The worldwide epidemic of obesity has increased the urgency to develop a deeper understanding of physiological systems related to energy balance and energy storage, including the mechanisms controlling the development of fat cells (adipocytes). The differentiation of committed preadipocytes to adipocytes is controlled by PPARgamma and several other(More)
Defects in cilia are associated with several human disorders, including Kartagener syndrome, polycystic kidney disease, nephronophthisis and hydrocephalus. We proposed that the pleiotropic phenotype of Bardet-Biedl syndrome (BBS), which encompasses retinal degeneration, truncal obesity, renal and limb malformations and developmental delay, is due to(More)
To investigate the factors related to allogenic brain graft rejection, rat cortex from either LEW-RT1l or BN-RT1n rats was transplanted into brains of several isogenic and allogenic inbred strains: F344-RT1l, LEW-RT1l, BN-RT1n, AO-RT1u, PVG-RT1c, PVG-RT1u, and PVG-RT1l. Each donor and host combination was subsequently subdivided into two subgroups. One(More)
In vitro growth properties of three CNS-derived cell lines were compared under a variety of culture conditions. The M213-20 and J30a cell lines were each derived from embryonic CNS culture with the temperature-sensitive (ts) allele of SV40 large T antigen, tsA58, while the A7 cell line was immortalized using wild-type SV40 large T antigen. Cells(More)
The detection of odorants with high sensitivity and specificity utilizes specialized transduction proteins that may be assembled into complexes to afford enhanced speed and efficiency in olfactory neurons. We have used a differential cDNA screening technique to identify novel gene products that display restricted expression within the olfactory epithelium.(More)
Odorant-evoked activity contributes to olfactory epithelium organization and axon targeting. We examined the consequences on gene expression of a genetic disruption of the channel responsible for olfactory transduction. Genes encoding calcium-binding EF-hand motifs, were among the most highly regulated transcripts consistent with the central role of Ca(2+)(More)
Retroviral infection has been proposed as an etiologic factor in schizophrenia. In an effort to unmask a latent retrovirus, short term cultures of peripheral lymphocytes from 15 schizophrenic subjects and nine normal controls were exposed to ionizing radiation and co-cultured with indicator cells. Reverse transcriptase activity, a marker of retroviral(More)
Body fluids such as urine potentially contain a wealth of information pertaining to age, sex, social and reproductive status, physiologic state, and genotype of the donor. To explore whether urine could encode information regarding environment, physiology, and development, we compared the volatile compositions of mouse urine using solid-phase(More)
Genomic clones corresponding to five distinct major histocompatibility complex class II alpha-chains have been described for the rabbit; four of these encode complete, potentially functional alpha-chains. Hybridization analysis and preliminary sequence analysis indicate that one of these clones is structurally related to HLA-DP alpha, one to -DR alpha, one(More)
The rabbit major histocompatibili ty complex (MHC) can be divided into two regions, RLA-A and RLA-D, by serologic and functional assays (Tissot and Cohen 1972, Lancki et al. 1979). The class I genes, encoded in the RLAA region, control allograft rejection and are considered equivalent to HLA-A, -B, and -C and H-2K, H-2D, and H-2L. Genes located in the RLA-D(More)
