Antennal transcriptome analysis and expression profiles of putative chemosensory soluble proteins in Histia rhodope Cramer (Lepidoptera: Zygaenidae)
In this study, we established antennal transcriptome of H. rhodope and ultimately identified 19 odorant binding proteins (OBPs), 23 chemosensory proteins (CSPs) and 4 Niemann-Pick type C2 proteins (NPC2s). The 19 OBPs, 6 CSPs and 4 NPC2s were assessed to validate the differential expressions between sexes, and between olfactory and non-olfactory tissues. 8 OBPs and 2 CSPs exhibited male-biased antennae expression, while 6 OBPs, 2 CSPs and HrhoNPC2a exhibited female-biased antennae expression. Moreover, 17 OBPs, 4 CSPs and 2 NPC2s were predominantly expressed in the antennae compared with non-olfactory tissues. HrhoOBP1 and...

Publication date: Available online 3 January 2020Source: Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsAuthor(s): Bo-Ping Zeng, Kui Kang, Hui-Juan Wang, Bi-Ying Pan, Cai-Di Xu, Bin Tang, Dao-Wei ZhangAbstractNilaparvata lugens is a serious threat to rice growth. Glycogen metabolism is one of the important physiological processes of insects, which is mainly regulated by glycogen synthase (GS) and glycogen phosphorylase (GP). In the present study, trehalose content was significantly reduced at 72 h after NlGP and NlGS knockdown, whereas glucose content was significantly increased at both 48 h and...

The distinct transcriptomes of fast-twitch and slow-twitch muscles in Mongolian horses
We examined the muscle fiber type population and produced deep RNA sequencing for different parts of skeletal muscles. And chose two of them with the highest difference in fast and slow muscle fiber population (splenius and gluteus medius) for comparing the gene expression profile of slow and fast muscle fiber types. We identified a total of 275 differentially expressed genes (DEGs), and 11 differentially expressed miRNAs (DEmiRs). In addition, target gene prediction and alternative splicing analysis were also performed. Significant correlations were found between the differentially expressed gene, miRNAs, and alternative ...

SEM observation of early shell formation and expression of biomineralization-related genes during larval development in the pearl oyster Pinctada fucata
Publication date: Available online 2 December 2019Source: Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsAuthor(s): Haimei Li, Lirong Bai, Xiaoyun Dong, Xiaohui Qi, Hongying Liu, Dahui YuAbstractShell formation of Pinctada fucata in larval development stages plays a crucial role in their survival. Scanning electron microscopy (SEM) was used to observe the morphological changes during larval development. We found that the early shell forms soon after enlargement of the blastopore at the anterior end of the trochophore stage and the complete shell forms in the spats stage, required for metamorphosis o...

Identification and comparative expression profiles of chemosensory genes in major chemoreception organs of a notorious pests, Laodelphax striatellus
In this study, we identified multi-gene chemosensory families from the transcriptome of SBPH olfactory organs and analyzed their expression patterns in male and female tissues. Among the chemosensory genes, 14 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), 7 sensory neuron membrane proteins (SNMPs) and 95 odorant receptors (ORs) were identified and annotated in SBPH olfactory organs. Based on expression profile and phylogenetic analysis, LstrOBP1, 2, 5, 6, 7, 10, LstrSNMP1, and most LstrORs showed an antennae-enriched expression pattern, which suggests an olfactory role for these genes. Relative expressi...

Genome-wide identification of JNK and p38 gene family in Ctenopharyngodon idella and their expression profiles in response to bacterial challenge
In this study, we analyzed the whole-genome database of the grass carp and identified 4 JNK and 6 p38 genes. JNK and p38 genes of grass carp were distributed in 7 out of 24 chromosomes. All JNK and p38 proteins contained characteristic dual-phosphorylation site. The JNKs contain a specific dual-phosphorylation consensus ((Thr-Pro-Tyr) that is different from that of the p38 proteins (Thr-Gly-Tyr). Deduced gene secondary structure analyses as well as the syntenic analyses further supported their annotation and orthologs. Results of tissue distribution detection revealed that JNK and p38 genes exhibited lower expression in he...

Blubber proteome response to repeated ACTH administration in a wild marine mammal
Publication date: Available online 22 November 2019Source: Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsAuthor(s): Jared Deyarmin, Ryan Hekman, Cory Champagne, Molly McCormley, Alicia Stephan, Daniel Crocker, Dorian Houser, Jane KhudyakovAbstractWhile the response to acute stress is adaptive in nature, repeated or chronic stress can impact an animal's fitness by depleting its energy stores and suppressing immune function and reproduction. This can be especially deleterious for species that rely on energy reserves to fuel key life history stages (e.g. reproduction), already experience physiological...

Chronic exposure to venlafaxine and increased water temperature reversibly alters microRNA in zebrafish gonads (Danio rerio)
Publication date: Available online 4 November 2019Source: Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsAuthor(s): Heather Ikert, Paul M. CraigAbstractMicroRNA (miRNA) are short, non-coding RNA that act by downregulating targeted mRNA transcripts. Only recently have they been used as endpoints in studies of aquatic toxicology. The purpose of this study was to determine the effect of an antidepressant contaminant, venlafaxine (VFX), and increased temperature on specific microRNA levels in zebrafish (Danio rerio) reproductive tissue. Adult zebrafish were exposed to one of four conditions; control, 1â...

Transcriptome analysis and weighted gene co-expression network reveals potential genes responses to heat stress in turbot Scophthalmus maximus
In this study, we performed transcriptome gene expression profiling of kidney tissue in turbot exposed to heat stress (20, 23, 25 and 28 °C); control fish were maintained at 14 °C. We investigated gene relationships based on weighted gene co-expression network analysis (WGCNA). Accordingly, enrichment analyses of GO terms and KEGG pathways showed that several pathways (e.g., fat metabolism, cell apoptosis, immune system, and insulin signaling) may be involved in the response of turbot to heat stress. Moreover, via WGCNA, we identified 19 modules: the dark grey module was mainly enriched in pathways associated with fa...
