Members of the NF-YB transcription factor gene family play important roles in diverse processes related to plant growth and development, such as seed development, drought tolerance, and flowering time. However, the function of NF-YB genes in cotton remains unclear. A total of 23, 24, and 50 NF-YB genes were identified in Gossypium arboreum (G. arboreum), Gossypium raimondii (G. raimondii), and ...

YB-1 cDNA clones were isolated by binding site screening of a Hela expression library using a human papillomavirus type 18 enhancer oligonucleotide. YB-1 belongs to a family of transcription factors which bind to recognition sequences containing a core CCAAT element. YB-1 bound to its single stranded recognition sequence on the sense strand but not to the anti-sense strand. A synthetic peptide ...

Epithelial-to-mesenchymal transition (EMT) plays an important role in prostate cancer (PCa) metastasis. The transcription/translation regulatory Y-box binding protein-1 (YB-1) is known to be associated with cancer metastasis. We observed that YB-1 expression increased with tumor grade and showed an inverse relationship with E-cadherin in a human PCa tissue array. Forced YB-1 expression induced ...

PURPOSE The Y-box binding protein 1 (YB-1) regulates expression of P-glycoprotein encoded by the MDR1 gene. There have been no previous studies regarding the involvement of YB-1 in the development of resistance to paclitaxel. The present study was done to examine how paclitaxel affects the localization and expression of YB-1 in breast cancer. EXPERIMENTAL DESIGN We evaluated the expression an...

Purpose: Y-box–binding protein-1 (YB-1) is known to conduct various functions related to cell proliferation, anti-apoptosis, epithelial–mesenchymal transition, and castration resistance in prostate cancer. However, it is still unknown how YB-1 affects cancer biology, especially its correlations with the mitogen-activated protein kinase (MAPK) signaling pathway. Therefore, we aimed to examine th...

Darier's disease (DD), caused by mutations in the endoplasmic reticulum (ER) Ca(2+) ATPase ATP2A2 (SERCA2b), is a skin disease that exhibits impaired epidermal cell-to-cell adhesion and altered differentiation. Although previous studies have shown that keratinocyte Ca(2+) sequestration and fluxes are controlled by sphingolipid signaling, the role of this signaling pathway in DD previously has n...

We evaluated the C(6) coefficients of Yb-Yb, Yb-alkali, and Yb-group II van der Waals interactions with 2% uncertainty. The only existing experimental result for such quantities is for the Yb-Yb dimer. Our value, C(6)=1929(39) a.u., is in excellent agreement with the recent experimental determination of 1932(35) a.u. We have also developed a new approach for the calculation of the dynamic corre...

Signal Transducers and Activators of Transcription (STATs) are transcription factors which lie at the end of cytokine and growth signal transduction pathways. Dictyostelium Dd-STATa is a functional homologue of metazoan STATs. It is activated by cAMP and, at the slug stage, it translocates into the nuclei of the tip cells, which are a subset of the anterior, prestalk A (pstA) cells. Here we sea...

Core-shell-structured nanoalloy particles with an Al-dominated interior covered by few Yb monolayers have been fabricated using a vapor-aggregation method involving magnetron sputtering. The radially segregated structure of the Yb-Al nanoparticles has been disclosed by "on-the-fly" photoelectron spectroscopy monitoring of the nanoparticle beam in Yb 4f and Al 2p electron binding energy regions....
