Herbal remedies against gastric cancer in experimental rats

Abstract Gastric cancer is the fourth most prevalent cancer worldwide, which claims more than 700,000 lives every year. However, the current chemical and surgical management of this mortal cancer remains far from successful. A recent safe approach to preventing or treating tumorigenesis has been the re-introduction of traditional herbal medicine, taking advantage of efficient, yet natural healthy products. In this review, we have focused on a number of such popular agents, mostly introduced by the Traditional Chinese medicine (TCM), which have exhibited highly significant preventive/therapeutic effects against various gastric pathologies, ranging from gastritis to premalignant lesions and confirmed malignancies, in experimental rats. The underlying mechanisms of action seem to concentrate on shifting the balance between in vivo oxidant and anti-oxidant activities. In addition, the existing reports on the potential toxicity of these compounds, as well as their interactions with chemical drugs, have been presented. However, far more details are required to recommend herbal medicine as an effective and reliable plan of action in gastric cancer management.

Authors: Annibale B, Esposito G, Lahner E Abstract SUMMARYIntroduction: Atrophic gastritis (AG) is a complex syndrome which arise as consequence of H. pylori infection or in the context of gastric autoimmunity. It often deserves a benign course, but may lead to potentially life-threatening complications: cancer and anaemia. This review aims to address traditional and innovative knowledge on this often under-diagnosed disorder.Areas covered: This review covers clinical presentation, risk factors, diagnosis and management of AG and provides an updated resource for clinicians to get insight in this challenging disorde...

This study investigated the molecular targets of the component herbs of QLSP in preventing precancerous lesions based on network pharmacology. Network pharmacology analysis revealed that the 6 herbs regulated multiple CAG-related genes, among which the most important were cancer-related pathway (apoptosis, p53, and VEGF) and epithelial cell signaling in Helicobacter pylori infection. Further animal experiments showed that the expression of survivin and p53 in precancerous lesions of CAG rats was significantly increased which was suppressed by QLSP. Moreover, telomerase activity was inhibited in precancerous lesions of CAG ...

Forty-five years have passed since Correa et  al1 proposed their hypothesis on the histopathological cascade leading to gastric adenocarcinoma claiming that gastric cancer usually resulted from chronic gastritis, subsequently leading to gland loss or atrophy, intestinal metaplasia, dysplasia, and eventually invasive cancer. The most common ri sk factor for gastritis soon revealed to be the colonization with Helicobacter pylori.2 Most infections occur during childhood and remain for life. They are almost invariably associated with chronic gastritis, which may eventually lead to a loss of mucosal glands.

Macrophages have a major role in infectious and inflammatory diseases, and the available data suggest that Helicobacter pylori persistence can be explained in part by the failure of the bacterium to be killed by professional phagocytes. Macrophages are cells ready to kill the engulfed pathogen, through oxygen-dependent and -independent mechanisms; however, their killing potential can be further augmented by the intervention of T helper (Th) cells upon the specific recognition of human leukocyte antigen (HLA)-II–peptide complexes on the surface of the phagocytic cells. As it pertains to H. pylori, the bacterium is eng...

ConclusionsE-stasis after LPPG occurs in 7.6% of patients. Age, DM, and intraabdominal infection are significantly related to E-stasis. E-stasis is associated with poorer nutritional and functional outcomes even at 1  year postoperatively.

CONCLUSIONS The LncRNA expression profile between EGC and gastritis tissues was significantly different. LOC389332 was potential non-coding oncogenes in gastric cancer, and it may perform its function through altering cell membrane function, signal transmission, and cell adhesion.

Conclusion: According to our analysis, there was no correlation between coinfection and polymorphisms in genes encoding IL-10 and IL-1RN. We conclude that various factors can be involved in the development of gastric diseases. PMID: 31885568 [PubMed]

ConclusionsA genetic origin that drives mitochondria alteration would initiate the gastric chronic inflammation instead of the classical IL-17 secretion-mediated mechanism explanation. Gastric euchlorhydria restoration is suggested to be indicated for mitochondrial recover. Our results open a new window to understand gastric neoplasms formation but also the inflammatory mechanisms and autoimmune disorders conducted by genetic origin that composes a premalignant scenario.

CONCLUSIONS: Specific signs and symptoms, chronic conditions, a greater comorbidity burden, and specific pharmacological treatments registered in primary care databases represent relevant predictors and correlates of incident IDA in older people in Europe. General practitioners might employ this information to obtain early diagnosis of IDA in community-dwelling older adults. PMID: 31893385 [PubMed - as supplied by publisher]

In this study, 43 five- and six-genotype combinations were found among 224 strains. The highest frequencies were observed for vacA s1m2i2d2c2 (85/224, 37.9%), s1m2i2d2c2cagA (48/222, 21.6%), s1m1i1d1c1 (40/224, 17.9%) and s1m1i1d1c1cagA (35/222, 15.8%). Logistic regression analysis showed that vacA s1m1i1d1c1, s1m2i1d2c1, s1m2i2d2c1, and s1m2i2d2c1cagA had a high prevalence in GC patients compared to non-atrophic gastritis patients (p
