the variant allele was also associated with a significantly reduced breast cancer risk [odds ratio (OR) (95 % confidence interval (CI)) 0.86 (0.74∼1.00)], and the association occurred among only postmenopausal women [OR (95 % CI) 0.69 (0.54∼0.88)] (P for interaction <0.05). Breast cancer risk was further reduced with the increasing numbers of the variant G alleles of the two polymorphisms (P for trend <0.05). We did not find an overall association of the two loci with breast cancer prognosis, while the hazard ratios of the two loci (AG/GG vs. AA) were significantly higher among postmenopausal women than premenopausal women (P = 0.046, 0.016 for TSG101 rs2292179 and ATF2 rs3845744, respectively). In summary, the variant alleles of TSG101 rs2292179 and ATF2 rs3845744 were associated with a reduced risk of breast cancer, particularly for subjects with BMI <24 (kg/m(2)) and postmenopausal women, respectively. The two SNPs and menopausal status may have a significant interaction on breast cancer progression.

Abstract
In recent years, the etiology of human disease has greatly improved with the inclusion of epigenetic mechanisms, in particular as a common link between environment and disease. However, for most diseases we lack a detailed interpretation of the epigenetic regulatory pathways perturbed by environment and causal mechanisms. Here, we focus on recent findings elucidating nutrient-related epigenetic changes linked to obesity. We highlight studies demonstrating that obesity is a complex disease linked to disruption of epigenetically regulated metabolic pathways in the brain, adipose tissue and liver. These pathways regulate (1) homeostatic and hedonic eating behaviors, (2) adipocyte differentiation and fat accumulation, and (3) energy expenditure. By compiling these data, we illustrate that obesity-related phenotypes are repeatedly linked to disruption of critical epigenetic mechanisms that regulate key metabolic genes. These data are supported by genetic mutation of key epigenetic regulators, and many of the diet-induced epigenetic mechanisms of obesity are also perturbed by exposure to environmental toxicants. Identifying similarly perturbed epigenetic mechanisms in multiple experimental models of obesity strengthens the translational applications of these findings. We also discuss many of the ongoing challenges to understanding the role of environmentally induced epigenetic pathways in obesity and suggest future studies to elucidate these roles. This assessment illustrates our current understanding of molecular pathways of obesity that are susceptible to environmental perturbation via epigenetic mechanisms. Thus, it lays the groundwork for dissecting the complex interactions between diet, genes and toxicants that contribute to obesity and obesity-related phenotypes.
