Genetic and molecular characterization of the dominant suppressors of D-raf(C110) on the second chromosome identified two gain-of-function alleles of rolled (rl), which encodes a mitogen-activated protein (MAP) kinase in Drosophila. One of the alleles, rl(Su23), was found to bear the same molecular lesion as rl(Sem), which has been reported to be dominant female sterile. However, rl(Su23) and t...
A method for the generation of stable activation tag inserts was developed in Arabidopsis using the maize (Zea mays) En-I transposon system. The method employs greenhouse selectable marker genes that are useful to efficiently generate large populations of insertions. A population of about 8,300 independent stable activation tag inserts has been produced. Greenhouse-based screens for mutants in ...
A novel topology for a high gain two-stage amplifier is proposed. The proposed circuit is designed in a way that the non-dominant pole is at output of the first stage. A positive capacitive feedback (PCF) around the second stage introduces a left half plane (LHP) zero which cancels the phase shift introduced by the non-dominant pole, considerably. The dominant pole is at the output node which m...
Allele-specific silencing of mutant p53 attenuates dominant-negative and gain-of-function activities
Many p53 hotspot mutants not only lose the transcriptional activity, but also show dominant-negative (DN) and oncogenic gain-of-function (GOF) activities. Increasing evidence indicates that knockdown of mutant p53 (mutp53) in cancer cells reduces their aggressive properties, suggesting that survival and proliferation of cancer cells are, at least partially, dependent on the presence of mutp53. ...
Ferroportin mutation in autosomal dominant hemochromatosis: loss of function, gain in understanding.
521 Normal iron homeostasis requires close matching of dietary iron absorption with body iron needs (1). Hereditary hemochromatosis (HH), a common abnormality of iron metabolism, is characterized by excess absorption of dietary iron despite elevated stores, and secondary damage to the liver, pancreas, and other organs (2). Classic HH is caused by mutation of the HFE gene and is inherited as an ...
Aicardi-Goutières Syndrome is caused by IFIH1 mutations Oda et al.(2014) The American Journal of Human Genetics 95(1): 121-125. Gain-of-function mutations in IFIH1 cause a spectrum of human disease phenotypes associated with upregulated type I interferon signaling Rice et al.(2014) Nature Genetics 46(5): 503-510.
Macrothrombocytopenia (MTP) is a heterogeneous group of disorders characterized by enlarged and reduced numbers of circulating platelets, sometimes resulting in abnormal bleeding. In most MTP, this phenotype arises because of altered regulation of platelet formation from megakaryocytes (MKs). We report the identification of DIAPH1, which encodes the Rho-effector diaphanous-related formin 1 (DIA...
