What is the role of BMPs in gastric cancer? 


Best insight from top research papers

Bone morphogenetic proteins (BMPs) play a multifaceted role in gastric cancer. BMP2 acts as a tumor suppressor by downregulating EZH2 and H3K27me3 through a non-SMAD BMP pathway, inhibiting cell proliferation . Conversely, BMP5 is reduced, while ACVRL1, ACVR1, TGFBR1, and BMPR2 are increased in gastric tumors, with BMPs and their receptors associated with poorer overall survival and promoting invasion, EMT, and stemness . BMP4 is frequently overexpressed in GC, correlating with poor prognosis, and promotes EMT and metastasis by upregulating ID1 expression . SOSTDC1 acts as a tumor suppressor by inhibiting c-Jun activation and promoting lung metastasis in GC . Additionally, BMP10 suppresses GC growth and migration by negatively regulating beta-catenin/TCF signaling . Overall, BMPs exhibit both tumor-suppressive and tumor-promoting functions in gastric cancer progression.

BMP10 inhibits growth and migration of gastric cancer cells, indicating a tumor-suppressive role of BMPs in gastric cancer progression.
BMP antagonist SOSTDC1 restrains gastric cancer by inactivating c-Jun signaling, rather than canonical SMAD-dependent BMP pathway, highlighting a noncanonical BMP role in gastric cancer progression.
BMP4 promotes gastric cancer metastasis by inducing EMT via upregulating ID1 expression. It plays a crucial role in EMT progression and metastasis in gastric cancer.
BMPs in gastric cancer have dual roles: inhibiting proliferation but promoting invasion, EMT, and stemness. Elevated BMP receptor expression is linked to angiogenesis and lymphangiogenesis, aiding tumor progression.
BMP2 acts as a tumor suppressor in gastric cancer by inhibiting cell proliferation through downregulating EZH2 and H3K27me3 via the non-SMAD BMP pathway, suggesting a potential therapeutic target.

How do Nitrous acid compounds contribute to the development of gastric cancer?5 answersNitrous acid compounds, specifically nitrite and nitrate, play a significant role in the development of gastric cancer. Research indicates that high or moderate nitrite intake is associated with an increased risk of gastric cancer, while high or moderate nitrate intake is linked to a reduced risk of the disease. Moreover, N-methyl-N-nitro-N-nitroguanidine (MNNG), a nitrosamine compound, is identified as a major risk factor for gastric cancer, emphasizing the harmful impact of nitrous acid compounds on gastric health. Additionally, the expression of NOS3, involved in nitric oxide generation, is found to influence the occurrence and progression of stomach adenocarcinoma, highlighting the role of nitric oxide in gastric cancer development. These findings underscore the intricate relationship between nitrous acid compounds and gastric cancer pathogenesis.
How does gastric cancer affect nutrition?5 answersGastric cancer significantly impacts nutrition in patients. Studies have shown that gastric cancer patients are at high risk of malnutrition. Malnutrition negatively affects clinical outcomes, quality of life, and treatment tolerance, leading to poor physical activity and severe toxicity during chemotherapy or radiation therapy. Factors influencing nutritional status include symptom severity, difficulty in diet preparation, and employment status. Early identification of malnutrition risk is crucial to initiate appropriate nutritional support, which can reduce hospitalization length, treatment-related toxicity, and improve quality of life and treatment outcomes. Nutritional interventions, such as immunonutrition, play a vital role in preparing patients for surgery and aiding in postoperative recovery. Therefore, a comprehensive approach to nutritional support is essential in managing gastric cancer patients.
What are the molecular mechanisms underlying gastric cancer metastasis?4 answersGastric cancer (GC) metastasis is driven by various molecular mechanisms. Abnormal gene expression plays a crucial role in the occurrence of liver metastasis in GC patients. The liver microenvironment undergoes changes that create a favorable condition for GC cells to colonize and grow. Peritoneal metastasis (PM) is another common pattern of GC metastasis, and key molecules are involved in the sequential processes of PM, including angiogenesis and adhesion to the peritoneum. In some GC patients, invasion and metastasis can occur independently, suggesting different molecular mechanisms at play. The expression of chemokine receptor CXCR2 is upregulated in early lymph node-positive GC, indicating its potential role in promoting lymph node metastasis. Understanding the molecular processes and immunologic aspects of metastasis is crucial for developing effective therapeutic strategies for GC. Autochthonous cancer models have been developed to study the behavior and therapeutic response of metastatic gastric carcinoma, providing insights into the genotype, organotropism, and immune surveillance of metastatic cells.
How pro-inflammatory cytokines are involved in gastric cancer?4 answersPro-inflammatory cytokines play a significant role in gastric cancer development and progression. Inflammation induced by Helicobacter pylori infection leads to the generation of an inflammatory microenvironment, which promotes gastric tumorigenesis. Inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, IL-6, and IL-8 support the growth and tumorigenicity of gastric cancer cells. These cytokines activate signaling pathways, including NF-κB and STAT3, which contribute to tumor progression. Additionally, pro-inflammatory cytokines are associated with oxidative stress and DNA damage in gastric tumors. Elevated levels of pro-inflammatory cytokines, such as TNF-α, IL-6, and IFN-γ, are observed in gastric cancer patients, suggesting their potential as biomarkers for predicting gastric tumor development. Targeting inflammatory pathways, including COX-2 and cytokines, may be an effective strategy for preventing gastric cancer. Overall, pro-inflammatory cytokines play a crucial role in gastric cancer by promoting inflammation, tumor growth, and chemoresistance.
Cancer-suppressing miR-520-3p gene inhibits proliferation, migration, and invasion of gastric cancer cells through targeted regulation of KLF75 answersThe miR-520-3p gene has been found to inhibit the proliferation, migration, and invasion of gastric cancer (GC) cells by targeting the Kruppel-like factor 7 (KLF7) gene. The expression of miR-520-3p is significantly downregulated in GC tissues and cells, while the expression of KLF7 is greatly upregulated in GC tissues. Upregulation of miR-520-3p leads to the inhibition of GC cell proliferation, vitality, and invasion both in vivo and in vitro. MiR-520-3p can adsorb KLF7 in GC cells, and KLF7 can reverse the inhibitory effect of miR-520-3p overexpression on GC cell proliferation. These findings suggest that miR-520-3p may serve as a novel prognostic biomarker and potential therapeutic target for GC.
What roles STn can play in gastric cancer?5 answersSTn, a carbohydrate antigen, has been implicated in gastric cancer. It is associated with cancer stem cells and the tissue microenvironment, and its altered expression is linked to gastric cancer metastasis and invasion. lncRNAs, such as HOTAIR, HULC, LINC00152, MALAT2, H19, GHET1, and GACAT3, have been shown to have oncogene activities in gastric cancer, while others like LEIGC, GAS5, and FER1L4 have been identified as tumor suppressors. These lncRNAs play important roles in signaling pathways, crosstalk with microRNAs, and regulating epithelial-to-mesenchymal transition. Additionally, the tumor microenvironment, including interactions between the tumor and surrounding stromal cells, as well as angiogenesis, contribute to gastric cancer pathogenesis. Chronic inflammation, particularly triggered by H. pylori infection, is a significant cause of gastric cancer and can impact gastric stem cells and the stroma. Organoid models have provided insights into the role of host genetics, bacterial factors, and the chronic inflammatory milieu in gastric cancer initiation.
