Summary: Integrins are crucial for cell adhesion, migration, and positioning. Studies have shown that the expression levels of Integrin αVβ6 are closely related to malignant diseases and patient prognosis. It plays a significant role in cancer progression and the activation of transforming growth factor β(TGF-β). While essential for normal function in healthy individuals, it can also be a target for cancer treatment.

Summary: In this study, macrophage membrane-coated liposome-based biomimetic nanoparticles were developed to improve the in vivo bioavailability of Naringenin (NG). The nanoparticles exhibited good biocompatibility, stability, and pH-responsive drug release kinetics, leading to higher cellular uptake in vitro. The anti-metastatic efficacy of NG-loaded biomimetic nanoparticles was confirmed in experimental models, indicating its potential for reducing metastatic colonies in the lungs.

Summary: The knockdown of ITGAV in PDA cells significantly reduces primary tumor growth, peritoneal carcinomatosis, and spontaneous pulmonary metastasis. ITGAV activates latent TGF-beta and drives epithelial-mesenchymal transition. Combined depletion of ITGAV on tumor cells and E- and P-selectins in the tumor-host almost abolishes intraperitoneal spread.

Summary: This study investigates the role of SPC25 in promoting hepatocellular carcinoma (HCC) progression. It is found that SPC25 is highly expressed in HCC and associated with poor prognosis and metastasis. Silencing SPC25 inhibits invasion and migration of HCC cells in vitro and in vivo. The study also reveals that SPC25 affects genes associated with extracellular matrix-integrin interactions, and upregulation of ITGB4 partially reverses the decline in cell invasion and migration capacities caused by SPC25 silencing. Blocking both SPC25 and ITGB4 reduces phosphorylation of downstream elements in the integrin pathway. Overall, this research highlights the important role of SPC25 as both a prognostic indicator and a promoter of metastasis in HCC.

Summary: It has been discovered that ANGPTL3 plays an oncogenic role in several types of human malignancies. This study found that ANGPTL3 is highly expressed in cervical cancer cells and silencing ANGPTL3 can inhibit cell proliferation, migration, invasion, and angiogenesis. The inhibitory effect of ANGPTL3 can be offset by upregulating the expression of alpha v beta 3, which also promotes blood vessel formation and the secretion of VEGF and VEGFR2 in cervical cancer cells.

Summary: Baicalein was found to exhibit cytotoxicity and anti-proliferative activity on nasopharyngeal carcinoma cells, and significantly inhibited metastatic phenotypes. Transcriptome profiling revealed that baicalein inhibited metastatic phenotypes by modulating the expression of integrin beta 8.

Summary: The study evaluated a high-affinity molecular probe targeting PDAC tumors, showing promising tumor accumulation and moderate, rapidly declining kidney uptake for the tracer Lu-177-DOTA-integrin alpha v beta 6 knottin. These results support further preclinical treatment studies to establish therapeutic efficacy.

Summary: The study demonstrated that Thrombospondin-2 could promote the expression of IL-6 in osteoarthritis synovial fibroblasts in a dose-dependent manner, potentially involving signaling pathways such as integrin alpha(v)beta(3), PI3K, Akt, and NF-kappa B. Additionally, in a rat model of ACLT surgery, it was found that TSP2 neutralizing antibody had protective effects on cartilage destruction during OA progression.

Summary: The purpose of this study was to validate the in-house kit-like synthesis of Ga-68-Trivehexin and evaluate its uptake in patients with integrin alpha v beta 6 expressing head and neck and pancreatic cancer. The results showed intense radiotracer uptake in tumors and no uptake in healthy tissues. PET/CT imaging at 60 minutes post injection was found to be the optimal time for imaging tumors with Ga-68-Trivehexin. This study demonstrates that Ga-68-Trivehexin is a promising agent for noninvasive molecular imaging of integrin alpha v beta 6 expressing tumors.

Summary: Integrin Alpha v Beta 6 is primarily expressed in solid epithelial tumors, such as cholangiocarcinoma, pancreatic cancer, and colorectal cancer. It is considered a potential and promising molecular marker for the early diagnosis and treatment of cancer. This review focuses on its role in cancer progression and its potential applications in molecular imaging and therapeutic targets.

Summary: This study uncovered the emerging role of HN1 in promoting dedifferentiation of anaplastic thyroid cancer (ATC) cells. HN1 negatively regulated the thyroid differentiation markers and had an inhibitory effect on the transcriptional activation of CTCF, thereby influencing the chromatin accessibility of thyroid differentiation genes.

Summary: This study found that serum 2-OG levels in cholangiocarcinoma patients are associated with the effectiveness of chemotherapy. Patients with progressive disease showed significantly higher levels of serum 2-OG compared to stable disease and partial response patients. The study also revealed that overexpression of ASPH mimics the effects of 2-OG, and knockdown of ASPH improves chemotherapy. Targeting ASPH enhances the effects of chemotherapy by modulating ATM and ATR, two key regulators of DDRs.
