Analysis of osteopontin in mouse growth plate cartilage by application of laser capture microdissection and RT-PCR.

Gene expression of osteopontin (OPN) has been investigated in mice by application of laser capture microdissection (LCM) and reverse transcriptase-polymerase chain reaction (RT-PCR) analysis. LCM permits individual cells to be isolated ("captured")…

Bcl-2 positively regulates Sox9-dependent chondrocyte gene expression by suppressing the MEK-ERK1/2 signaling pathway.

Changes in BiP (GRP78) levels upon HSV-1 infection are strain dependent.

BiP (grp78) is a chaperone protein which can also regulate the unfolded protein response of the cell. Levels of BiP increased in cells infected by the small plaque producing, cell associated, neuroinvasive strains of HSV-1 (SP7, 490) but decreased in…

Developmental pyrethroid exposure causes long-term decreases of neuronal sodium channel expression.

Pyrethroid insecticide use has increased over recent years because of their low to moderate acute toxicity in mammals. However, there is increasing concern over the potential detrimental effects of pyrethroids on developing animals. Most recently, we…

Expression of alpha-cardiac myosin heavy chain in normal and denervated rat muscle spindles.

Whether any fibers in rat hindlimb muscles express alpha-cardiac myosin heavy chain (MHC) is uncertain. Expression of alpha-cardiac MHC mRNA and the polypeptide for which it codes were examined in control and denervated rat muscle spindles using in…

Glucose stimulates cholesterol 7alpha-hydroxylase gene transcription in human hepatocytes.

Bile acids play important roles in the regulation of lipid, glucose, and energy homeostasis. Recent studies suggest that glucose regulates gene transcription in the liver. The aim of this study was to investigate the potential role of glucose in…

Inhibition of cartilage degradation and suppression of PGE2 and MMPs expression by pomegranate fruit extract in a model of posttraumatic osteoarthritis.

OBJECTIVE: Osteoarthritis (OA) is characterized by cartilage degradation in the affected joints. Pomegranate fruit extract (PFE) inhibits cartilage degradation in vitro. The aim of this study was to determine whether oral consumption of PFE inhibits…

Sensory nerves and neuropeptides in uterine cervical ripening.

At the time of parturition (fetal delivery) the uterine cervix must "ripen," becoming soft, pliable, and dilated to accommodate the fetus' delivery. The fundamental processes underlying cervical ripening remain poorly understood. Knowledge that…

The effects of pregnancy and estrogen on the expression of calcitonin gene-related peptide (CGRP) in the uterine cervix, dorsal root ganglia and spinal cord.

Before parturition the uterine cervix undergoes a ripening process ("softens" and dilates) to allow passage of the fetus at term. The exact mechanism(s) responsible for cervical ripening are unknown, though a role for peptidergic sensory neurons is…

The glycoprotein GPNMB attenuates astrocyte inflammatory responses through the CD44 receptor.

BACKGROUND: Neuroinflammation is one of the hallmarks of neurodegenerative diseases, such as Parkinson's disease (PD). Activation of glial cells, including microglia and astrocytes, is a characteristic of the inflammatory response. Glycoprotein…

Valproate increases dopamine transporter expression through histone acetylation and enhanced promoter binding of Nurr1.
