ITGA2B (Integrin Subunit Alpha 2b)

Despite the small sample size and absence of functional experiments, our results suggest that Pazopanib promotes cytotoxic immune programs but, by six months, reprograms PLT-EVs towards different adhesion characteristics contributing to Treg and MDSC expansion while suppressing NK activity. PLT-EVs may influence the balance between immune activation and suppression during anti-angiogenic therapy, suggesting PLT-EVs as biomarkers and therapeutic targets in mRCC.

Overall, these findings suggest that MEG-01-derived EVs approximate certain aspects of megakaryocyte-lineage exosomes and activated platelet-like states, although they do not fully replicate native platelet biology. Notably, plasma exosomes show strong proteomic convergence with MEG-01 exosomes, whereas platelet exosomes retain distinct activation-related features.

Spatial analysis via multiplex immunohistochemistry (mIHC) confirmed the preferential localization of SPP1+ TAMs near ECs in MET. These results suggest a potential communication between TAMs and ECs that contributes to LNM in HNSCC, providing critical insights for HNSCC prognosis and precision treatment.

In summary, the present study provides novel insights into the pharmacological effects of GA. GA as a novel IL1R1 agonist, promotes MK differentiation and platelet formation via downstream pathway of SRC/MEK/ERK, suggesting that GA's potential as a therapeutic candidate for treating RIT.

This study establishes a causal relationship between platelet count and glioma risk through genetic evidence. Increased platelet count confers protection against glioma, including GBM. Suppressed expression of platelet-related genes in glioma cells supports this finding. These results provide new insights into glioma pathogenesis and suggest potential for platelet-based prevention strategies and biomarker development.

In these models, we observed that ifetroban reduces metastasis in the absence of a primary tumor and when TPr is deleted from tumor cells, further supporting the notion that ifetroban attenuates the supportive role of platelet TPr in the metastatic cascade. Based on the results of this study, ifetroban could be pursued as a clinical agent to reduce metastasis in TNBC patients.

A low-dose combination therapy of fostamatinib, Aducanumab, and acetylsalicylic acid (aspirin) may control TEP effects. In conclusion, our preclinical in silico approach revealed FDA-approved drugs that allow therapeutic targeting of metastasis-promoting TEPs and target NSCLC at the same time.

Moreover, betulinic acid exhibited a platelet inhibitory effect on platelet adhesion on collagen-coated surfaces. These studies show that betulinic acid inhibits collagen-induced platelet activation through a reduction in SYK phosphorylation, corroborating the antiplatelet activities of betulinic acid.

Furthermore, we selected specific inhibitors of integrin-αv (cilengitide) and galectin-3 (GB1107) that did not interfere with PLT aggregation itself...Complementary analyses of proteomic datasets from breast cancer tissues demonstrated a significant positive correlation between TGFβ1 and the platelet marker integrin alpha-IIb (ITGA2B; also known as CD41), particularly in luminal A subtypes and in cancers with lymph node involvement. These findings suggest that TGFβ stimulation enhances PLT-breast-cancer cell interactions and promotes PLT aggregation through the upregulation of specific adhesion proteins, thereby potentially contributing to CAT and metastatic progression.

Non-DS-AMKL primarily occurs in children between 1 and 3 years of age. The patients with this disorder have a high incidence rate of chromosomal abnormalities, with complex karyotypes in most patients. Some patients harbor fusion genes or gene mutations. Although the initial remission rate is high, the long-term survival rate remains low.

These findings indicate that impaired MK maturation, and reduced G6B expression lead to the predominance of pro-inflammatory MKs which produce factors that further arrest MK development in MF-MPIG6B and MPN-MF-T patients. NCT03895112.

Patients with AMKL might benefit from induced remission chemotherapy combined with novel targeted therapy. Hematopoietic stem cell transplantation should be carried out as soon as possible after the first CR induced by standard chemotherapy to optimize the prognosis.
