Abstract
Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance exercise training (ExT) and sex on its molecular landscape is not fully established. Utilizing an integrative multi-omics approach, and leveraging data generated by the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we show profound sexual dimorphism in the scWAT of sedentary rats and in the dynamic response of this tissue to ExT. Specifically, the scWAT of sedentary females displays -omic signatures related to insulin signaling and adipogenesis, whereas the scWAT of sedentary males is enriched in terms related to aerobic metabolism. These sex-specific -omic signatures are preserved or amplified with ExT. Integration of multi-omic analyses with phenotypic measures identifies molecular hubs predicted to drive sexually distinct responses to training. Overall, this study underscores the powerful impact of sex on adipose tissue biology and provides a rich resource to investigate the scWAT response to ExT.

Abstract
Regular exercise promotes whole-body health and prevents disease, but the underlying molecular mechanisms are incompletely understood1-3. Here, the Molecular Transducers of Physical Activity Consortium4 profiled the temporal transcriptome, proteome, metabolome, lipidome, phosphoproteome, acetylproteome, ubiquitylproteome, epigenome and immunome in whole blood, plasma and 18 solid tissues in male and female Rattus norvegicus over eight weeks of endurance exercise training. The resulting data compendium encompasses 9,466 assays across 19 tissues, 25 molecular platforms and 4 training time points. Thousands of shared and tissue-specific molecular alterations were identified, with sex differences found in multiple tissues. Temporal multi-omic and multi-tissue analyses revealed expansive biological insights into the adaptive responses to endurance training, including widespread regulation of immune, metabolic, stress response and mitochondrial pathways. Many changes were relevant to human health, including non-alcoholic fatty liver disease, inflammatory bowel disease, cardiovascular health and tissue injury and recovery. The data and analyses presented in this study will serve as valuable resources for understanding and exploring the multi-tissue molecular effects of endurance training and are provided in a public repository ( https://motrpac-data.org/ ).

Abstract
BACKGROUND In obesity, adipose tissue undergoes a remodeling process characterized by increased adipocyte size (hypertrophia) and number (hyperplasia). The ability to tip the balance toward the hyperplastic growth, with recruitment of new fat cells through adipogenesis, seems to be critical for a healthy adipose tissue expansion, as opposed to a hypertrophic growth that is accompanied by the development of inflammation and metabolic dysfunction. However, the molecular mechanisms underlying the fine-tuned regulation of adipose tissue expansion are far from being understood. METHODS We analyzed by mass spectrometry-based proteomics visceral white adipose tissue (vWAT) samples collected from C57BL6 mice fed with a HFD for 8 weeks. A subset of these mice, called low inflammation (Low-INFL), showed reduced adipose tissue inflammation, as opposed to those developing the expected inflammatory response (Hi-INFL). We identified the discriminants between Low-INFL and Hi-INFL vWAT samples and explored their function in Adipose-Derived human Mesenchymal Stem Cells (AD-hMSCs) differentiated to adipocytes. RESULTS vWAT proteomics allowed us to quantify 6051 proteins. Among the candidates that most differentiate Low-INFL from Hi-INFL vWAT, we found proteins involved in adipocyte function, including adiponectin and hormone sensitive lipase, suggesting that adipocyte differentiation is enhanced in Low-INFL, as compared to Hi-INFL. The chromatin modifier SET and MYND Domain Containing 3 (SMYD3), whose function in adipose tissue was so far unknown, was another top-scored hit. SMYD3 expression was significantly higher in Low-INFL vWAT, as confirmed by western blot analysis. Using AD-hMSCs in culture, we found that SMYD3 mRNA and protein levels decrease rapidly during the adipocyte differentiation. Moreover, SMYD3 knock-down before adipocyte differentiation resulted in reduced H3K4me3 and decreased cell proliferation, thus limiting the number of cells available for adipogenesis. CONCLUSIONS Our study describes an important role of SMYD3 as a newly discovered regulator of adipocyte precursor proliferation during the early steps of adipogenesis.

