Background: Dysregulation of WNT signaling has been reported in many malignancies. Objective: This study was conducted to investigate the expression pattern of 14 members of the WNT gene family in different immunophenotypic subtypes of ALL. Methods: Semi-quantitative RT-PCR was performed on samples from 71 ALL patients and 36 age-matched healthy individuals. The ALL patients were categorized in...

The Wnt-5a gene encodes a secreted protein that controls several normal processes during embryogenesis and development of adult tissues by as yet unknown mechanisms. Endogenous expression of Wnt-5a mRNA is known to occur in both mouse and human mammary cell lines. To investigate the biological role of Wnt-5a in the human mammary epithelial cell line HB2, we used an antisense approach to repress...

Many studies indicate the involvement of WNT signaling in oncogenesis and melanoma drug resistance. Receptor-interacting protein kinase (RIPK4), which targets multiple pathways such as Wnt/β-catenin, NFKB MAPK, is might be a alternative target. This supported by fact that RIPK4 levels are elevated cells compared to normal melanocytes. Since role this regulation pathway remain unknown, we tested...

Wnt-4 (wingless mouse mammary tumor virus integration site-4) protein is involved in many crucial embryonic pathways regulating essential processes. Aberrant Wnt-4 activity causes various anomalies leading to gastric, colon, or breast cancer. Wnt-4 is a conserved protein in structure and sequence. All Wnt proteins contain an unusual fold comprising of a thumb (or N-terminal domain) and index fi...

background: wnt molecules play a key role in growth, proliferation and development of some embryonic and adult organs as well as hematopoietic stem cells. wnt signaling pathways are aberrantly activated in many tumor types, including solid tumors and hematologic malignancies. objective: to investigate the expression profile of a large number of wnt genes in leukemic cells from iranian patients ...

Abnormal inactivation of the Wnt/β-catenin signaling pathway is involved in skin diseases like androgenetic alopecia, vitiligo and canities, but small-molecule activators are rarely described. In this study, we investigated stimulatory effects escin on canonical cultured human dermal papilla cells (hDPCs). Escin stimulated signaling, resulting increased β-catenin lymphoid enhancer-binding facto...

Hyperbaric oxygen therapy promoted brain cell proliferation. Wnt-3 is closely associated with the proliferation of neural stem cells. We examined whether hyperbaric oxygen promoted neural stem cells to proliferate and its correlation with Wnt-3 protein in hypoxic-ischemic neonate rats. Hyperbaric oxygen therapy was administered 3 h after hypoxia ischemia daily for 7 days. The proliferating stem...

The canonical Wnt signaling pathway is of paramount importance in development and disease. An emergent question is whether the upstream cascade of the canonical Wnt pathway has physiologically relevant roles beyond β-catenin-mediated transcription, which is difficult to study due to the pervasive role of this protein. Here, we show that transcriptionally silent spermatozoa respond to Wnt signal...

Abstract Background Medulloblastoma (MB) is a heterogeneous disease, displaying distinct genetic profiles with specific molecular subgroups. This study aimed to validate MB subgrouping using surrogate immunohistochemistry and associate subgroups, histopathological types, available clinicopathological parameters overall survival (OS) progression-free (PFS) of patients. included 40 MBs; immunohis...
