Beta-carotene and its protective effect on gastric cancer

摘要

Beta-carotene is an important natural pigment that is very beneficial to human health.It is widely found in vegetables and fruits.The three main functions are antioxidant effects,cell gap junction-related functions and immune-related functions.Because of its diverse functions,beta-carotene is believed to prevent and treat many chronic diseases.Gastric cancer is one of the most important diseases it can treat.Gastric cancer is a type of cancer with a high incidence.Its etiology varies,and the pathogenesis is complex.Gastric cancer seriously affects human health.The role of beta-carotene,a natural nutrient,in gastric cancer has been explored by many researchers,including molecular mechanisms and epidemiological studies.Molecular studies have mainly focused on oxidative stress,cell cycle,signal transduction pathways and immune-related mechanisms of beta-carotene in gastric cancer.Many epidemiological surveys and cohort studies of patients with gastric cancer have been conducted,and the results of these epidemiological studies vary due to the use of different research methods and analysis of different regions.This paper will summarize the results of these studies,mainly in terms of molecular mechanisms and epidemiological research results,which will provide a systematic basis for future studies of the treatment and prognosis of gastric cancer.This paper will help researchers identify new research directions.
