Article Synopsis
  • * Significant downregulation of SIRT2-7 was observed in MDS patients, but some genes, like SIRT4, showed increased expression in patients aged 60+, while SIRT2 and SIRT3 were upregulated in those with severe anemia and chromosomal abnormalities.
  • * The study highlights the potential significance of SIRTs in MDS development and progression, suggesting they could be important therapeutic targets and offering avenues for future research focused on managing

Article Synopsis
  • EGFL7 is a significant gene linked to angiogenesis and cancer growth, particularly in colorectal cancer (CRC), prompting research into its role and potential as a therapeutic target.
  • A study involving 463 CRC patients assessed EGFL7 expression through immunohistochemistry and found that 77.7% had low EGFL7 levels, correlating with increased lymph node spread and vessel invasion but no direct impact on overall survival.
  • In silico analysis identified associations between low EGFL7 expression and higher levels of VEGFR2, along with involvement in critical pathways like VEGF, Rap-1, MAPK, and PI3K/Akt, suggesting that EGFL7 could influence tumor invasiveness and recurrence risk.

Angiogenesis is considered one of the hallmarks of cancer, assisting tumor progression and metastasis. The mesoionic compound, MI-D, can induce cell death and provoke cytoskeletal and metabolic changes in cancer cells. Using in vitro and in vivo models, this study aimed to evaluate the effects of MI-D on the viability of human endothelial cells (EC) and its ability to inhibit tumor-induced angiogenesis induced by tumoral cells.

EGFL7 is a proangiogenic factor. It has been widely described with having a vital role in tubulogenesis and regulation of angiogenesis, mainly during embryogenesis and organogenesis. It has been mainly associated with NOTCH pathway, but there are reports showing association with MAPK and integrin pathways.

The aim of this study was to evaluate the expression of , , , and genes in Myelodysplastic neoplasm (MDS) to identify possible targets of ubiquitination and deubiquitination in MDS pathobiology. To achieve this, eight datasets from the Gene Expression Omnibus (GEO) database were integrated, and the expression relationship of these genes was analyzed in 1092 MDS patients and healthy controls. Our results showed that , , and were upregulated in MDS patients compared with healthy individuals, but only in mononucleated cells collected from bone marrow samples ( < 0.

Differentially expressed genes (DEGs) biomarkers can be used to help diagnose and monitor the disease, as well as to determine which treatments are most effective. So, given the complexity of Myelodysplastic neoplasm (MDS), it is difficult to determine the impact and disparities of DEGs between CD34 HSC (hematopoietic stem cells) or primary bone marrow cells (PBMC) in MDS pathogenesis, and therefore it remains largely unknown. Here, we performed an in-silico transcriptome analysis on CD34 HSC and PBMC from 1092 MDS patients analyzing the divergences between differential gene expression patterns in these two cell types as potential pathogenic biomarkers for MDS.

The sirtuins () gene family ( to ) contains the targets implicated in cellular and organismal aging. The role of SIRTs expression in the pathogenesis and overall survival of patients diagnosed with solid tumors has been widely discussed. However, studies that seek to explain the role of these pathways in the hematopoietic aging process and the consequences of their instability in the pathogenesis of different onco-hematological diseases are still scarce.

Background: Despite the advances in glioblastoma (GBM) treatment, the average life span of patients is 14 months. Therefore, it is urgent to identity biomarkers of prognosis, treatment response, or development of novel treatment strategies. We previously described the association of high epidermal growth factor-like domain multiple 7 (EGFL7) expression and unfavorable outcome of pilocytic astrocytoma patients.
