HDAC inhibitor enhances ferroptosis susceptibility of AML cells by stimulating iron metabolism.

Acute Myeloid Leukemia (AML) are challenging blood cancers with limited long-term survival rates, necessitating novel therapeutic strategies. This study explored the role of Histone deacetylase (HDAC) inhibitors in enhancing ferroptosis in AML cells by modulating iron metabolism. We demonstrated that HDAC inhibitors (Entinostat and Vorinostat) sensitize AML cells to ferroptosis both in vitro and in vivo.

IGF2-IGF1R signaling inhibition delays the growth of IGF2-high colorectal cancer by modulating MDSCs.

Approximately 22 % of human colorectal cancers (CRC) are characterized by IGF2 overexpression, and the tumor-promoting role of IGF2 has been widely reported. Despite promising preclinical results, IGF2 signaling inhibition therapy has exhibited limited efficacy in treating unselected patients with CRC. Recent evidence suggests that IGF2-high CRC are more sensitive to IGF2 signaling blockade therapy in immune-deficient mice, suggesting that IGF2-high CRC can benefit from IGF2 signaling blockade therapy.

The progression rate and risk factor analysis of small gastric subepithelial tumors: a systematic review and meta-analysis.

Background And Aims: Small gastric subepithelial tumors (SETs) in the stomach can be managed through surveillance or resection. However, it is still controversial how often the lesion would progress if left untreated. This study aimed to evaluate the progression rate of small SETs and identify risk factors influencing tumor growth.

Allocentric and egocentric spatial representations coexist in rodent medial entorhinal cortex.

Successful navigation relies on reciprocal transformations between spatial representations in world-centered (allocentric) and self-centered (egocentric) frames of reference. The neural basis of allocentric spatial representations has been extensively investigated with grid, border, and head-direction cells in the medial entorhinal cortex (MEC) forming key components of a 'cognitive map'. Recently, egocentric spatial representations have also been identified in several brain regions, but evidence for the coexistence of neurons encoding spatial variables in each reference frame within MEC is so far lacking.

Here we presented that RUNX1 was upregulated in CC and associated with poor prognosis.

Chitooligosaccharides promote diabetic wound healing by mediating fibroblast proliferation and migration.

Diabetic wounds are notoriously difficult to heal due to impaired cell repair mechanisms, reduced angiogenesis, and a heightened risk of infection. Fibroblasts play a vital role in wound healing by producing extracellular matrix (ECM) components and various growth factors, but their function is inhibited in diabetic wounds. Chitooligosaccharides (COS), intermediate products of chitosan degradation, have shown efficacy in promoting tissue repair, yet their role in diabetic wound healing remains underexplored.
