Dietary fibers (DF) may affect energy balance, an effect often ascribed to the viscous nature of some water soluble DF, which affect luminal viscosity and thus multiple physiological processes. We have tested the hypothesis that viscous linseed DF reduce apparent nutrient digestibility, and limit weight gain, in a randomized feeding trial where 60 male, growing, Wistar rats, with an initial wei...
Squamous metaplasia in airway epithelium is a pathological process arising from abnormal remodeling/repair responses to injury. Proteolytic maturation of many growth and differentiation factors involved in tissue remodeling is controlled by proprotein convertases (PCs). However, the role of these convertases in airway remodeling remains poorly understood. Using a retinoic acid deficiency-induce...
We have previously described a type I transforming growth factor (TGF)-beta receptor (TbetaR-I) polymorphic allele, TbetaR-I(6A), that has a deletion of three alanines from a nine-alanine stretch. We observed a higher than expected number of TbetaR-I(6A) homozygotes among tumor and nontumor DNA from patients with a diagnosis of cancer. To test the hypothesis that TbetaR-I(6A) homozygosity is as...
Substance P (SP) is implicated in stress regulation and affective and anxiety-related behavior. Particularly high expression has been found in the main output region of the amygdala complex, the central amygdala (CE). Here we investigated the cellular mechanisms of SP in CE in vitro, taking advantage of glutamic acid decarboxylase-green fluorescent protein (GAD67-GFP) knockin mice that yield a ...
The genes for cellobiose utilization are normally cryptic in Escherichia coli. The cellobiose system was used as a model to understand the process by which silent genes are maintained in microbial populations. Previously reported was (1) the isolation of a mutant strain that expresses the cellobiose-utilization (Cel) genes and (2) that expression of those genes allows utilization of three beta-...

To find new anti-thrombotic agents, a natural amino acid was introduced into the 3-position of anti-platelet aggregation active 3S-tetrahydroisoquinoline-3-carboxylic acid (THIQA), and 20 novel dipeptide derivatives, 3S-tetrahydroisoquinoline-3-carboxyamino acids (6a-t), targeting the intestinal peptide transport system were provided. In vitro anti-platelet aggregation assay of 6a-t indicated t...
Human herpesvirus 6A (HHV-6A) is a common virus with a worldwide distribution that has been associated with multiple sclerosis. Whether HHV-6A can replicate in dendritic cells (DC) and how the infection might modulate the functional properties of the cell are currently not well known and need further investigations. Here, we show that a non-productive infection of HHV-6A in DC leads to the up-r...
تکنیک هضم آنزیمی dna هترودوپلکس، یکی از متداولترین تکنیک های مورد استفاده در شناسایی جهش های نقطه ای قطعات ژنومی است. در سال های اخیر تحقیقات متعددی در زمینه شناسایی و معرفی آنزیم های اندونوکلئاز جدید با قابلیت هضم اختصاصی با نواحی هترودوپلکس در ملکول های dna انجام شده است، در حال حاضر آنزیم های cel i و cel ii (آنزیم اصلی کیت های تشخیص جهش ترانس ژنومیک) از گیاه کرفس (apium graveolens l.) در این...
Ly-6A is a murine antigen which is implicated in lymphocyte activation and may be involved in activation of hematopoietic stem cells. Antibody cross-linking studies and antisense experiments have suggested that Ly-6A is a lymphocyte coactivation molecule. To better understand the function of Ly-6A, we used gene targeting to produce Ly-6A null mice which are healthy and have normal numbers and p...