Abstract
Exercise training and cold exposure both improve systemic metabolism, but the mechanisms are not well-established. We tested the hypothesis that adaptations to inguinal white adipose tissue (iWAT) are critical for these beneficial effects by determining the impact of exercise-trained and cold-exposed iWAT on systemic glucose metabolism and the iWAT proteome and secretome. Transplanting trained iWAT into sedentary mice improved glucose tolerance, while cold-exposed iWAT transplantation showed no such benefit. Compared to training, cold led to more pronounced alterations in the iWAT proteome and secretome, downregulating >2,000 proteins but also boosting iWAT's thermogenic capacity. In contrast, only training increased extracellular space and vesicle transport proteins, and only training upregulated proteins that correlate with favorable fasting glucose, suggesting fundamental changes in trained iWAT that mediate tissue-to-tissue communication. This study defines the unique exercise training- and cold exposure-induced iWAT proteomes, revealing distinct mechanisms for the beneficial effects of these interventions on metabolic health.

Abstract
Inguinal white adipose tissue (iWAT) is essential for the beneficial effects of exercise training on metabolic health. The underlying mechanisms for these effects are not fully understood, and here, we test the hypothesis that exercise training results in a more favorable iWAT structural phenotype. Using biochemical, imaging, and multi-omics analyses, we find that 11 days of wheel running in male mice causes profound iWAT remodeling including decreased extracellular matrix (ECM) deposition and increased vascularization and innervation. We identify adipose stem cells as one of the main contributors to training-induced ECM remodeling, show that the PRDM16 transcriptional complex is necessary for iWAT remodeling and beiging, and discover neuronal growth regulator 1 (NEGR1) as a link between PRDM16 and neuritogenesis. Moreover, we find that training causes a shift from hypertrophic to insulin-sensitive adipocyte subpopulations. Exercise training leads to remarkable adaptations to iWAT structure and cell-type composition that can confer beneficial changes in tissue metabolism.

Abstract
Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance exercise training and sex on its molecular landscape has not been fully established. Utilizing an integrative multi-omics approach with data generated by the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we identified profound sexual dimorphism in the dynamic response of rat scWAT to endurance exercise training. Despite similar cardiorespiratory improvements, only male rats reduced whole-body adiposity, scWAT adipocyte size, and total scWAT triglyceride abundance with training. Multi-omic analyses of adipose tissue integrated with phenotypic measures identified sex-specific training responses including enrichment of mTOR signaling in females, while males displayed enhanced mitochondrial ribosome biogenesis and oxidative metabolism. Overall, this study reinforces our understanding that sex impacts scWAT biology and provides a rich resource to interrogate responses of scWAT to endurance training.

Abstract
Chronic inflammation that affects primarily metabolic organs, such as white adipose tissue (WAT), is considered as a major cause of human obesity-associated co-morbidities. However, the molecular mechanisms initiating this inflammation in WAT are poorly understood. By combining transcriptomics, ChIP-seq and modeling approaches, we studied the global early and late responses to a high-fat diet (HFD) in visceral (vWAT) and subcutaneous (scWAT) AT, the first being more prone to obesity-induced inflammation. HFD rapidly triggers proliferation of adipocyte precursors within vWAT. However, concomitant antiadipogenic signals limit vWAT hyperplastic expansion by interfering with the differentiation of proliferating adipocyte precursors. Conversely, in scWAT, residing beige adipocytes lose their oxidizing properties and allow storage of excessive fatty acids. This phase is followed by tissue hyperplastic growth and increased angiogenic signals, which further enable scWAT expansion without generating inflammation. Our data indicate that scWAT and vWAT differential ability to modulate adipocyte number and differentiation in response to obesogenic stimuli has a crucial impact on the different susceptibility to obesity-related inflammation of these adipose tissue depots.

