S Khalkhali, N Mojgani
This study was designed to isolate and identify the potential probionts present in 32 healthy mothers' breast milk. Microbial culture media and 16SrRNA sequencing were used to isolate and identify the bacteria and all isolates were analyzed for their antagonistic potential, resistance to acidic pH, bile salts and survival under simulated gastric and intestinal conditions. The colonization potential was further assessed based on adherence to human enterocyte-like Caco-2 cell lines. The breast milk samples harbored significant numbers of Gram positive and catalase negative (85%) bacteria...

Human milk is a complex fluid that has developed to satisfy the nutritional requirements of infants. In addition to proteins, lipids, carbohydrates and other biologically active components, breast milk contains a diverse microbiome that is presumed to colonize the infant gastrointestinal tract and a heterogeneous population of cells with unclear physiological roles and health implications. Noteworthy cellular components of breast milk include progenitor/stem cells. This review summarizes the current state of knowledge of breast milk cells, including leukocytes, epithelial cells, stem cells and potentially probiotic bacteria...

Nucleobindin 2 has been reported that its high expression is associated with poor outcome and promotes cell migration and lymph node metastasis in breast cancer, colon cancer, and prostate cancer. However, we aimed to investigate the nucleobindin 2 expression in gastric cancer tissues and adjacent non-tumor tissues and its potential relevance to clinicopathological factors and prognosis using immunohistochemical analysis. In our study, nucleobindin 2 level in gastric cancer tissues was higher than in non-tumor tissues...

Colorectal adenocarcinoma (CRC) is a common tumor with high mortality rates. Interestingly, CRC was found to be colonized by the oral anaerobic bacteria Fusobacterium nucleatum, which accelerates tumor progression and enables immune evasion. The CRC-specific colonization by fusobacteria is mediated through the recognition of tumor displayed Gal-GalNAc moieties by the fusobacterial Fap2 Gal-GalNAc lectin. Here, we show high Gal-GalNAc levels in additional adenocarcinomas including those found in the stomach, prostate, ovary, colon, uterus, pancreas, breast, lung, and esophagus...

The progressive building of the infants' gut microbiota is pivotal for educating their immune system. Human breast milk is among the first sources of microbes for the assembly of the infant's microbiota, but research struggles to give a demonstration for the origin of bacteria in milk. Aiming at contributing to the knowledge on assembly of the mother's milk and infant's microbiome, here we characterized the oral, gut and milk ecosystems in a homogeneous cohort of 36 healthy mother-infants pairs, by 16S rRNA next-generation sequencing...

Persistent activation of IL-6/STAT3 signaling pathway has been frequently detected in human cancer including breast cancer, colon cancer, and multiple myeloma. IL-6/STAT3 can be a promising target for cancer prevent and treatment. However, few STAT3 inhibitors with high efficiency, specificity and safety is available for present clinical cancer therapy. Evista (Raloxifene·HCl) is known as selective estrogen receptor modulator which has been used for the prevention and treatment of osteoporosis and was approved for reducing the risk of invasive breast cancer...

Leptomeningeal carcinomatosis is a rare but serious complication of solid tumors such as melanoma, breast and lung cancer, as well as gastrointestinal carcinomas. Its clinical manifestation is highly variable, presenting as radicular pain with or without neurological deficits, as well as with headaches and hallucinatory irritation symptoms. Leptomeningeal carcinomatosis is often misdiagnosed, which delays treatment. Here we report a rare case of a patient with BRAF-mutated microsatellite stable colon carcinoma with lymphatic and skeletal metastases, who developed neurological symptoms one month after the initial diagnosis of malignancy...

BACKGROUND: The gut microbiota of breast-fed and formula-fed infants differ significantly, as do the risks for allergies, gut dysfunction, and upper respiratory tract infections. The connections between breast milk, various formulas, and the profiles of gut bacteria to these childhood illnesses, as well as the mechanisms underlying the effects, are not well understood. METHODS: We investigated distal colon microbiota by 16S RNA amplicon sequencing, morphology by histomorphometry, immune response by cytokine expression, and tryptophan metabolism in a pig model in which piglets were sow-fed, or fed soy or dairy milk-based formula from postnatal day (PND) 2 to 21...

