The microbiota is garnering progressively greater consideration as an essential facet of the tumor microenvironment that regulates tumor proliferation and affects cancer prognosis. Microbial populations that inhabit different body locations are involved in the carcinogenesis and tumor progression of their corresponding malignancies. It has been learned that the microbial populations primarily thriving within tumors are tumor-type specific. Mechanistic studies have revealed that the tumor-associated microbiota contributes to playing a pivotal role in the establishment of the tumor microenvironment, regulation of local immunity, modulation of tumor cell biology, and directly influences the therapeutic efficacy of drug treatment for tumors. This review article incorporates the pertinent studies on recent advancements in tumor microbiome studies, the interplay between the intratumor microbiota and cancer, and, discusses their role and mechanism of action in the emergence and treatment of cancer, and their relationship to clinical characteristics.

Cancer remains one of the leading causes of death worldwide, despite advances in treatments such as surgery, chemotherapy, radiotherapy and immunotherapy. The role of the gut microbiota in human health and disease, particularly in relation to cancer incidence and treatment response, has gained increasing attention. Emerging evidence suggests that dietary fibre, including prebiotics, can modulate the gut microbiota and influence antitumour effects.

Background: Serovar Typhimurium (. Typhimurium) infection can cause inflammation and oxidative stress in the body, leading to gastroenteritis, fever and other diseases in humans and animals. More and more studies have emphasized the broad prospects of probiotics in improving inflammation and oxidative stress, but the ability and mechanism of (LA) to alleviate the inflammatory/oxidative reaction caused by pathogens are still unclear.

Background: Immune checkpoint inhibitors (ICIs) have transformed oncological treatment by modulating immune responses against tumors. However, their efficacy is subject to inter-patient variability and is associated with immune-related adverse events (irAEs). The human gut microbiota, a complex microbial ecosystem, is increasingly implicated in modulating responses to ICIs.

Small-molecule pectin (SMP) extracted from the leaves of Premna ligustroides Hemsl, with a molecular weight range of 5000-35,000 Da, has demonstrated anti-inflammatory and lipid-lowering properties in vitro. This study explored the effects of SMP on hypercholesterolemia in mice, with a focus on inflammation, lipid profiles, and cholesterol metabolism. Mice received SMP at doses of 607, 303, and 152 mg/kg body weight.

The tumor microenvironment has recently been well-studied in various gastrointestinal cancers, including colorectal cancer (CRC). The gut microbiota, a collection of microorganisms in the human gastrointestinal tract, is one of the microenvironments associated with colon carcinogenesis. It has been challenging to elucidate the mechanisms by which gut microbiota contributes to carcinogenesis and cancer progression due to complex interactions with the host, including its metabolites and immune and inflammatory responses.