Abstract
Abstract
The tumor microenvironment is increasingly recognized as a contributor to cancer development and progression since several stromal components, including fibroblasts, interact with cancer cells regulating their behavior and ultimately affecting tumor phenotype. Using primary cultures of human fibroblasts isolated from resected lung cancers we previously demonstrated that co-injection with cancer cells results in increased tumorigenicity and altered expression of ECM related genes in heterotypic tumors. To identify factors involved in the cross-talk between fibroblasts and lung cancer cells, microarray gene expression profiling was performed on 60 fibroblast lines from cancerous and normal lung tissue from primary lung cancer patients, including 25 pairs of normal (NF) and cancer-associated fibroblasts (CAF) from the same patients. Lines were also characterized for presence of the activation marker alpha-SMA and for in vivo pro-tumorigenic activity by co-injection with A549 adenocarcinoma cells. Class comparison analyses identified: (i) Factors highly expressed in cancer-associated fibroblasts (CAF) compared to normal fibroblasts (NF): RHOB, SNAI2, EDIL3, LRRN3, CHN1, CTSC, NOPE and DOCK10; (ii) Genes highly expressed in activated fibroblasts: POSTN, TNFAIP6, CLEC2B and (iii) Genes associated with an in vivo pro-tumorigenic phenotype: CNTN3, ELOVL6, MET, XPO1.
To explore the potential prognostic value of these microenvironment related markers, we selected antibodies against 20 proteins differentially expressed in lung fibroblasts and evaluated their performance in immunohistochemistry on FFPE sections of 74 cases of NSCLC. Selection criteria to prioritize candidates for IHC were based on results from molecular analyses (both microarray hybridization and Real-Time PCR validation) and involvement in biological pathways identified as potentially relevant by Gene Set Enrichment Analysis (GSEA). The frequency of positive cells was evaluated on: cancer cells, cancer-associated fibroblasts (CAF) and fibroblasts in normal tissue adjacent (AF) or distant (NF) from the surgical margin. This in-depth analysis revealed heterogeneous expression of different proteins with factors predominantly expressed by cancer cells (LRRN3) and others by the stromal component (CLEC2B). Among factors expressed by fibroblasts, positivity for NOPE, MET, CTSC and CLEC2B was detected in the majority of cases (60-70%) and they were generally expressed at higher frequency by CAF compared to NF. In univariate Cox models, SNAI2 expression by CAF was shown to correlate with worst overall survival (p=0.0288) and we further identified association of CNTN3 expression by CAF with shorter disease free survival (p=0.0125).These findings strengthen the hypothesis that identification of factors responsible for proficient tumor-stroma cross-talk could be instrumental in innovative strategies for risk assessment.

Abstract
OBJECTIVE To describe the clinical outcomes of histologically confirmed adenocarcinoma in situ (AIS) of the cervix treated with cervical conization. MATERIALS AND METHODS A retrospective chart review of patients with histologically confirmed AIS from July 1998 to February 2011 included 52 patients. The rates of residual disease in subsequent excisions, the clinical recurrence rate, the average disease-free interval, and risk of progression to adenocarcinoma were described. The clinical outcomes of patients treated with cold knife cone (CKC) and loop electrosurgical excisional procedure (LEEP) were compared. RESULTS Fifteen LEEPs and 37 CKC procedures were performed as initial treatment and 26 patients (50%) had positive margins. There was no significant difference in rate of positive margins between LEEP and CKC (40% vs. 54%, respectively. p = 0.55). LEEPs and CKCs resulted in similar volumes of cervical tissue resected (4.98 cm3 vs. 5.04 cm3, p = 0.40). Of patients with positive margins, ten underwent immediate hysterectomy, six underwent a second cone biopsy, seven were managed expectantly, and four were lost to follow up. Residual AIS was found in 47% (eight of 17) of repeat cone biopsy and hysterectomy specimens performed for positive cone margins. Of the 26 patients with negative cone margins, no residual or recurrent disease was found after an average follow-up of 32 months. CONCLUSIONS A positive surgical margin was associated with residual disease in 47% of patients with AIS treated with conization. No patient with negative cone margins had recurrent or progressive disease. Cervical conization with negative margins appears to be a safe treatment option for patients with AIS but requires further investigation. CKC and LEEP were equally efficacious treatments in our study population.

