ABSTRACT

The progression from gastric mucosal inflammation to cancer signifies a pivotal event in the trajectory of gastric cancer (GC) development. Chinese medicine (CM) exhibits unique advantages and holds significant promise in inhibiting carcinogenesis of the gastric mucosa. This review intricately examines the critical pathological events during the transition from gastric mucosal inflammation-cancer transformation (GMICT), with a particular focus on pathological evolution mechanisms of spasmolytic polypeptide-expressing metaplasia (SPEM). Moreover, it investigates the pioneering applications and advancements of CM in intervening within the medical research domain of precancerous transformations leading to GC. Furthermore, the analysis extends to major shortcomings and challenges confronted by current research in gastric precancerous lesions, and innovative studies related to CM are presented. We offer a highly succinct yet optimistic outlook on future developmental trends. This paper endeavors to foster a profound understanding of forefront dynamics in GMICT research and scientific implications of modernizing CM. It also introduces a novel perspective for establishing a collaborative secondary prevention system for GC that integrates both Western and Chinese medicines.

ABSTRACT

One of the difficulties in the treatment of hepatocellular carcinoma is that it is impossible to eliminate the inhibitory effect of the tumor microenvironment on immune response. Therefore, it is particularly important to understand the formation process of the tumor microenvironment. Chronic inflammation is the core factor of cancer occurrence and the leading stage of inflammation-cancer transformation, and the natural killer cell subsets play an important role in it. Our study confirmed that in the stage of chronic liver injury, the local immunosuppressive microenvironment of the liver (i.e. the damaged microenvironment) has been formed, but this inhibitory effect is only for peripheral natural killer cells and has no effect on tissue-resident natural killer subsets. The markers of damage microenvironment are the same as those of tumor microenvironment.

ABSTRACT

As the pace of society increases and lifestyles change, the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer, and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them, signal transducer and activator of transcription (STAT) proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information, which can regulate downstream cell proliferation, apoptosis, cell migration, invasion, angiogenic factors, etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine, "heat toxicity" in "cancer toxicity" corresponds to inflammation, which is closely related to tumor development. As a major link associated with the inflammatory response, the STAT family has a promising role in the development and treatment of a variety of tumors, but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer, and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins, but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer, this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years, aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

ABSTRACT

BACKGROUND: JianPi QingRe HuaYu Methods (JQH) have been long used to treat chronic atrophic gastritis (CAG) and precancerous lesions of gastric cancer (PLGC). However, whether JQH can inhibit the transformation of gastritis to gastric cancer (GC) remains unclear. METHODS: Herein, we first retrieved the active ingredients and targets of JQH from the TCMSP database and the targets related to the gastric inflammation-cancer transformation from public databases. Differentially expressed genes (DEGs) related to gastric inflammation-cancer transformation were identified from the Gene Expression Omnibus (GEO) database. Then, we obtained the potential therapeutic targets of JQH in treating gastric inflammation-cancer transformation by intersecting drugs and disease targets. The Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses of the potential therapeutic targets were conducted using R software. Next, we conducted molecular docking and in vitro experiments to validate our results. RESULTS: We obtained 214 potential therapeutic targets of JQH by intersecting drugs and disease targets. We found that the potential mechanisms of JQH in treating gastric inflammation-cancer transformation might be related to JAK-STAT, Wnt, p53 and VEGF signaling pathways. The molecular docking indicated that quercetin, as the main active ingredient of JQH, might inhibit gastric inflammation-cancer transformation by binding with specific receptors. Our experimental results showed that quercetin inhibited cells proliferation (P < 0.001), promoted cell apoptosis (P < 0.001), reduced the secretion of pro-inflammatory cytokines (P < 0.001) and promoted the secretion of anti-inflammatory cytokines (P < 0.001) in MNNG-induced GES-1 cells. Furthermore, quercetin inhibited cells proliferation (P < 0.001) and reduced mRNA and protein level of markers of PLGC (P < 0.001) in CDCA-induced GES-1 cells. CONCLUSION: These results provide the material basis and regulatory mechanisms of JQH in treating gastric inflammation-cancer transformation.

ABSTRACT

BACKGROUND: There is no research to prove the association between irritability and lung cancer, our study performed a Mendelian randomization (MR) approach to elucidate the causal relationship of irritability with lung cancer risk. METHODS: Genome-wide association studies (GWAS) data of irritability, lung cancer and gastroesophageal reflux disease (GERD) were downloaded from a public database for two-sample MR analysis. Independent single-nucleotide polymorphisms (SNPs) associated with irritability and GERD were selected as instrumental variables (IVs). Inverse variance weighting (IVW) and weighted median method were used to analyze causality. RESULTS: There is an association between irritability and lung cancer risk (ORIVW = 1.01, 95% CI = [1.00, 1.02], P = 0.018; ORweighted median = 1.01, 95% CI = [1.00, 1.02], P = 0.046), and GERD might account for about 37.5% of the association between irritability and lung cancer. CONCLUSIONS: This study confirmed the causal effect between irritability and lung cancer through MR analysis, and found that GERD played an essential mediating role in this relationship, which can partly indicate the role of the "inflammation-cancer transformation" process in lung cancer.

