Leptin receptor （LepRb） signaling pathway in the hypothalamus of the forebrain controls food intake and energy expenditure in response to an altered energy state. Defects in the LepRb signaling pathway can result in leptin-resistance and obesity. Leucine zipper transcription factor like 1.（Lztfl1./BBS1. is a member of the Bardet-Biedl syndrome （BBS） gene family. Human BBS patients have a wide range of pathologies including obesity. The cellular and molecular mechanisms underlying Lztfl1.regulated obesity are unknown. Here, we generated Lztfl1.f/f mouse model in which Lztfl1.can be deleted globally and in tissue-specific manner. Global Lztfl1.deficiency resulted in pleiotropic phenotypes including obesity. Lztfl1.-/- mice are hyperphagic and showed similar energy expenditure as WT littermates. The obese phenotype of Lztfl1./- mice is caused by the loss of Lztfl1.in the brain but not in the ***1./- mice are leptin-resistant. Inactivation of Lztfl1.abolished phosphorylation of Stat3 in the LepRb signaling pathway in the hypothalamus upon leptin stimulation. Deletion of Lztfl1.had no effect on LepRb membrane localization. Furthermore, we observed that Lztfl1./- mouse embryonic fibroblasts （MEFs） have significantly longer cilia than WT MEFs. We identified several proteins that potentially interact with Lztfl1. As these proteins are known to be involved in regulation of actin/cytoskeleton dynamics, we suggest that Lztfl1.may regulate leptin signaling and ciliary structure via these proteins. Our study identified Lztfl1.as a novel player in the LepRb signaling pathway in the hypothalamus that controls energy homeostasis.

Retinol dehydrogenase, RDHll, is essential for the heart development and cardiac performance in zebrafish

Chinese Medical Journal 2013年第4期126卷 722-728页

作者： wang Wei ZHANG Li-feng GUI Yong-hao SONG Hou-{1. Cardiovascular Center Children's Hospital Fudan University Shanghai 201102 China Department of Pediatrics Shanghai Medical College of Fudan University Shanghai 200032 China Department of Molecular Genetics Shanghai Medical School & Key Laboratory of Molecular Medicine Ministry of Education Fudan University Shanghai 200032 China

Background Retinoic acid （RA） is a potent signaling molecule that plays pleiotropic roles in patterning, morphogenesis, and organogenesis during embryonic development. The synthesis from retinol （vitamin A） to retinoic acid requires two sequential oxidative steps. The first step involves the oxidation of retinol to retinal through the action of retinol dehydrogenases. Retinol dehydrogenasesll （RDHll） is a novel zebrafish retinol dehydrogenase. Herein we investigated the role of zebrafish RDHll in heart development and cardiac performance in detail. Methods RDHll specific morpholino was used to reduce the function of RDHll in zebrafish. The gene expressions were observed by using whole mount in situ hybridization. Heart rates were observed and recorded under the microscope from 24 to 72 hours post fertilization （hpf）. The cardiac performance was analyzed by measuring ventricular shortening fraction （VSF）. Results The knock-down of RDHll led to abnormal neural crest cells migration and reduced numbers of neural crest cells in RDHll morphant embryos. The reduced numbers of cardiac neural crest cells also can be seen in RDHll morphant embryos. Furthermore, the morpholino-mediated knock-down of RDHll resulted in the abnormal heart loop. The left-right determining genes expression pattern was altered in RDHll morphant embryos. The impaired cardiac performance was observed in RDHll morphant embryos. Taken together, these data demonstrate that RDHll is essential for the heart development and cardiac performance in zebrafish. Conclusions RDHll plays a important role in the neural crest cells development, and then ultimately affects the heart loop and cardiac performance. These results show for the first time that an enzyme involved in the retinol to retinaldehyde conversion participate in the heart development and cardiac performance in zebrafish.

Auxin is an important phytohormone in plants, and auxin signaling pathways in rice play key roles in regulating its growth, development, and productivity. To investigate how rice grain yield traits are regulated by auxin signaling pathways and to facilitate their application in rice improvement, we validated the functional relationships among regulatory genes such as OsIAA1., OsSK41. and OsARF21.that are involved in one of the auxin(OsIAA1.) signaling pathways. We assessed the phenotypic effects of these genes on several grain yield traits across two environments using knockout and/or overexpression transgenic *** on the results, we constructed a model that showed how grain yield traits were regulated by OsIAA1. and OsTIR1. OsAFB2, and OsSK41.and OsmiR393 in the OsSK41.OsIAA1.-OsARF module and by OsARF21.in the transcriptional regulation of downstream auxin response genes in the OsSK41.OsIAA1.-OsARF module. The population genomic analyses revealed rich genetic diversity and the presence of major functional alleles at most of these loci in rice populations. The strong differentiation of many major alleles between Xian/indica and Geng/japonica subspecies and/or among modern varieties and landraces suggested that they contributed to improved productivity during evolution and breeding. We identified several important aspects associated with the genetic and molecular bases of rice grain and yield traits that were regulated by auxin signaling *** also suggested rice auxin response factor(OsARF) activators as candidate target genes for improving specific target traits by overexpression and/or editing subspecies-specific alleles and by searching and pyramiding the ‘best' gene allelic combinations at multiple regulatory genes in auxin signaling pathways in rice breeding programs.

In the current study,we sought to investigate whether T-type Ca^(2+)channels(TCCs)in the brain are involved in generating post-anesthetic hyperexcitatory behaviors(PAHBs).We found that younger rat pups(postnatal days 9-1.)had a higher incidence of PAHBs and higher PAHB scores than older pups(postnatal days1.-1.)during emergence from sevoflurane *** power spectrum of the theta oscillations(4 Hz-8 Hz)in the prefrontal cortex was significantly enhanced in younger pups when PAHBs occurred,while there were no significant changes in older *** the power of theta oscillations and the level of PAHBs were significantly reduced by the administration of TCC ***,the sensitivity of TCCs in the medial dorsal thalamic nucleus to sevoflurane was found to increase with age by investigating the kinetic properties of TCCs in *** were activated by potentiated GABAergic depolarization with a sub-anesthetic dose of sevoflurane(1.).These data suggest that(1.TCCs in the brain contribute to the generation of PAHBs and the concomitant electroencephalographic changes;(2)the stronger inhibitory effect of sevoflurane contributes to the lack of PAHBs in older rats;and(3)the contribution of TCCs to PAHBs is not mediated by a direct effect of sevoflurane on TCCs.
