background: induced pluripotent stem cells (ipscs) can be obtained from autologous cells for therapeutic purposes. so, far, many studies have been done to produce induced pluripotent cells by transferring specific pluripotency genes using different methods. in this study, pluripotency gene expression induced by external stresses was assessed in cord blood mononuclear cells. methods: in this exp...
There are two waves of erythropoiesis, known as primitive and definitive waves in mammals and lower vertebrates including zebrafish. The founding member of the Kruppel-like factor (KLF) family of CACCC-box binding proteins, EKLF/Klf1, is essential for definitive erythropoiesis in mammals but only plays a minor role in primitive erythropoiesis. Morpholino knockdown experiments have shown a role ...
AIMS Krüppel-like factor 4 (KLF4) is implicated in all-trans retinoic acid (ATRA)-induced and platelet-derived growth factor-BB (PDGF-BB)-repressed SM22α expression in vascular smooth muscle cells (VSMCs). However, its exact mechanism of action remains unclear. We determined how KLF4 plays different roles in ATRA- and PDGF-BB-dependent regulation of the SM22α gene. METHODS AND RESULTS ATRA an...
Krüppel-like factor 4 (KLF4) is a transcription factor that can have divergent functions in different malignancies. The expression and role of KLF4 in renal cell cancer remain unclear. The purpose of this study is to determine epigenetic alterations and possible roles of KLF4 in renal cell carcinoma. The KLF4 expression in primary renal cell cancer tissues and case-matched normal renal tissues ...
There is clear evidence that the phenotypic modulation of smooth muscle cells (SMCs) contributes to the pathophysiology of vascular disease. Phenotypic modulation refers to the unique ability of SMCs to alter their phenotype in response to extracellular stimuli and is hallmarked by the loss of SMC marker gene expression. The transcription factor Krüppel-like factor 4 (KLF4) is a known powerful ...
KLF4/GLKF4 is a transcription factor that can have divergent functions in different malignancies. The role of KLF4 in prostate cancer etiology remains unclear. We have recently reported that small double-stranded RNA can induce gene expression by targeting promoter sequence in a phenomenon referred to as RNA activation (RNAa). In this study, we examine KLF4 levels in prostate cancer tissue and ...
Ovarian cancer presents therapeutic challenges due to its typically late detection, aggressive metastasis, and therapeutic resistance. The transcription factor Krüppel-like factor 4 (KLF4) has been implicated in human cancers as a tumor suppressor or oncogene, although its role depends greatly on the cellular context. The role of KLF4 in ovarian cancer has not been elucidated in mechanistic det...
Stem cell – like tumor propagating cells self-renew to drive clonal expansion or differentiate into post-mitotic without tumorigenic potential in squamous carcinomas. This fate choice is governed by a transcriptional network comprised of SOX2-PITX1-TP63 driven self-renewal and KLF4 dependent differentiation circuits. Yet, how stem switch from remains elusive. Here, we report that this bi-stable...
Krüppel-like factor 4 (KLF4), a transcription factor involved in both tumor suppression and oncogenesis in various human tumors, is subject to alternative splicing that produces KLF4α. KLF4α is primarily expressed in the cytoplasm because it lacks exon 3 of KLF4, which contains the nuclear localization signal. The role of KLF4 in breast cancer remains unclear and nothing is known yet about the ...
Krüppel-like factor 4 (KLF4) is a transcription factor and functions as a tumor suppressor or tumor promoter in different cancer types. KLF4 regulates many gene expression, thus affects the process of cell proliferation, differentiation, and apoptosis. Recently, KLF4 was reported to induce senescence during the generation of induced pluripotent stem (iPS) cells, but the exact mechanism is still...