ABSTRACT

Hepatocellular carcinoma (HCC) is the terminal phase of multiple chronic liver diseases, and evidence supports chronic uncontrollable inflammation being one of the potential mechanisms leading to HCC formation. The dysregulation of bile acid homeostasis in the enterohepatic circulation has become a hot research issue concerning revealing the pathogenesis of the inflammatory-cancerous transformation process. We reproduced the development of HCC through an N-nitrosodiethylamine (DEN)-induced rat model in 20 weeks. We achieved the monitoring of the bile acid profile in the plasma, liver, and intestine during the evolution of "hepatitis-cirrhosis-HCC" by using an ultra-performance liquid chromatography-tandem mass spectrometer for absolute quantification of bile acids. We observed differences in the level of primary and secondary bile acids both in plasma, liver, and intestine when compared to controls, particularly a sustained reduction of intestine taurine-conjugated bile acid level. Moreover, we identified chenodeoxycholic acid, lithocholic acid, ursodeoxycholic acid, and glycolithocholic acid in plasma as biomarkers for early diagnosis of HCC. We also identified bile acid-CoA:amino acid N-acyltransferase (BAAT) by gene set enrichment analysis, which dominates the final step in the synthesis of conjugated bile acids associated with the inflammatory-cancer transformation process. In conclusion, our study provided comprehensive bile acid metabolic fingerprinting in the liver-gut axis during the inflammation-cancer transformation process, laying the foundation for providing a new perspective for the diagnosis, prevention, and treatment of HCC.

ABSTRACT

Gastric cancer (GC) is a common gastrointestinal tumor. Gastric precancerous lesions (GPL) are the last pathological stage before normal gastric mucosa transforms into GC. However, preventing the transformation from GPL to GC remains a challenge. Traditional Chinese medicine (TCM) has been used to treat gastric disease for millennia. A series of TCM formulas and active compounds have shown therapeutic effects in both GC and GPL. This article reviews recent progress on the herbal drugs and pharmacological mechanisms of TCM in preventing the transformation from GPL to GC, especially focusing on anti-inflammatory, anti-angiogenesis, proliferation, and apoptosis. This review may provide a meaningful reference for the prevention of the transformation from GPL to GC using TCM.

ABSTRACT

Gastric ''inflammation-cancer'' transformation stars from inflammation and ends as gastric cancer (GC), and the pathogenesis is still unclear. In China, GC features high morbidity and mortality and poor prognosis, influencing the quality of life and physical and mental health of patients. Therefore, it is of great significance to construct the prevention and treatment system for GC. Chronic atrophic gastritis (CAG) plays a key role in the occurrence, development, and outcome of gastric ''inflammation-cancer'' transformation. Modern therapies for CAG generally aim at eliminating causes and alleviating clinical symptoms, which show satisfactory short-term efficacy, but the reverse and recurrence are common. Based on the holistic view, syndrome differentiation-based treatment, and the ''inflammation-cancer'' transformation in modern medicine, traditional Chinese medicine emphasizes both prevention and treatment, with individualized therapies for CAG and GC to control the transformation. According to the pathogenesis of CAG-asthenia in origin and sthenia in superficiality and deficiency-excess in complexity, this study proposed the theory of spleen deficiency and pathogen stagnation in CAG, and believed spleen deficiency, pathogen, and stagnation are respectively the root cause of, the main factor of, and the key to ''inflammation-cancer'' transformation, respectively. Spleen deficiency and pathogen stagnation are closely related to the process of the transformation. For the treatment, the spleen-invigorating and pathogen-eliminating method should be used for invigorating the spleen to consolidate original Qi, improve the blood supply in stomach, and regulate immunity, and eliminating the pathogen to relieve stagnation, reduce the occurrence of non-controllable inflammation, and improve inflammatory micro-environment. As a result, the gastric inflammation is controlled at the early stage and the gastric ''inflammation-cancer'' transformation is blocked. The gastric mucosal lesions are blocked, delayed, or even reversed. This study provides a new idea in clinical diagnosis and treatment of CAG and in the prevention of GC.

ABSTRACT

Chronic obstructive pneumonia cancer transformation refers to the malignant transformation of long-term repeated chronic inflammation of the lung. Traditional Chinese Medicine believes that the etiology and pathogenesis of chronic obstructive pneumonia cancer transformation always belong to the deficiency of origin and excess of signs. Chronic obstructive pulmonary disease causes damage to the qi of the lung, spleen and kidney. Qi is yang, and qi deficiency leads to yang deficiency. Yang deficiency and abnormal warm would result in qi stagnation, phlegm coagulation and blood stasis. It is the key to the transformation of chronic obstructive pneumonia cancer. Kidney yang is the root of yang qi. Deficiency of kidney yang is the initiating factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of lung yang is the fundamental factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of kidney yang and deficiency of spleen yang are the driving factors for the transformation of chronic obstructive pneumonia cancer. Therefore, this article discussed the role of kidney yang in the transformation of chronic obstructive pneumonia cancer from the theory of "Qi Zhu Xu Zhi", in order to broaden the thinking of clinical diagnosis and treatment of the disease.

ABSTRACT

Breast cancer as the most common cancer in women has become the leading cause of cancer death for women. Although many inflammatory factors increase the risk of breast cancer, there are very few studies on the mechanisms by which inflammation affects the initiation and progression of breast cancer. Here, we profiled and compared the transcriptome of normal tissues, inflammatory breast tissues, benign breast tumors, and malignant breast tumors. To find key regulatory factors, a protein interaction network between characteristic modules in inflammatory lesions and ER-negative (ER-) breast cancer was constructed and inflammation-cancer interface genes were identified. We found that the transcriptional profile of inflammatory breast tissues was similar with ER- malignant tumors, featured with low ER expression levels and similar immune signaling pathway activation. Through comprehensive protein network analysis, we identified the interface genes and chemokine signaling pathway that have the potential to promote inflammatory cancer transformation. These interface genes could be used as a risk factor to provide a certain basis for the clinical early detection and treatment of breast cancer. This is the first study to explore the association between breast inflammatory lesions and breast cancer at the transcriptome level. Our inflammation data and research results provide a basis for future inflammation-cancer transformation analysis.
