Altruism and social rewards
Scheggia et al.1 have established a behavioral paradigm to explore preferences for ‘altruistic’ or ‘selfish’ choice behavior in mice. The results suggest that altruistic behavior develops through reinforcement le...

Dominance effects of ion transport and ion transport regulator genes on the final weight and backfat thickness of Landrace pigs by dominance deviation analysis
Although there have been plenty of dominance deviation analysis, few studies have dealt with multiple phenotypes. Because researchers focused on multiple phenotypes (final weight and backfat thickness) of Land...

Overexpression of sweetpotato expansin cDNA (IbEXP1) increases seed yield in Arabidopsis
Results of transcriptome analyses suggest that expansin genes play an active role in seed development and yield, but gain- or loss-of-function studies have not yet elucidated the functional role(s) of the exp...

Bidirectional modulation of fear extinction by mediodorsal thalamic firing in mice
The mediodorsal thalamus links the medial prefrontal cortex and the amygdala in associative learning process in primates. Using mouse models, this study finds that the dual firing modes of mediodorsal thalamus...

Observational fear learning involves affective pain system and Cav1.2 Ca2+ channels in ACC
Primates can develop a conditioned fear response by witnessing other primates being subjected to adverse stimuli. Jeon et al. report that mice are capable of this form of observational fear conditioning and that ...

Translation of clock rhythmicity into neural firing in suprachiasmatic nucleus requires mGluR–PLCβ4 signaling
Phospholipase C β4 (PLCβ4) is expressed in the suprachiasmatic nucleus (SCN), as well as in tissues in the circadian entrainment pathway, including the retina and the lateral geniculate nucleus in the mouse1,2. U...

PLC-β1, activated via mGluRs, mediates activity-dependent differentiation in cerebral cortex
During development of the cerebral cortex, the invasion of thalamic axons and subsequent differentiation of cortical neurons are tightly coordinated. Here we provide evidence that glutamate neurotransmission t...

Insertion of a retroviral solo long terminal repeat in mdr-3 locus disrupts mRNA splicing in mice
Previously, the abermectin-induced neurotoxicity of subpopulation of CF-1 mice was shown to be caused by the deficiency of mdr-3 P-glycoprotein. Here, we have characterized the molecular nature of the mdr-3 gene...

The murine MHC encodes a mammalian homolog of bacterial ribosomal protein S13
The mouse major histocompatibility complex (MHC) contains many genes in addition to the classical immune response genes. We have screened overlap** cosmid clones covering 170 kb of the H-2K region for genes exp...
