All microorganisms like bacteria, viruses and fungi that reside within a host environment are considered microbiome. The number of bacteria almost equal human cells, however, the genome these may be 100 times larger than genome. Every aspect physiology health can influenced by microbiome living in various parts our body. Any imbalance composition or function is seen as dysbiosis.

Intestinal Dysbiosis: Microbial Imbalance Impacts on Colorectal Cancer Initiation, Progression and Disease Mitigation

Biomedicines, Journal Year: 2024, Volume and Issue: 12(4), P. 740 - 740

Published: March 26, 2024

The human gastrointestinal tract houses a diverse range of microbial species that play an integral part in many biological functions. Several preclinical studies using germ-free mice models have demonstrated the gut microbiome profoundly influences carcinogenesis and progression. Colorectal cancer appears to be associated with dysbiosis involving certain bacterial species, including F. nucleatum, pks+ E. coli, B. fragilis, virome commensals also disrupted patients. A toward these pro-carcinogenic increases significantly CRC patients, reduced numbers preventative Clostridium butyicum, Roseburia, Bifidobacterium evident.

The intricate relationship between anticancer drugs and the gut microbiome influences cancer treatment outcomes. This review paper focuses on role of integrity in enhancing efficacy safety drug therapy, emphasizing pharmacokinetic interactions microbiota. It explores how disruptions to composition, or dysbiosis, can alter metabolism, immune responses, side effects. By examining mechanisms disruption caused by drugs, this highlights specific case studies like cyclophosphamide, 5-fluorouracil, irinotecan, their impact microbial diversity clinical also discusses microbiome-targeted strategies, including prebiotics, probiotics, postbiotics, fecal microbiota transplantation (FMT), as promising interventions enhance treatment. Furthermore, potential profiling personalizing therapy integrating these into practice is explored. Finally, proposes future research directions, developing novel biomarkers a deeper comprehension drug-microbiome interactions, respond current gaps knowledge improve patient outcomes care.

Gut microbiota influences the efficiency of immune checkpoint inhibitors by modulating the immune system (Review)

Oncology Letters, Journal Year: 2024, Volume and Issue: 27(2)

Published: Jan. 5, 2024

Immune checkpoint inhibitors (ICIs) are commonly utilized in tumor treatment. However, they still have limitations, including insufficient effectiveness and unavoidable adverse events. It has been demonstrated that gut microbiota can influence the of ICIs, although precise mechanism remains unclear. Gut plays a crucial role formation development immune system. their associated metabolites play regulatory balance.

Role of Gut Microbial Metabolites in the Pathogenesis of Primary Liver Cancers

Nutrients, Journal Year: 2024, Volume and Issue: 16(14), P. 2372 - 2372

Published: July 22, 2024

Hepatobiliary malignancies, which include hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), are the sixth most common cancers third leading cause of cancer-related death worldwide. Hepatic carcinogenesis is highly stimulated by chronic inflammation, defined as fibrosis deposition, an aberrant imbalance between liver necrosis nodular regeneration. In this context, gut-liver axis gut microbiota have demonstrated a critical role in pathogenesis HCC, dysbiosis altered intestinal permeability promote bacterial translocation, to inflammation tumorigenesis through several pathways. A few data exist on or bacteria resident biliary tract CCA, some microbial metabolites, such choline bile acids, seem show association. review, we analyze impact its metabolites HCC CCA development biomarker hepatobiliary cancer risk response during anti-tumor therapy.

Histone Acyl Code in Precision Oncology: Mechanistic Insights from Dietary and Metabolic Factors

Nutrients, Journal Year: 2024, Volume and Issue: 16(3), P. 396 - 396

Published: Jan. 30, 2024

Cancer etiology involves complex interactions between genetic and non-genetic factors, with epigenetic mechanisms serving as key regulators at multiple stages of pathogenesis. Poor dietary habits contribute to cancer predisposition by impacting DNA methylation patterns, non-coding RNA expression, histone landscapes. Histone post-translational modifications (PTMs), including acyl marks, act a molecular code play crucial role in translating changes cellular metabolism into enduring patterns gene expression. As cells undergo metabolic reprogramming support rapid growth proliferation, nuanced roles have emerged for dietary- metabolism-derived acylation progression. Specific types acylation, beyond the standard acetylation shed light on how metabolites reshape gut microbiome, influencing dynamics repertoires.