This study was aimed at investigating the clinicopathological characteristics of tubal metastases originating from primary endometrial, cervical, and nongynecological malignancies. We performed a 4-year retrospective study in which fallopian tube tissues obtained from 60 patients with tubal metastases were examined. In addition, we compared the number of tubal metastasis cases detected during periods of representative or whole tubal sampling. Twenty-three and 37 tubal metastases were found in cases examined after representative and whole tubal sampling techniques, respectively...

The decreasing cost of genomic technologies has enabled the molecular characterization of large-scale clinical disease samples and of molecular changes upon drug treatment in various disease models. Exploring methods to relate diseases to potentially efficacious drugs through various molecular features is critically important in the discovery of new therapeutics. Here we show that the potency of a drug to reverse cancer-associated gene expression changes positively correlates with that drug's efficacy in preclinical models of breast, liver and colon cancers...

REVIEW
Kristin A Kwakwa, Julie A Sterling
Tumor-induced bone disease is common among patients with advanced solid cancers, especially those with breast, prostate, and lung malignancies. The tendency of these cancers to metastasize to bone and induce bone destruction is, in part, due to alterations in integrin expression and signaling. Substantial evidence from preclinical studies shows that increased expression of integrin αvβ3 in tumor cells promotes the metastatic and bone-invasive phenotype. Integrin αvβ3 mediates cell adhesion to several extracellular matrix proteins in the bone microenvironment which is necessary for tumor cell colonization as well as the transmission of mechanical signals for tumor progression...

OBJECTIVES: Circulating 25-hydroxyvitamin D (25-OHD) is associated with improved cancer prognosis in some studies, yet it may be a surrogate marker for physical activity. We investigated the associations of leisure-time physical activity (LTPA) with circulating 25-OHD levels in cancer survivors, and determined whether associations differ by indoor and outdoor activity. DESIGN: Cross-sectional study. SETTING: The US National Health and Nutrition Examination Survey (NHANES)...

Several recent studies have highlighted an additional unexpected localization and site of action for Cathepsin L (Cat L) protease within the nucleus in breast, colon and prostate cancer, however, its role in the nucleus was unclear. It was proposed to mediate proteolytic processing of the transcription factor CCAAT-displacement protein/cut homeobox transcription factor (Cux1) from the full-length p200 isoform to generate the p110 and p90 isoforms, of which the p110 isoform was shown to act as a cell cycle regulator to accelerate entry into the S phase...

Expression of the neonatal splice variant of the voltage-gated sodium channel α-subunit (VGSC) subtype Nav1.5 (nNav1.5), encoded by the gene SCN5A, was shown earlier to be upregulated in human breast cancer (BCa), both in vitro and in vivo. Channel activity promoted BCa invasion of Matrigel(®)in vitro and metastasis in vivo. Consequently, expression of nNav1.5 has been proposed as a functional biomarker of BCa cells with metastatic potential. Here, we have determined immunohistochemically both nNav1.5 and total VGSC (tVGSC) protein expression in a range of adult human tissues...

Small, noncoding RNAs are short untranslated RNA molecules, some of which have been associated with cancer development. Recently we showed that a class of small RNAs generated during the maturation process of tRNAs (tRNA-derived small RNAs, hereafter "tsRNAs") is dysregulated in cancer. Specifically, we uncovered tsRNA signatures in chronic lymphocytic leukemia and lung cancer and demonstrated that the ts-4521/3676 cluster (now called "ts-101" and "ts-53," respectively), ts-46, and ts-47 are down-regulated in these malignancies...

BACKGROUND: Many teenagers are insufficiently active despite the health benefits of physical activity (PA). There is strong evidence to show that inactivity and low fitness levels increase the risk of non-communicable diseases such as coronary heart disease (CHD), type 2 diabetes and breast and colon cancers (Lee et al. Lancet 380:219-29, 2012). A major barrier facing adolescents is accessibility (e.g. cost and lack of local facilities). The ACTIVE project aims to tackle this barrier through a multi-faceted intervention, giving teenagers vouchers to spend on activities of their choice and empowering young people to improve their fitness and PA levels...
