genes p
A relatively recent discovery of structural p53 homologs, the genes p63 and p73, which seem to have more ancient roots, has roused keen interest in their function.
      
Transforming genes (P-ADE7,4and S-LEU2), as linear DNA molecules, can transform competent cells with high efficiency inversely proportional to the molecule size.
      
Nontransforming genes (P-ADE5 and H-LEU2) transform P.
      
This paper investigated the correlation between polymorphisms and haplotypes in the apolipoprotein B (apoB) gene (SP-I/D, Xbal-RFLP, VNTR) and natural longevity persons among the Uygur people in Xinjiang.
      
Antibodies neutralization analysis indicated that four HearNPV oral infection essential genes p74, pif-1, pif-2 and pif-3 are also essential for HearNPV ODV infection in vitro.
      
Potential downstream effectors of NO include the second messenger cyclic GMP, activation of the tumor-suppressor genes p53 and Rb, and the cyclin-dependent kinase inhibitor p21.
      
In almost all pancreas cancers at least one alteration will occur out of a combination of K-ras mutations and inactivation of the tumor suppressor genes p16/MTS1/ink4a, p53 and DPC4/Smad4.
      
Mutations in coding and regulatory regions, as well as aberrantexpression patterns of several oncogenes (c-myc, ras) andtumor suppressor genes (p16, p15) have been reported.
      
The spontaneous mutation rate in the six "chosen" genes p, al, we, w, le and st appeared to lie between 0.8×10-4 and 2.8×10-4.
      
Southern hybridization, using labelled cp genes (P700 and ribulosebiphosphate-carboxylase large subunit), indicated the presence of cpDNA-homologous regions on putative mtDNA fragments.
      
Like Dni, gene sp reduces basal branching, while a branching gene, here resymbolized b, is shown to delay flowering in certain circumstances.
      
Also frequently lost are the cell cycle control genes p16 and p15.
      
The MAdCAM-1 gene was located at p13.3 on chromosome 19, in close proximity to the ICAM-1 and ICAM-3 genes (p13.2-p13.3).
      
Changes in mRNA from the SpC3 gene (Sp064) were also followed by RT-PCR.
      
We determined previously that coelomocytes specifically express the SpC3 gene (Sp064); however, the sea urchin has at least four different types of coelomocytes: amoeboid phagocytes, red spherule cells, colorless spherule cells, and vibratile cells.
      
Seven genes (P2X1-7) have been cloned and the channels form as either homo or heterotrimeric channels giving rise to a wide range of phenotypes.
      
Frequent alterations in the expression of tumor suppressor genes p16INK4A and pRb in esophageal squamous cell carcinoma in the I
      
The purpose of this study was to compare the transcriptional effects of two mutations, nin5 and byp, which map between genes P and Q and allow phage λ to grow in the absence of the N gene product.
      
The tumour suppressor gene p53 and its downstream effector genes p21, mdm-2,and gadd45 seem to be important in the cellular response to genotoxic drug induced damage.
      
The BrassicaS product of the pollen-signalling S-gene (SP11 for Specificity Pollen, or SCR for S locus Cysteine Rich) has recently been identified as a member of the family of PCPs (Pollen Coat Proteins), a group of small basic proteins.
