Neural hyperplasia induced by RNA interference with m4/mα gene activity
(2000)The E(spl) complex (E(spl)-C) contains three different classes of genes that are downstream of Notch signaling. The bHLH genes mediate the Notch signal by repressing proneural gene activity, for example during the ...

Neural network controlling feeding in Lymnaea stagnalis: Immunocytochemical localization of myomodulin, small cardioactive peptide, buccalin, and FMRFamide‐ related peptides
(1994)This paper investigates the distribution of four classes of neuropeptides, myomodulin, small cardioactive peptide (SCP), buccalin, and FMRFamide, in central neurons forming the network that underlies feeding behavior in ...

Neuralized Encodes a Peripheral Membrane Protein Involved in Delta Signaling and Endocytosis
(2001)Activation of the Notch (N) receptor involves an intracellular proteolytic step triggered by shedding of the extracellular N domain (N-EC) upon ligand interaction. The ligand Dl has been proposed to effect this N-EC shedding ...

New amino acid polymorphism, Ala/Val4058, in exon 45 of the polycystic kidney disease 1 gene: Evolution of alleles
(1997)The PKD1 gene, which is responsible for the most common form of autosomal dominant polycystic kidney disease, has recently been cloned and sequenced. Many disease-causing mutations have been characterized in this gene, ...

New Insights for Ets2 Function in Trophoblast using Lentivirus-Mediated Gene Knockdown in Trophoblast Stem Cells
(2010)Mouse trophoblast stem (TS) cells represent a unique in vitro system that provides an unlimited supply of TS cells for the study of trophoblast differentiation and TS cell self-renewal. Although the mouse transcription ...

New miRNA profiles accurately distinguish renal cell carcinomas and upper tract urothelial carcinomas from the normal kidney
(2014)Background: Upper tract urothelial carcinomas (UT-UC) can invade the pelvicalyceal system making differential diagnosis of the various histologically distinct renal cell carcinoma (RCC) subtypes and UT-UC, difficult. Correct ...

New phenotypic aspects of the decidual spiral artery wall during early post-implantation mouse pregnancy
(2011)During pregnancy the walls of decidual spiral arteries (SAs) undergo clinically important structural modifications crucial for embryo survival/growth and maternal health. However, the mechanisms of SA remodeling (SAR) are ...

Nitrogen mustard up-regulates Bcl-2 and GSH and increases NTP and PCr in HT-29 colon cancer cells
(1998)We hypothesized that unexplained increases in nucleoside triphosphates (NTP) observed by 31P magnetic resonance spectroscopy (MRS) after treatment of tumours by DNA-damaging agents were related to chemotherapy-induced ...