Abstract
Abstract
There is increasing evidence of the central contribution of tumor microenvironment to cancer development and progression. The elucidation of the role of different cellular components to this mechanism might therefore provide novel insights on the transformation process and potentially indicate targets for innovative therapeutic intervention. In particular, it has been shown that fibroblasts isolated from invasive breast lesions can contribute to tumor growth through the CXCR4/SDF1 pathway and that human prostatic carcinoma-associated fibroblasts (CAFs) can drive the progression of initiated non-tumorigenic epithelial cells. Recently a gene-expression signature derived from lung CAFs was shown to have prognostic value in non-small cell lung cancer (NSCLC) patients. To further investigate the contribution of fibroblasts to lung cancer we established primary cultures of CAFs and matched normal fibroblasts (NFs) from resected NSCLC and performed co-injection experiments in nude mice with A549 lung cancer cells. Co-injection of fibroblasts generally resulted in tumors of bigger size and/or increased take rate when cells were injected at low doses. Time-course experiments revealed presence of human cells in the stromal component of xenografts up to one month after injection, indicating possible involvement also in the progression phase. To evaluate the contribution of fibroblasts to extracellular matrix composition of tumors we therefore analyzed by real-time PCR with human specific primers the expression levels of 14 extracellular matrix (ECM) related genes in 63 tumors generated by co-injection of lung cancer cells and fibroblasts (CAFs or NFs). Compared to tumors generated by injection of A549 cells alone, heterotypic tumors displayed strongly increased levels of COL6A3 and MMP2 (p≤0.03), slightly increased levels of SPARC and reduced CTSL and CTSC (p≤0.01) indicating influence of fibroblasts on ECM composition. Tumors generated by co-injections were also more likely to metastasize to the lungs as determined by flow cytometry and real-time PCR (31% vs. 17%; OR=2.56 95% CI 0.6-12.7). Moreover culturing of primary lung cancer cells with CAF conditioned medium (CM) also resulted in similar transcriptional regulations of ECM-related genes and increased levels of MMP2 were detected in tumors derived from injection of CM treated cells. Taken together these data demonstrate that cross-talk between fibroblasts and cancer cells can dictate ECM composition and regulate dissemination of lung cancer and suggest that identification of factors responsible for this cross-talk could be instrumental in devising novel therapeutic strategies.

Abstract
BACKGROUND Ixabepilone is a semisynthetic epothilone B analogue that is active in taxane-resistant cell lines and has shown activity in patients with refractory breast and ovarian cancer. We carried out a phase I trial of ixabepilone plus pegylated liposomal doxorubicin (PLD) in patients with advanced taxane-pretreated ovarian and breast cancer. METHODS Patients with recurrent ovarian or breast carcinoma received PLD every 3 or 4 weeks plus five different dose schemas of ixabepilone in cohorts of three to six patients. RESULTS Thirty patients received a total of 142 treatment cycles of the PLD-ixabepilone combination. The recommended phase II dose and schedule of ixabepilone was 16 mg/m(2) on days 1, 8, and 15 plus PLD 30 mg/m(2) given on day 1, repeated every 4 weeks. Hand-foot syndrome and mucositis were dose limiting when both ixabepilone and PLD were given every 3 or 4 weeks. Objective responses were observed in 3 of 13 patients (23%) with breast cancer and 5 of 17 patients (29%) with ovarian cancer. CONCLUSION Ixabepilone may be safely combined with PLD, but tolerability is highly dependent upon the scheduling of both agents. This combination demonstrated efficacy in patients with breast and ovarian cancer and merits further evaluation in these settings.

Abstract
2570 Background: Ixabepilone (IX) is a semisynthetic epothilone B analog with activity in patients (pts) with taxane refractory cancer. Two phase III clinical trials in breast cancer (BC) and a phase II study in ovarian cancer (OC) have recently been completed. Pegylated liposomal doxorubicin (PLD) is used for the treatment of platinum refractory OC and has activity in patients with metastatic BC. Methods: We have completed enrollment of a phase I study of PLD IV and ixabepilone IV over 3 hours. 18 pts with metastatic cancer (10 BC and 8 OC) with median age 51 were enrolled from 1/13/06 to 12/22/06. A total of 60 cycles has been administered to date. 3 OC patients enrolled at dose level 3 have not yet completed 2 cycles of treatment and are not yet evaluable. Results: Dose limiting toxicities (DLT) based on toxicities experienced during the first 2 cycles is provided in the table below. Adverse events (AE) occurring in any cycle were: Grade 4 AE: neutropenia < 7 days (1 pt). Grade 3 AE: palmar plantar erythrodysesthesia (PPE) (4), mucositis (3), infection (2), fatigue (2), neutropenia (2), thrombocytopenia (2), anemia (1), neuropathy (1), bilirubin (1). Non-hematological grade 2 AEs included: mucositis (4), PPE (3), infection (2), neuropathy (2), rash (3), pain (3), fever (1), myalgias (1), and anorexia (1). Responses so far for 10 BC pts are PR (1) SD (3) PD (6) and for 5 OC pts are PR (1) SD (2) PD (2). Updated results will be presented. Conclusions: Although the recommended phase II dose when given every 3 weeks is 30 mg/m2 for PLD and 32 mg/m2 for IX by our criteria, PPE and mucositis became problematic when treatment was continued beyond 2 cycles. We are therefore exploring a 4 week PLD schedule, evaluating IX given either every 4 weeks (as shown) or weekly (on days 1, 8, and 15). A phase II trial of the combination in platinum refractory OC will be initiated upon completion of the phase I. Supported by N01-CM-62204 [Table: see text] [Table: see text]

