The enzymatic catalytic capacity of complex I was intact across all temperatures and accordingly the decreased CI-OXPHOS is unlikely to be caused directly by hyperthermic denaturation/inactivation of complex I. Despite the reduction in CI-OXPHOS, maximal OXPHOS capacity was maintained in all species, through oxidation of alternative substrates - proline, succinate and, particularly, glycerol-3-phosphate - suggesting important mitochondrial flexibility at temperatures exceeding the organismal heat limit. Interestingly, this failure of CI-OXPHOS and compensatory oxidation of alternative substrates occurred at temperatures that correlated with species heat tolerance, such that heat-tolerant species could defend 'normal' mitochondrial function at higher temperatures than sensitive species. Future studies should investigate why CI-OXPHOS is perturbed and how this potentially affects ATP production rates.
Chronic inflammation is a well-established mechanism of ovarian carcinogenesis; however, the specific immunogenic processes influencing ovarian tumor development remain unclear. click here In a case-control study nested within the Nurses' Health Study (NHS) and the NHSII, we examined the association between six inflammatory chemokines and cytokines [B-cell activating factor (BAFF), C-X-C motif chemokine ligand 13 (CXCL13), IL8, soluble(s)IL2-receptor-α(Rα), sIL6Rα] and epithelial ovarian cancer risk.

Among 299 epithelial ovarian cancer cases and 334 matched controls, six inflammatory biomarkers were measured in plasma collected 1-24 years before diagnosis or index date using two custom multiplex Luminex panels. ORs and 95% confidence intervals (CI) were estimated for the association between each biomarker and risk using multivariable conditional logistic regression with adjustment for relevant confounders. We additionally assessed heterogeneity in the risk associations by histotype [high-grade serous carcinoma (HGSC) vs. non-HGSC], body mass index, smoking status, menopausal status, and aspirin use.

Women with the highest versus lowest quartile (Q) levels of CXCL13 had a 72% increased ovarian cancer risk (OR = 1.72; 95% CI = 1.04-2.83;

= 0.007). The positive association with CXCL13 was stronger in magnitude for non-HGSC, overweight or obese women, and postmenopausal women, although only menopausal status demonstrated statistically significant heterogeneity (

= 0.04). The remaining biomarkers were not associated with risk.

This first evidence that prediagnostic CXCL13, a B-cell chemoattractant, is associated with an increased risk of epithelial ovarian cancer expands current understanding of the role of inflammation in ovarian carcinogenesis.

CXCL13 may represent a novel biomarker for ovarian cancer.

Most studies examining the associations of sugary drink consumption on colorectal cancer risk have been conducted in Western populations.

This study consisted of 74,070 participants in the Japan Public Health Center-based Prospective Study who completed a food frequency questionnaire (1995-1999). The participants were followed until December 2013 to investigate the associations between sugary drink consumption and colorectal cancer risk using Cox proportional hazards regression models.

Among the 74,070 participants, mean age was 56.5 years at baseline, with a mean body mass index (BMI) of 23.5 and a mean daily consumption of 286 mL/day for men and 145 mL/day for women. During a follow-up of 15 years, 1,648 colorectal cancer cases were identified. No overall greater risk of colorectal cancer was observed among men [multivariable HR = 0.84; 95% confidence of interval (CI), 0.70-1.02; ≥254 mL/day vs. nonconsumers] and women (HR = 1.20; 95% CI, 0.96-1.50, ≥134 mL/day vs. nonconsumers). Sugary drink consumption was associated with colon cancer among women (HR = 1.36; 95% CI, 1.03-1.78, ≥134 mL/day vs. nonconsumers). HRs for proximal colon cancer among women who consumed sugary drinks, as compared with nonconsumers, were 1.47 (95% CI, 1.03-2.10) for sugary drink consumption less than 134 mL/day, and 1.45 (95% CI, 1.01-2.09) for at least 134 mL/day.

In this large prospective cohort of Japanese with a moderate sugary drink consumption level and low prevalence of obesity, we observed a 36% increased risk of colon cancer in women.

In recent decades, Cesarean section (C-section) rates have increased. C-section is hypothesized to negatively impact the developing immune system by altering activation of the hypothalamic-pituitary-adrenal axis and the infant microbiome, among other mechanisms, thereby potentially modulating childhood cancer risk.

Using linked birth and cancer registry data from Minnesota (1976-2014), we included individuals ages 0-14 at diagnosis with one of 19 cancers. Cases and controls were frequency matched by birth year. We used logistic regression to estimate ORs and 95% confidence intervals (95% CI) as the measure of association between C-section and cancer. We assessed sex-C-section interactions for each cancer and conducted stratified analyses in acute lymphoblastic leukemia (ALL) for birth year, age at diagnosis, and maternal race.

