A Clustering Study of Sociodemographic Data, Dietary Patterns, and Gut Microbiota in Healthy and Breast Cancer Women Participating in the MICROMA Study. Mol Nutr Food Res 2024:e2400253.

Abstract
SCOPE This work is part of the clinical study NCT03885648 registered in ClinicalTrials.gov, aimed at studying the relationship among breast cancer, microbiota, and exposure to environmental pollutants. As a first step, we characterized and evaluated risk factors of the participants. METHODS AND RESULTS A case-control study was designed with breast cancer (cases, n = 122) and healthy women (controls, n = 56) recruited in two hospitals of Andalusia (Southern Spain). Participants answered questionnaires of Mediterranean diet adherence and food frequency. Data were collected from medical histories and microbiota was analyzed on stool samples. Most cases (78.2%) were diagnosed as stages I and II. Cases had higher age, body mass index (BMI), glucose, cholesterol, and potassium values than controls. Cases exhibited higher adherence to the Mediterranean diet and their food consumption was closer to that dietary pattern. A hierarchical cluster analysis revealed that the Bacillota/Bacteroidota ratio was the most relevant variable in women with breast cancer, which was higher in this group compared with controls. CONCLUSION Although cases exhibited higher adherence to the Mediterranean diet compared with controls, they presented features and microbiota alterations typical of the metabolic syndrome, probably due to their higher BMI and reflecting changes in their lifestyle around the time of diagnosis.

Abstract
AIM: Cancer breast is one of the most common cancer in women leading to death; that is why we are in urgent need to develop new modalities of treatment. Mesenchymal stem cells (MSCs) have an anti-inflammatory effect due to capability to regenerate the damaged tissues.
METHODS: MCF7 breast cancer cells were divided into two groups; group 1: untreated cancer cells, group 2: cancer cell cocultured with MSCs; after 24 incubation the cells from the two groups were collected to assess cell proliferation, Interleukin-6 (IL-6) levels and genes expression of Nuclear factor-kappa B (NF-KB), FOXO, and LncRNA AF085935.
RESULTS: Statistically significant decrease in cancer cell proliferation and all other studied parameters in cancer cells after coculture with MSCs.
CONCLUSION: Breast carcinoma once initiated; it runs in a vicious circle due to stimulation of FOXO/LncRNA AF085935 axis by the inflammatory mediators released from cancer environment. FOXO/LncRNA AF085935 induces cancer proliferation and survival; furthermore, FOXO once induced, it produces further induction of inflammatory cytokines IL-6 and NF-KB and so on, MSCs due to its anti-inflammatory role could break this circle and thus inhibit cancer cell proliferation.

Abstract
Abstract
HCV is the most commonly occurring hepatic infection worldwide. Chronic HCV infection usually complicated with cirrhosis and even HCC with significant morbidity and mortality. The aim of this study to clarify the molecular mechanism by which HCV can induce HCC and identify a new diagnostic marker for early detection of HCC. Methods: 180 participating subject were divided in to three groups. Group 1: 60 healthy individuals (controls). Group 2: 60 HCV infected patients. Group 3: 60 HCV patients developed HCC. Serum IGF, FOXO and LncRNA AF085935 were evaluated. Results: Serum IGF was significantly elevated in HCV and HCC patients, while FOXO and LncRNA AF085935 were significantly up regulated in HCC. IGF significantly correlated with and LncRNA AF085935. Conclusion: HCV can induce IGF with subsequent induction of LncRNA AF085935 and FOXO.
Key word: HCV, HCC, IGF, FOXO and LncRNA AF085935.