Abstract
The adsorption of CO and its reaction with oxygen were investigated using a combination of in situ Fourier transform infrared spectroscopy, step response measurements in a microreactor, (18)O isotopic labeling, and X-ray absorption near edge structure spectroscopy. An as-prepared sample in which Au is present as a surface oxyhydroxy complex does not adsorb CO. On an activated sample in which only metallic Au is detected, 0.18 +/- 0.03 mol CO/(mol Au) are adsorbed on Au at -60 degrees C, which shows an IR band at 2090 cm(-1). When oxygen is present in the gas phase, this species reacts with a turnover rate of 1.4 +/- 0.2 mol CO(mol Au min)(-1), which is close to the steady-state turnover rate. In contrast, there is a very small quantity of adsorbed oxygen on Au. A small IR peak at 1242 cm(-1) appears when an activated sample is exposed to CO. It reacts rapidly with oxygen and is shifted to 1236 cm(-1) if (18)O is used. It is assigned to the possible intermediate hydroxycarbonyl.

Abstract
Changes in a Au/TiO(2) catalyst during the activation process from an as-prepared state, consisting of supported AuO(x)(OH)(4-2x)(-) species, were monitored with X-ray absorption spectroscopy and FTIR spectroscopy, complemented with XPS, microcalorimetry, and TEM characterization. When the catalyst was activated with H(2) pulses at 298 K, there was an induction period when little changes were detected. This was followed by a period of increasing rate of reduction of Au(3+) to Au(0), before the reduction rate decreased until the sample was fully reduced. A similar trend in the activation process was observed if CO pulses at 273 K or a steady flow of CO at about 240 K was used to activate the sample. With both activation procedures, the CO oxidation activity of the catalyst at 195 K increased with the degree of reduction up to 70% reduction, and decreased slightly beyond 80% reduction. The results were consistent with metallic Au being necessary for catalytic activity.

Abstract
OBJECTIVE The aim of this study was to determine whether the risk of ovarian carcinoma was related to latitude or to genetically based patterns of European geographic origin. PATIENTS AND METHODS We studied the countries of origin of European-born grandparents of 168 newly diagnosed patients in two hospitals in New York City, compared with 159 controls from similar neighborhoods. We measured the risk of this cancer associated with having one or more white, non-Jewish grandparents born in North Europe versus none or in South Europe versus none. We also classified geographic origins in other ways to reflect the two main trends in genetic variations between Europeans mapped by Cavalli-Sforza et al. (The History and Geography of Human Genes, Princeton University Press, Princeton, 1994). Unconditional logistic regression was used to control for age, parity, years of use of oral contraception, age at menarche, education, Catholic religion, and area of residence and for numbers of Jewish grandparents, siblings, and first-degree relatives with breast or ovarian cancer. RESULTS Approximately half of the subjects had least one white, non-Jewish grandparent born in Europe. There was no significant effect of ancestral latitude: among women born in the United States the odds ratio (OR) and 95% confidence limits associated with North European ancestry were 0.87 (0.47--1.63) compared with a reference group of women with no such ancestry. The corresponding OR for South Europe was 0.73 (0.39--1.74). Using the genetically based classifications of countries of origin, however, we found significant differences between cases and controls; ancestries from North West Europe and those from countries concentrically near Spain showed lower risks of ovarian carcinoma. CONCLUSIONS The results support the hypothesis that the previously observed effects of latitude must act through environmental effects or through gene-environment interactions. Other variations in risk related to geographic origins are consistent with known patterns of genetic differences, but require confirmation in larger, population-based studies.