There were 3,166 cases and 20,589 controls. One third (
= 1,174) of controls born during 2004-2014 were delivered via C-section compared with 42.2% of cases (
= 285). C-section was associated with ALL (
= 819; OR 1.20; 95% CI 1.01-1.43) and hepatoblastoma (
= 50; OR 1.89; 95% CI 1.03-3.48), particularly among females (ALL OR 1.34; 95% CI 1.04-1.72; hepatoblastoma OR 3.87; 95% CI 1.30-11.57). The risk of ALL was highest during 2005-2014 (OR 1.62; 95% CI 1.11-2.34) and among children ages 1-5 years (OR 1.28; 95% CI 1.02-1.61).

C-section was associated with an increased risk of ALL and hepatoblastoma.

These associations require investigation to determine causality and rule out confounding by indication or reverse causality. The mechanisms underlying these associations may depend on neonatal immune system processes altered during C-section deliveries.

While some risk factors for breast cancer have been confirmed, less is known about the role of early biological and social risk factors for breast cancer in adult life.

In a prospective follow-up in the Northern Finland Birth Cohort 1966 consisting of 5,308 women, 120 breast cancers were reported via national registers by the end of 2018. Early risk factors were examined with univariate and multivariate analyses using Cox regression analysis. The main results are reported with HRs and their 95% confidence intervals (CI).

In the multivariate-adjusted models, women whose mothers lived in urban areas (HR, 1.68; 95% CI, 1.13-2.51) during pregnancy, were low educated (HR, 2.40; 95% CI, 1.30-4.45), and had been diagnosed with breast cancer (HR, 1.97; 95% CI, 1.09-3.58) had a higher risk for breast cancer in adult life. Lower BMI at the age of 14 associated nonsignificantly with the risk of breast cancer (Mann-Whitney
test,
= 0.087). No association between birth size and breast cancer risk in adult life was found.

Early-life residence and socioeconomic conditions may have an impact on developing breast cancer in women in adult life. All breast cancer cases of this study were relatively young, and most of them are assumed to be premenopausal.

This study is one of a few prospective birth cohort studies to examine early-life socioeconomic factors and breast cancer risk in adult life. This study is limited due to small number of cases.

Atypical glandular cells (AGC) are rare abnormalities found on cervical cytology associated with a range of lesions of the female reproductive system. We compared the risk of cervical and other gynecologic cancers following AGC on cervical cytology with the risk following squamous cell abnormalities of comparable severity.

We used data from the Dutch Pathology Archive (PALGA) from 2000 to 2015 to categorize cervical cytology tests into groups based on most severe cytologic abnormality and correlated follow-up advice (normal cytology and "no follow-up" advice, squamous-cell-based, AGC-based, and combined AGC/squamous-cell based each with either repeat testing or referral advice). Cancer data were linked from the Netherlands Cancer Registry. Cox proportional hazard models were calculated stratified by age [younger (<50 years) and older (50+ years)], adjusted for number of previous primary cytology tests.

8,537,385 cytology smears and 9,061 cancers were included. When repeat cytology testing was advised, HRs of cervical cancer (younger women HR, 6.91; 95% CI, 5.48-8.71; older women HR, 3.98; 95% CI, 2.38-6.66) or other gynecologic cancer diagnosis in younger women (HR, 2.82; 95% CI, 1.39-5.74) were significantly higher after an AGC-based abnormality compared with squamous-based abnormalities. Hazards were also significantly higher for "referral" advice cytology, except for cervical cancer among older women (HR, 0.88; 95% CI, 0.63-1.21).

AGC indicates an increased risk of gynecologic cancer compared with squamous-based abnormalities of comparable severity.

Gynecologists should be alert for cervical and endometrial cancers when examining women referred following AGC.

Alterations in the intestinal microbiota are linked with a wide range of autoimmune and inflammatory conditions, including inflammatory bowel diseases (IBD), where pathobionts penetrate the intestinal barrier and promote inflammatory reactions. In patients with IBD, the ability of intestinal macrophages to efficiently clear invading pathogens is compromised resulting in increased bacterial translocation and excessive immune reactions. Here, we investigated how an IBD-associated loss-of-function variant in the protein tyrosine phosphatase non-receptor type 2 (
) gene, or loss of PTPN2 expression affected the ability of macrophages to respond to invading bacteria.

IBD patient-derived macrophages with wild-type (WT)
or carrying the IBD-associated
SNP, peritoneal macrophages from WT and constitutive PTPN2-knockout mice, as well as mice specifically lacking
in macrophages were infected with non-invasive K12
, the human adherent-invasive
(AIEC)
, or a novel mouse AIEC (
AIEC) strain.

Loss of PTPN2 severely compromises the ability of macrophages to clear invading bacteria. Specifically, loss of functional PTPN2 promoted pathobiont invasion/uptake into macrophages and intracellular survival/proliferation by three distinct mechanisms Increased bacterial uptake was mediated by enhanced expression of carcinoembryonic antigen cellular adhesion molecule (CEACAM)1 and CEACAM6 in
-deficient cells, while reduced bacterial clearance resulted from defects in autophagy coupled with compromised lysosomal acidification. In vivo, mice lacking
in macrophages were more susceptible to
AIEC infection and
AIEC-induced disease.

Our findings reveal a tripartite regulatory mechanism by which PTPN2 preserves macrophage antibacterial function, thus crucially contributing to host defence against invading bacteria.
