The alignment of the left-right (LR) body axis relative to the anteroposterior (AP) and dorsoventral (DV) axes is central to the organization of the vertebrate body plan and is controlled by the node/organizer. Somitogenesis plays a key role in embryo morphogenesis as a principal component of AP elongation. How morphogenesis is coupled to axis specification(More)
Patterning of the primitive foregut promotes appropriate organ specification along its anterior-posterior axis. However, the molecular pathways specifying foregut endoderm progenitors are poorly understood. We show here that Wnt2/2b signaling is required to specify lung endoderm progenitors within the anterior foregut. Embryos lacking Wnt2/2b expression(More)
The embryonal long terminal repeat-binding protein, ELP, is present in undifferentiated mouse embryonal carcinoma cells. It binds to and suppresses transcription of the Moloney leukemia virus long terminal repeat in undifferentiated murine embryonal carcinoma cells. We report here that ELP is a mouse homolog of Drosophila FTZ-F1, which positively regulates(More)
The ubiquitin-proteasome system has a crucial role in maintaining and regulating cellular homeostasis including carcinogenesis. UBE2Q2, also designated Ubci, is one of the ubiquitin-conjugating enzymes (E2), and it has been reported that mRNA of UBE2Q2 is highly expressed in human head and neck squamous cell carcinoma, particularly hypopharyngeal carcinoma.(More)
Regulation of transcription elongation by RNA polymerase II (Pol II) is a key regulatory step in gene transcription. Recently, the little elongation complex (LEC)-which contains the transcription elongation factor ELL/EAF-was found to be required for the transcription of Pol II-dependent small nuclear RNA (snRNA) genes. Here we show that the human Mediator(More)
Protein kinase C (PKC), which comprises 11 closely related isoforms, has been implicated in a wide variety of cellular processes, such as growth, differentiation, secretion, apoptosis and tumour development. Among the PKC isotypes, PKC-delta is unique in that its overexpression results in inhibition of cell growth. Here we show that mice that lack PKC-delta(More)
Ataxia-telangiectasia (AT) is an autosomal recessive genetic disease characterized by immunological deficiencies, neurological degeneration, developmental abnormalities and an increased risk of cancer. Ataxia-telangiectasia group D (ATDC) was initially described as a gene related to AT. Ataxia-telangiectasia group D, also known as TRIM29, is structurally a(More)
The androgen receptor (AR) is a ligand-dependent transcription factor that belongs to the family of nuclear receptors, and its activity is regulated by numerous AR coregulators. AR plays an important role in prostate development and cancer. In this study, we found that TRIM24/transcriptional intermediary factor 1alpha (TIF1alpha), which is known as a(More)
Electrical potentials within the thalamus associated with the endogenous late positive component (LPC or P300) of cerebral evoked potentials were investigated in humans and cats. Essentially identical discrimination tasks using classical aversive conditioning were employed for recording LPC in both species. In humans, a negative wave within the same latency(More)
The transcription factor nuclear factor-kappaB (NF-kappaB) plays roles in apoptosis, inflammation and oncogenesis. It is important for biological and medical research to understand when proteins of interest are activated in cells, leading to the establishment of a luciferase/EGFP assay to monitor the activation of transcription factors. Here, we describe an(More)