Abstract
Patients with HIV have an increased incidence of cervical cancer, necessitating increased surveillance. Infrared spectroscopy (IRS) has the potential of aiding the diagnosis of cervical neoplasia and also of providing clues into its pathogenesis. We studied by IRS cervical scrapings from 22 HIV-infected and 23 control women; 8 of the former and none of the latter had dysplasia. The infrared spectra followed three patterns, designated pattern I (similar to that previously associated with normal cervical samples), pattern II (intermediate between patterns I and III), and pattern III (associated with cervical neoplasia). Compared with HIV-negative controls, HIV-infected women had a higher prevalence of pattern III and a lower prevalence of pattern II; these differences were statistically significant (P = .015 by chi2 analysis). Similar spectroscopic changes were present even when only the cytologically normal samples from HIV-positive and HIV-negative women were analyzed. We speculate that these changes may reflect early structural changes associated with cervical neoplasia that are not detectable cytologically. The infrared spectra in the region 950 to 1,300 cm(-1) could not differentiate cervical samples from HIV-infected and uninfected patients. The potential practical applications of IRS in HIV cervical disease are discussed.

Abstract
PURPOSE To evaluate the long-term control of disease and cure rate, complications, second malignancy, and survival of early-stage endometrial cancer patients treated with surgery, high dose-rate brachytherapy, and external beam radiation therapy. METHODS AND MATERIALS From 1969 through 1979, 300 patients with clinically staged Stage I-II endometrial cancer underwent total abdominal hysterectomy and bilateral salpingo-oopherectomy, followed by high dose-rate intravaginal radiation, 7 Gy x 3 to 0.5 cm from the mucosal surface, using a remote afterloading technique. External beam radiation therapy, 40 Gy to midplane in 4 weeks, was delivered to high risk patients through AP/PA and lateral fields. RESULTS The patients were followed for 5-24 years (median 12). The actuarial progression-free survival rate was 96.6%. Post-treatment grade 1-2 actuarial complication rate was 9.5%, including cystitis (4.5%), vaginal stenosis (2.5%), proctitis (1.5%), vaginal necrosis (0.5%), and partial bowel obstruction (0.5%). Neither grade 3-4 complications nor additional late complications were observed in any of our patients. Relapse rate was only 3.7%, of which 45.5% were local, 45.5% were distant, and 9% were mixed. All the patients with relapse were postmenopausal, age range of 58-77 years, with tumor grade 2-3 in 64%. Second primary cancer rate was 12.8% (mostly breast and colon). Factors that were associated with improved prognosis were young age, premenopausal, low grade, no extrauterine disease, and a histology of adenocarcinoma (adenocarcinoma with squamous metaplasia). CONCLUSION High dose rate intravaginal radiation therapy combined with surgery and external beam radiation therapy achieved a high cure rate small number of minor complications. No long-term treatment-related complications were noted in any of the patients. This treatment combination may be safely applied to patients with early stage endometrial cancer.

Abstract
The contributions of estrogen replacement therapy, smoking, and other risk factors to the development of advanced-stage (2-4) endometrial cancer were evaluated in a case-control study of women 40-69 years old from upstate New York. Eighty-four cases and 168 matched community controls were interviewed in person about estrogen exposure and other risk factors. Despite a statistically significant increase in risk with longer use of estrogen pills (P less than 0.05), estrogen exposure actually contributed little to the overall risk of advanced-stage endometrial cancer. Other physical conditions (increased weight, lower parity, diabetes) and socioeconomic factors (education, access to medical services) largely accounted for advanced-stage disease. The evidence in this study does not support the hypothesis that women who smoke have a lower risk than nonsmokers of developing advanced-stage endometrial cancer.

