ABSTRACT
Gastric cancer （GC） is a common malignant tumor of the digestive tract. T helper cells 17 （Th17） and T regulatory cells （Treg） are differentiated subsets of CD4+T cells. Th17/Treg imbalance has been shown to be closely related to the progression of GC. Traditional Chinese medicine （TCM） can not only improve the survival prognosis of GC patients， but also play a role in enhancing the efficacy and reducing the toxicity of postoperative chemotherapy for GC. This paper systematically sorted out the action rules of TCM in the intervention of GC by regulating Th17/Treg balance. The results showed that the TCM compound could regulate the balance of GC Th17/Treg by invigorating the spleen and invigorating Qi， warming Yang， removing blood stasis and detoxifying. The mechanism of regulating Th17/Treg balance in the intervention of GC is mainly to inhibit the excessive differentiation of Th17 and Treg and the overexpression of transcription factors and cytokines， reverse the excessive drift of GC Th17/Treg balance to Th17 or Treg， and thus restore the immune balance of GC Th17/Treg.
ABSTRACT
Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise， and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa， causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue， which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B （NF-κB） signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation， autophagy， apoptosis， and inflammatory response of esophageal epithelial cells and tumor cells， accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently， there is no specific treatment for reflux esophagitis and esophageal cancer， and large side effects often appear. Therefore， finding a promising and safe drug remains a top priority. In recent years， traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway， and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， but there is a lack of comprehensive and systematic elaboration. Therefore， this paper summarized the relevant studies in recent years， analyzed the relationship among NF-κB signaling pathway， reflux esophagitis， esophageal cancer， and transformation from inflammation to cancer， and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer， so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.
ABSTRACT
Esophageal cancer （EC） is a common malignant tumor of the digestive system with an extremely poor prognosis. MicroRNA （miRNA） is an important regulator in tumor occurrence and development， and can participate in malignant biological behaviors such as tumor cell proliferation， invasion， metastasis and apoptosis. Traditional Chinese medicine has the characteristics of accurate curative effects， wide range of effects， and few side effects. The review uses miRNA as the entry point to systematically elaborate on the mechanism of traditional Chinese medicine-mediated miRNA intervening in EC. The results showed that active ingredients of traditional Chinese medicine （including curcumin， Tussilago farfara polysaccharides， Atractylodes macrocephala polysaccharides and ophiopogonin B） and Dougen guanshitong oral liquid could up-regulate the expressions of miRNAs such as miRNA-532-3p （miR-532-3p）， miR-551b-3p， miR-99a， miR-34a， miR-199a-3p and miR-377； and the active ingredients/parts of traditional Chinese medicine （including chrysin and Actinidia arguta extract）， and Chinese herbal formulas （including Chaihu shugan san combined with Xuanfu daizhe decoction and Modified jupi zhuru decoction） could down-regulate the expressions of miRNAs such as miR-199a-3p， miR-451 and miR-21， which could regulate the expressions of signaling pathways （phosphoinositide 3-kinase/protein kinase B， etc.） or their downstream protein（zinc-finger and homeobox protein 1， etc.） or enzymes（thymidine kinase-1， etc.）， inhibit the proliferation， invasion and metastasis of EC cells and induce apoptosis， thereby ultimately achieving the purpose of preventing the disease from aggravating.
ABSTRACT
Colorectal cancer （CRC） is one of the leading causes of cancer-related deaths worldwide， with increasing incidence and mortality rates. The disease often develops covertly and lacks specific symptoms in its early stages， leading to late-stage diagnoses in most patients. It has become a prominent research topic in the field of digestive system tumors. The exact mechanisms underlying CRC are not yet clear and involve factors such as genetics， gene mutations， inflammatory responses， and aberrant activation of tumor-related signaling pathways. Nuclear factor-kappa B （NF-κB） is a crucial transcription factor that participates in various biological processes， including inflammatory responses， immune responses， cell proliferation， and apoptosis. Research suggests that NF-κB， serving as a molecular link between inflammation and cancer， is highly expressed in CRC. It promotes the occurrence and development of CRC by regulating the activity of target genes such as cell pro-inflammatory factors， chemokines， angiogenic factors， metastasis factors， and anti-apoptotic proteins. Currently， common treatments for CRC include surgery， radiation therapy， and chemotherapy drugs like 5-fluorouracil. However， these treatments have limitations such as significant adverse reactions， high metastasis rates， and the development of drug resistance. Therefore， the search for effective， low-adverse-reaction drugs to replace or supplement current treatments is essential. In recent years， traditional Chinese medicine （TCM） has shown some effectiveness in preventing and treating CRC. TCM has been found to inhibit the growth of CRC cells by modulating the NF-κB signaling pathway， playing a positive role in the occurrence and progression of CRC. Based on the asthenia in origin and sthenia in superficiality and deficiency-excess in complexity in CRC， this article summarized and analyzed the mechanisms and effects of TCM interventions targeting the NF-κB signaling pathway in CRC， and reviewed advances of 10 Chinese medicinal compound formulas and 37 Chinese medicinal monomer components of different types， including flavonoids， phenols， alkaloids， glycosides， and terpenoids with the effects of dispelling pathogenic factors， reinforcing healthy qi， and removing toxins in the prevention and treatment of CRC by targeting the NF-κB pathway. It is found that Chinese medicine can inhibit CRC cell proliferation， invasion， metastasis， angiogenesis， and inflammation by modulating the NF-κB signaling pathway， induce cell apoptosis， restore drug and radiation sensitivity， and counteract CRC. This article is expected to provide insights and references for the in-depth exploration and treatment of CRC mechanisms.
ABSTRACT
Pancreatic cancer is one of the most destructive malignant tumors； the pathogenesis of this disease is complex and is closely related to genetic susceptibility， chronic pancreatitis， and gene mutations in signaling pathways. The phosphoinositide 3- kinase （PI3K）/protein kinase B （Akt） signaling pathway is a classical cancer signaling pathway that is aberrantly activated in pancreatic cancer cells. In recent years， it has been found that traditional Chinese medicine （TCM） monomers show special activity in the treatment of pancreatic cancer and can be potential drug for the treatment of pancreatic cancer. Based on PI3K/Akt signaling pathway， this paper summarizes the mechanism of TCM monomer intervening in pancreatic cancer and finds that TCM monomer of alkaloids （sinomenine， dictamnine， dauricine， etc.）， terpenoids （saikosaponin A， linderalactone， isoalantolactone， etc.）， phenols （6-gingerol， curcumin， pterostilbene， etc.）， flavonoids （fisetin， kaempferol， quercetin， etc.） and quinones （β-hydroxyisovaleryl shikonin， rhein， lucidone， etc.） can inhibit the proliferation， invasion and migration of pancreatic cancer cells， regulate autophagy and apoptosis， and then inhibit the pathological process of pancreatic cancer by inhibiting PI3K/Akt signaling pathway.
