runx3, a member of runt-related transcription factor (runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. in the present study, exogenous run3 was transiently expressed in ags (human gastric adenocarcinoma), with undetectable runx3 protein and in a549 (human lung carc...

Runt-related transcription factor 3 (RUNX3) has been reported as a tumor suppressor in some kinds of cancers. In the present study, hepatocellular carcinoma (HCC) microarray analysis showed that RUNX3 expression was significantly lower in HCC tissues compared with that in adjacent non-tumor tissues, and was negatively associated with metastasis and TNM stage. RUNX3 was an independently prognost...

Runx3, a member of Runt-related transcription factor (Runx) proteins with tumor suppressor effect, is a tissue-restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. In the present study, exogenous Run3 was transiently expressed in AGS (human gastric adenocarcinoma), with undetectable Runx3 protein and in A549 (human lung carc...

We previously demonstrated that the Runx3 transcription factor is expressed in the hypothalami, pituitaries, and ovaries of mice, and that Runx3 knockout (Runx3-/-) mice are anovulatory and their uteri are atrophic. Runx3 mRNA expression was detected in the granulosa cells of ovarian follicles, and in the anteroventral periventricular nucleus (AVPV) and arcuate nucleus (ARC). In the present stu...

the high CISs found only in the PLX4720-resistant tumors. Further characterization revealed four transposon sites in the first intron of ERAS, with an integration pattern signifying gene activation. The PLX4720-resistance conferring phenotype was confirmed in human melanoma cell lines ectopically expressing ERas. Further mechanistic studies revealed that ERAS inactivation of BAD (BCL2-associate...

Regulation of gene expression by tissue-specific transcription factors involves both turning on and turning off transcription of target genes. Runx3, a runt-domain transcription factor, regulates cell-intrinsic functions by activating and repressing gene expression in sensory neurons, dendritic cells (DC), and T cells. To investigate the mechanism of Runx3-mediated repression in an in vivo cont...

BACKGROUND We have recently shown that expression of the cell adhesion molecule E-cadherin is required for LIF-dependent pluripotency of mouse embryonic stem (ES) cells. METHODOLOGY In this study, we have assessed global transcript expression in E-cadherin null (Ecad-/-) ES cells cultured in either the presence or absence of LIF and compared these to the parental cell line wtD3. RESULTS We ...

Runx3 is a transcription factor that belongs to the Runx family. We studied the localization of Runx3 mRNA in the mouse uterus, and its function in the mouse endometrium using Runx3 knockout (Runx3(-/-)) mice. Runx3 mRNA was detected in the endometrial luminal epithelial cells, glandular epithelial cells and stromal cells below the epithelial cell layer on the luminal side. The uteri of Runx3(-...

Purposes SMAD4/DPC4 mutations have been associated with aggressive behavior in pancreatic ductal adenocarcinomas (PDAC), and it has recently been suggested that RUNX3 expression combined with SMAD4 status may predict the metastatic potential of PDACs. We evaluated the prognostic utility of SMAD4/RUNX3 status in human PDACs by immunohistochemistry. Materials and Methods Immunohistochemical sta...

We investigated the clinical significance of RUNX3 gene expression in human pancreatic carcinoma. Five samples of pancreatic tissues and 30 samples of pancreatic cancer tissues and paracancerous tissues were collected. RUNX3 expression was detected by real-time PCR and immunohistochemistry. The relationships between clinicopathological findings and the expression of RUNX3 were analyzed. The rel...
