Sir1 establishes transcriptional silencing at the cryptic mating-type loci HMR and HML (HM loci) by recruiting the three other Sir proteins, Sir2, -3, and -4, that function directly in silenced chromatin. However, SIR1-independent mechanisms also contribute to recruiting the Sir2-4 proteins to the HM loci. A screen to elucidate SIR1-independent mechanisms that establish HMR silencing identified...
We studied the effects of 2 different dosages of highmolecular- weight poly-γ-glutamic acid (hm γ-PGA) derived from Bacillus subtilis chungkookjang on lipid metabolism in a high-fructose diet-induced hypertriglyceridemic animal model. For 4 weeks, rats were fed either AIN-93 diet (normal control, NC; n = 10) or modified AIN-93 diet in which cornstarch was substituted with 63% fructose (n = 30) ...
Protein kinase C (PKC) is involved in a wide array of cellular processes such as cell proliferation, differentiation and apoptosis. Phosphorylation of both turn motif (TM) and hydrophobic motif (HM) are important for PKC function. Here, we show that the mammalian target of rapamycin complex 2 (mTORC2) has an important function in phosphorylation of both TM and HM in all conventional PKCs, novel...
UHRF1 is an important epigenetic regulator for maintenance DNA methylation. UHRF1 recognizes hemi-methylated DNA (hm-DNA) and trimethylation of histone H3K9 (H3K9me3), but the regulatory mechanism remains unknown. Here we show that UHRF1 adopts a closed conformation, in which a C-terminal region (Spacer) binds to the tandem Tudor domain (TTD) and inhibits H3K9me3 recognition, whereas the SET-an...
The current study investigated the role of motivation in promoting reading comprehension skills among at-risk first graders. For this purpose, 20 at-risk first graders were recruited to participate in an interactive one-to-one tutoring reading comprehension intervention program. Following the children and tutors motivation level, four sub-groups were created: highly motivated children/ highly m...
On the Birkhoff factorization problem for the Heisenberg magnet and nonlinear Schrödinger equations
A geometrical description of the Heisenberg magnet (HM) equation with classical spins is given in terms of flows on the quotient space G/H+ where G is an infinite dimensional Lie group and H+ is a subgroup of G. It is shown that the HM flows are induced by an action of R2 on G/H+, and that the HM equation can be integrated by solving a Birkhoff factorization problem for G. For the HM flows whic...
Insulin, downstream of Akt activation, promotes glucose uptake into fat and muscle cells to lower postprandial blood glucose, an enforced change in cellular metabolism to maintain glucose homeostasis. This effect is mediated by the Glut4 glucose transporter. Growth factors also enhance glucose uptake to fuel an anabolic metabolism required for tissue growth and repair. This activity is predomin...
background: the sporadic type of hemiplegic migraine (hm) is sometimes observed among migrainous patients (mp) and mimics ischemic strokes. methods: in an evaluation of two-hundred consecutive adult mp in the mackenzie headache clinic, canada during 2004 , 9% of the patients met the criteria established by the international headache society for sporadic hm. female to male sex ratio, family hist...
