Question: Context: Emerging evidence suggests that the in utero environment is not sterile as once presumed. Work in the mouse demonstrated transmission of commensal bacteria from mother to fetus during gestation, though it is unclear what modulates this process. We have previously shown in the nonhuman primate that, independent of obesity, a maternal high-fat diet during gestation and lactation persistently shapes the juvenile gut microbiome. We therefore sought to interrogate in a population-based human longitudinal cohort whether a maternal high-fat diet similarly alters the neonatal and infant gut microbiome in early life.', 'A representative cohort was prospectively enrolled either in the early third trimester or intrapartum (n=163), with a subset consented to longitudinal sampling through the postpartum interval (n=81). Multiple body site samples, including stool and meconium, were collected from neonates at delivery and by 6weeks of age. A rapid dietary questionnaire was administered to estimate intake of fat, added sugars, and fiber over the past month (National Health and Examination Survey). DNA was extracted from each infant meconium/stool sample (MoBio) and subjected to 16S rRNA gene sequencing and analysis.', "On average, the maternal dietary intake of fat ranged from 14.0 to 55.2%, with an average intake of 33.1% (=6.1%). Mothers whose diets significantly differed from the mean (1 standard deviation) were separated into two distinct groups, a control group (n=13, =24.4%) and a high-fat group (n=13, =43.1%). Principal coordinate analysis revealed that the microbiome of the neonatal stool at birth (meconium) clustered differently by virtue of maternal gestational diet (PERMANOVA p=0.001). LEfSe feature selection identified several taxa that discriminated the groups, with a notable relative depletion of Bacteroides in the neonates exposed to a maternal high-fat gestational diet (Student's t-test, p<0.05) that persisted to 6weeks of age.
Answer: Similar to the primate, independent of maternal body mass index, a maternal high-fat diet is associated with distinct changes in the neonatal gut microbiome at birth which persist through 4-6 weeks of age. Our findings underscore the importance of counseling pregnant mothers on macronutrient consumption during pregnancy and lactation.

Answer: Does the early infant gut microbiome vary in association with a maternal high-fat diet?

Question: Context: Mutations of the caspase-activating recruitment domain 15 (CARD15) gene on chromosome 16 are associated with chronic inflammatory granulomatous bowel disease (Crohn's disease). Sarcoidosis is a systemic granulomatous disease with unknown etiology, which shares histological features with Crohn's disease.", 'To evaluate whether ethnic Danes with sarcoidosis have an increased frequency of CARD15 mutations compared to healthy control subjects.', 'Genotyping for CARD15 mutations R702W, G908R, and L1007fsinsC, also designated single nucleotide polymorphism (SNP) SNP8, SNP12 and SNP13, respectively, were performed by capillary electrophoresis single-strand confirmation polymorphism in 53 patients with histologically verified sarcoidosis and in 103 healthy controls.', 'The frequencies of CARD15 mutations in sarcoidosis patients were: SNP8, 4/106 chromosomes (3.8%); SNP12, 2/106 chromosomes (1.9%); SNP13, 2/106 chromosomes (1.9%); SNP8+SNP12+SNP13, 8/106 chromosomes (7.6%). All 8 patients were heterozygous. The frequencies in controls were: SNP8, 9/206 chromosomes (4.4%); SNP12, 2/206 chromosomes (1.0%); SNP13, 4/206 chromosomes (1.9%); SNP8+SNP12+SNP13, 15/206 chromosomes (7.3%). All controls were heterozygous. The differences were not statistically significant (p>0.05). Furthermore, the course of disease was not significantly different in the 8 patients with CARD15 mutations and the 45 patients without mutations.
Answer: The frequency of CARD15 mutations is not increased in ethnic Danish patients with sarcoidosis, and heterozygosity for such mutations apparently has no influence on the course of disease.

Answer: Are cARD15 single nucleotide polymorphisms 8 , 12 and 13 increased in ethnic Danes with sarcoidosis?

Question: Context: Microbiota has been suggested in promoting chronic inflammation in human tissues which, in turn, promotes tumor development. This study tests a hypothesis that high-risk human papillomavirus (HR-HPV) infection may correlate with proinflammatory Stat3 signaling activities and IL-17 levels in breast cancer (BC) patients.', 'This study examined HPV infection by GenChip technology, constitutively active Stat3 (p-Stat3) and IL-17 levels by immunohistochemistry (IHC) using specific antibodies in 379 BC patients, together with 245 paired adjacent breast adenosis (ABA) tissues and 100 unrelated breast adenosis (BA) tissues.', "We obtained four major findings: (1) HR-HPV16/18 infections existed in 10.5% (34/325) of BC issues, higher than control BA tissues (4%, 4/100, P = 0.047). (2) Using IHC methodology, BC tissues showed more overactive p-Stat3 (2+/3+, 38.5%, 146/379) than ABA tissues (27.3%, 67/245, P < 0.001); similarly, BC also had more tissues overexpressing IL-17 (2+/3+, 61.5%, 233/379) than ABA tissues (51.8%, 127/245, P < 0.001). (3) High levels (2+/3+) of both active p-Stat3 and IL-17 correlated with poor differentiation and lymph nodal metastasis in BC (both with P < 0.05), but not with patients' prognosis. (4) HR-HPV infections correlated with both active p-Stat3 (P = 0.018) and its downstream IL-17 levels (P = 0.021) in BC tissues.
Answer: There may be a possible tri-lateral relationship among HPV infection, constitutive Stat3 activity and IL-17 level, whose collaborations could orchestrate a proinflammatory microenvironment in breast tissues by which promote carcinogenesis and/or facilitate progression of breast cancer.

Answer:
Does human papillomavirus infection correlate with inflammatory Stat3 signaling activity and IL-17 expression in patients with breast cancer?
