TL;DR: A switching state-space model was applied to 135 Argos satellite tracks to account for observation error, and to distinguish between migratory and area-restricted search behaviors of leatherback turtles as discussed by the authors.
Abstract: Interactions with fisheries are believed to be a major cause of mortality for adult leatherback turtles (Dermochelys coriacea), which is of particular concern in the Pacific Ocean, where they have been rapidly declining. In order to identify where these interactions are occurring and how they may be reduced, it is essential first to understand the movements and behavior of leatherback turtles. There are two regional nesting populations in the East Pacific (EP) and West Pacific (WP), comprising multiple nesting sites. We synthesized tracking data from the two populations and compared their movement patterns. A switching state-space model was applied to 135 Argos satellite tracks to account for observation error, and to distinguish between migratory and area-restricted search behaviors. The tracking data, from the largest leatherback data set ever assembled, indicated that there was a high degree of spatial segregation between EP and WP leatherbacks. Area-restricted search behavior mainly occurred in the southeast Pacific for the EP leatherbacks, whereas the WP leatherbacks had several different search areas in the California Current, central North Pacific, South China Sea, off eastern Indonesia, and off southeastern Australia. We also extracted remotely sensed oceanographic data and applied a generalized linear mixed model to determine if leatherbacks exhibited different behavior in relation to environmental variables. For the WP population, the probability of area-restricted search behavior was positively correlated with chlorophyll-a concentration. This response was less strong in the EP population, but these turtles had a higher probability of search behavior where there was greater Ekman upwelling, which may increase the transport of nutrients and consequently prey availability. These divergent responses to oceanographic conditions have implications for leatherback vulnerability to fisheries interactions and to the effects of climate change. The occurrence of leatherback turtles within both coastal and pelagic areas means they have a high risk of exposure to many different fisheries, which may be very distant from their nesting sites. The EP leatherbacks have more limited foraging grounds than the WP leatherbacks, which could make them more susceptible to any temperature or prey changes that occur in response to climate change.

TL;DR: The contiguous genomic sequence of the 3′ part of the Igha locus allows a detailed view of the recent evolution of this highly dynamic locus in the mouse.
Abstract: Although the entire mouse genome has been sequenced, there remain challenges concerning the elucidation of particular complex and polymorphic genomic loci. In the murine Igh locus, different haplotypes exist in different inbred mouse strains. For example, the Ighb haplotype sequence of the Mouse Genome Project strain C57BL/6 differs considerably from the Igha haplotype of BALB/c, which has been widely used in the analyses of Ab responses. We have sequenced and annotated the 3′ half of the Igha locus of 129S1/SvImJ, covering the CH region and approximately half of the VH region. This sequence comprises 128 VH genes, of which 49 are judged to be functional. The comparison of the Igha sequence with the homologous Ighb region from C57BL/6 revealed two major expansions in the germline repertoire of Igha. In addition, we found smaller haplotype-specific differences like the duplication of five VH genes in the Igha locus. We generated a VH allele table by comparing the individual VH genes of both haplotypes. Surprisingly, the number and position of DH genes in the 129S1 strain differs not only from the sequence of C57BL/6 but also from the map published for BALB/c. Taken together, the contiguous genomic sequence of the 3′ part of the Igha locus allows a detailed view of the recent evolution of this highly dynamic locus in the mouse.

TL;DR: The observations suggest that LRP-1 may be involved in normal and malignant signal transduction through a direct interaction with Shc adaptor proteins.
Abstract: We recently observed that the LDL receptor-related protein 1 (LRP-1) is tyrosine phosphorylated in v-Src-transformed cells. Using a GST-fusion protein containing the cytoplasmic domain of LRP-1, we show that LRP-1 is a direct substrate for v-Src in vitro. To study LRP-1 phosphorylation in vivo, we constructed an LRP-1 minireceptor composed of the beta chain linked at the amino-terminus to a Myc epitope (Myc-LRPbeta). When expressed together with v-Src, Myc-LRPbeta becomes phosphorylated on tyrosine. Of the four tyrosine residues present in the cytoplasmic domain of LRP-1, only Tyr 63 is phosphorylated by v-Src in vivo or in vitro. Using fibroblasts deficient in Src, Yes and Fyn, we were able to show that there are multiple kinases present in the cell that can phosphorylate LRP-1. Tyrosine-phosphorylated LRP-1 associates with Shc, a PTB and SH2 domain containing signaling protein that is involved in the activation of Ras. Binding of the purified Shc PTB domain to Tyr 63 containing peptides shows that the interaction between LRP-1 and Shc is direct. We found that DAB, a PTB domain containing signaling protein that is involved in signaling by LDL receptor-related proteins in the nervous system, did not bind to full-length LRP-1. Our observations suggest that LRP-1 may be involved in normal and malignant signal transduction through a direct interaction with Shc adaptor proteins.
