Down-Regulation of EPAS1 Transcription and Genetic Adaptation of Tibetans to High-Altitude Hypoxia

Molecular biology and evolution, 2017
Tibetans are well adapted to the hypoxic environments at high altitude, yet the molecular mechanism of this adaptation remains elusive. We reported comprehensive genetic and functional analyses of EPAS1, a gene encoding hypoxia inducible factor 2α (HIF ...

N-myc Down-Regulates Activin A

Biochemical and Biophysical Research Communications, 2000
N-myc oncogene amplification is frequent in human neuroblastoma and predicts poor prognosis, but the molecular consequences have remained obscure. We report here that enhanced N-myc expression correlates with low or undetectable expression of activin A, but not other closely related members of the transforming growth factor-beta superfamily.

The effect of cognitive reappraisal and expression suppression on sadness and the recognition of sad scenes: An event-related potential study

Frontiers in Psychology, 2022
Previous studies have found differences in the cognitive and neural mechanisms between cognitive reappraisal and expression suppression in the regulation of various negative emotions and the recognition of regulated stimuli.

Down-Regulation of Cough during Exercise Is Less Frequent in Healthy Children than Adults. Role of the Development and/or Atopy?

Frontiers in Physiology, 2017
Cough is typically associated with physical activity in children with asthma, but the characteristics of the relationship between cough and exercise has not been established under physiological conditions.

Tollip-induced down-regulation of MARCH1

Results in Immunology, 2013
In addition to their classical antigen presenting functions, MHC class II molecules potentiate the TLR-triggered production of pro-inflammatory cytokines. Here, we have addressed the effect of Tollip and MARCH1 on the regulation of MHC II trafficking and TLR signaling.

Monoterpene regulation of Ras and Ras-related protein expression

Journal of Lipid Research, 2003
Monoterpenes, derived primarily from plants, are products of the isoprenoid biosynthetic pathway and function as chemical messengers with diverse functions. The biochemical bases for these activities are largely undefined.

Role of Arbuscular Mycorrhizal Fungi in Plant Growth Regulation: Implications in Abiotic Stress Tolerance

Frontiers in Plant Science, 2019
Abiotic stresses hamper plant growth and productivity. Climate change and agricultural malpractices like excessive use of fertilizers and pesticides have aggravated the effects of abiotic stresses on crop productivity and degraded the ecosystem. There is

Optimal Down Regulation of mRNA Translation

Scientific Reports, 2017
AbstractDown regulation of mRNA translation is an important problem in various bio-medical domains ranging from developing effective medicines for tumors and for viral diseases to developing attenuated virus strains that can be used for vaccination. Here, we study the problem of down regulation of mRNA translation using a mathematical model called the ...