Abstract
The effect of cigarette smoking on the risk of early-stage endometrial cancer was evaluated in a population-based case-control study of women aged 40 to 69 years from upstate New York. Two hundred women with early-stage endometrial cancer diagnosed between 1979 and 1981, and 200 matched community controls were interviewed in person and asked about smoking habits and other risk factors. Statistical analysis revealed a significant decline in relative risk with increased smoking (P less than 0.05). This effect strongly modified the well-known increase in risk with body weight. Among smokers risk did not increase with body weight, whereas among nonsmokers risk increased rapidly with body weight, especially among nonsmokers in whom the peripheral conversion of androgens was the primary source of serum estrogen. Despite this apparent reduced risk for endometrial cancer, smoking remains a major health hazard for women as well as men.

Abstract
As part of our efforts to define subpopulations at increased risk for gynecologic malignancies, sera from 145 women were obtained prior to diagnosis and analyzed for antibody to asialo ganglio-N-tetraosylceramide. This neutral glycolipid is present on the surface of thymocytes and natural killer cells, and asialo ganglio-N-tetraosylceramide antibody has been shown in animals to block natural killer cell activity and promote tumor cell proliferation. With the use of an enzyme-linked immunosorbent assay and with a value of 2 SD above the mean for healthy women designated as the boundary for a positive response, antibody to asialo ganglio-N-tetraosylceramide was detected in only one of 30 (3%) healthy women, none of 16 pregnant women, none of 18 women with benign masses, and two of 24 (8%) women with microbial infections. All of the above samples that contained antibodies were barely over the 2 SD limit. In marked contrast, 19 of 35 (54%) women with gynecologic malignancies had asialo ganglio-N-tetraosylceramide antibodies, with positive values ranging to greater than 10 SD above the control mean. Asialo ganglio-N-tetraosylceramide antibody was found in six of eight (75%) patients with cervical cancer, five of eight (63%) with endometrial cancer, and seven of 15 (47%) with ovarian cancer. Of the eight patients with Stage I gynecologic cancer at any site, five (62%) had asialo ganglio-N-tetraosylceramide antibodies. Four of 22 (18%) women with Hodgkin's disease also had antibodies, with values just exceeding 2 SD above control levels. The presence of these antibodies may contribute to an impaired immune surveillance system in these women and so increase their susceptibility to malignancy.

Abstract
In contrast to other malignancies, circulating immune complexes (CICS) are usually not detected by conventional assays in the sera of ovarian cancer patients. However, a polyethylene glycol (PEG) precipitation assay has been reported to detect putative CICS in ovarian cancer. To determine if CICS were indeed present, we analyzed sera from 12 women with ovarian cancer. All were negative for CICS by the Raji cell assay; 5 (42%) were positive by the PEG assay. However, the PEG precipitate did not possess characteristics of immune complexes. IgG in sera or in the precipitate sedimented in sucrose gradients solely at the same rate as 7S monomeric IgG. In addition, the precipitates were not able to activate the complement system and the four IgG subclasses were present in the same relative concentration as that found in normal serum. The results suggest that it is probably a misnomer to label the material detected in ovarian cancer sera by the PEG precipitation assay as CICS. Instead a non-immune interaction of IgG with other components, possibly membrane fragments, is probably being measured.

Abstract
A population-based case-control study was conducted with 403 white, ovarian cancer patients, 20-79 years of age, who were diagnosed from October 1977 through February 1980 in 11 New York State counties. The study also included 806 controls who were matched to the cases by age, race, and county of residence. The contraceptive and reproductive patterns observed in this study suggest that infertility plays an important role in determining the relationship between reduced parity and gravidity and increased ovarian cancer risk. Ovarian cancer patients were less likely than controls to have ever used nonpermanent birth control methods (relative risk = 0.63, 95% confidence interval = 0.45-0.89), and they tended to practice contraception less often. A direct graded-response relationship was observed between ovarian cancer risk and the number of contraceptive-free years of marriage (chi 2 Linear trend = 5.911, p = 0.02). An inverse graded-response relationship was observed between gravidity and risk. This relationship persisted even after contraception was taken into account (chi 2 Linear trend = 13.002, p = 0.0003). Ovarian cancer risk was not found to be associated with an excess in reported fetal loss.
