Aim: To evaluate the relationship between vascular endothelial growth factor (VEGF), p53, and the H-ras oncogene and different clinicopathological parameters in Egyptian patients with Schistosoma-associated transitional cell carcinoma of the bladder.
Methods: The study included 50 patients with transitional cell carcinoma for whom radical cystectomy and urinary diversions were carried out. VEGF and p53 protein expressions were evaluated with an immunohistochemical staining method, and H-ras oncogene mutations were analyzed with a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.
Results: High grade tumors revealed higher p53 immunostaining than low grade tumors (P = 0.016). p53 and VEGF protein expressions, as well as H-ras oncogene mutations, had an insignificant impact on patient outcomes (P = 0.962, P = 0.791, and P = 967, respectively). Cancer extension to regional lymph nodes was associated with poor outcomes (P = 0.008).
Conclusion: VEGF, p53 and the H-ras oncogene have no relation to patient survival and outcome in Schistosoma-associated transitional cell carcinoma.

Background: There is still no reliable therapeutic targets and effective pharmacotherapy for metabolic dysfunction-associated steatotic liver disease (MASLD). RASD1 is short for Ras-related dexamethasone-induced 1, a pivotal factor in various metabolism processes of Human. However, the role of RASD1 remains poorly illustrated in MASLD.

SIGLEC9 (sialic acid-binding Ig-like lectin 9) is a molecule thought to have a significant influence on the immune properties of the colorectal cancer (CRC) tumor microenvironment (TME). In our study, we assessed the expression of the SIGLEC9 protein in CRC tissue and the surgical margin tissue. Using RT-PCR, we analyzed mutations in the KRAS, NRAS, BRAF, PIK3CA, and AKT genes.

Introduction: Back pain (BP) is a complex heritable trait with an estimated heritability of 40% to 60%. Less than half of this can be explained by known genetic variants identified in genome-wide association studies.
Objectives: We applied a powerful multi-trait and gene-based approach to association analysis of BP to identify novel genes associated with BP.

Juxtaglomerular cell tumor (JxGCT) is a rare type of renal neoplasm demonstrating morphologic overlap with some mesenchymal tumors such as glomus tumor (GT) and solitary fibrous tumor (SFT). Its oncogenic drivers remain elusive, and only a few cases have been analyzed with modern molecular techniques. In prior studies, loss of chromosomes 9 and 11 appeared to be recurrent.

Unlabelled: The RASopathies are a group of disorders resulting from a germline variant in the genes encoding the Ras/mitogen-activated protein kinase pathway. These disorders include Noonan syndrome (NS), cardiofaciocutaneous syndrome (CFC), Costello syndrome (CS), Legius syndrome (LS), and neurofibromatosis type 1 (NF1), and have overlapping clinical features due to RAS/MAPK dysfunction. In this study, we aimed to describe the clinical and molecular features of patients exhibiting phenotypic manifestations consistent with RASopathies.
