Project description:QN Orange scallops is new strain with carotenoid deposition in orange adductor muscle, which provided suitable model for studying carotenoid accumulation. The present study was conducted to further understand the role of VPS29 in carotenoids deposition process via RNA interference (RNAi) of VPS29. Transcriptomic analysis revealed 534 differentially expressed genes (DEGs) between the groups without and with RNAi, among which were 288 upregulated and 246 were downregulated. Among these DGEs, genes related to carotenoids biosynthesis decrease in the expression of low-density lipoprotein receptor domain class (LDLR), cytochrome P450 (CYP 450), Niemann Pick C1-like 1 (NPC1L1) and ATP binding cassette transporter (ABC transporter) were identified. These results indicated that VPS29 played a vital role on carotenoids deposition by regulating other genes.

Project description:QN Orange scallop was interspecific hybrids with orange adductor muscles. Previous studies shown the accumulation of carotenoids was present in QN Orange scallops. In this study, analysis of miRNA expression profiles was performed to explore possibly regulatory patterns in carotenoid accumulation in adductor muscles of QN Orange scallops. Based on small RNA sequencing, a total of 3289 miRNAs and 91 differential expression miRNAs were identified between white and orange adductor muscles, respectively. GO and KEGG enrichment analysis of target genes of DE miRNA enriched in the transmembrane transporter activity-related pathways, kinase activity-related pathways, signal transduction-related pathways, ABC transporters, Retinol metabolism, lipid related metabolism and calcium signaling pathway.

Project description:Boihai Red is new strains of inter-specific hybridizing the bay scallop (Argopecten irradians irradians) with the Peruvian scallop (Argopecten purpuratus). Orange color variant of adductor muscle have been developed through successive selective breeding in this strain. In the present study,proteomic were conducted on orange and white adductor muscle tissues.Notably, 74 differentially expressed proteins (DEPs) were identified by lable free proteomics, including 36 up and 38 down regulated. In DEGs, apolipophorin, CYP450 and tyrosinase were expressed highly in orange adductor muscle tissues, which related to carotenoids or melanin. In DEPs, high expression of VPS and TIF in orange adductor muscle tissues indicated that proteins outside the carotenoid pathway might also affect carotenoid biosynthesis. In addition, RAB11A related to melanin was also expressed highly in orange adductor muscle tissues at protein level. It is probable that not only carotenoids, but also melanin act on orange color of adductor muscle. This study provides valuable genetic resources for understanding underlying mechanisms and pathways of adductor muscle color.

Orange color variant of adductor muscle have been developed through successive selective breeding in this strain. In the present study, transcriptomic was conducted on orange and white adductor muscle tissues.

Project description:We performed the first quantitative proteomics analysis of differences between striated (fast) and catch (slow) adductor muscle in Yesso scallop (Patinopecten yessoensis), with the goal to uncover muscle specific genes and proteins, as well as enzymes of metabolic pathways in fast and slow adductor muscle of scallops. The present findings highlight the functional roles of muscle contractile proteins, calcium signaling pathways, membrane and extracellular matrix proteins, and glycogen metabolism involved in the different contractile and metabolic properties between fast and slow muscles. The present findings will help better understand the molecular basis underlying muscle contraction and its physiological regulation in invertebrates.

Project description:BackgroundColor polymorphism, a high-valued trait, is frequently observed in molluscan shellfish. The QN Orange scallop, a new scallop strain successively selected from the interspecific hybrids of the bay scallop (Argopecten irradians irradians) and the Peruvian scallop (Argopecten purpuratus), is distinguished from other scallops by its orange adductor muscles. In this study, to reveal the mechanisms of the formation of adductor muscle coloration in the QN Orange scallops, we compared the proteome and transcriptome of orange adductor muscles of the QN Orange and those of white adductor muscles of the Bohai Red scallop, another strain selected from the interspecific hybrids of the bay scallop and the Peruvian scallop.ResultsTranscriptomic analysis revealed 416 differentially expressed genes (DEGs) between white and orange adductor muscles, among which 216 were upregulated and 200 were downregulated. Seventy-four differentially expressed proteins (DEPs), including 36 upregulated and 38 downregulated proteins, were identified through label-free proteomics. Among the identified DEGs and DEPs, genes related to carotenoids biosynthesis including apolipophorin, and Cytochrome P450 and those related to melanin biosynthesis including tyrosinase and Ras-related protein Rab-11A were found to express at higher levels in orange adductor muscles. The high expression levels of VPS (vacuolar protein sorting) and TIF (translation initiation factor) in orange adductor muscle tissues indicated that carotenoid accumulation may be affected by proteins outside of the carotenoid pathway.ConclusionsOur results implied that the coloration of orange adductor muscles in the QN Orange scallops may be controlled by genes modulating accumulation of carotenoids and melanins. This study may provide valuable information for understanding the mechanisms and pathways underlying adductor muscle coloration in molluscan shellfish.

Project description:The naphthalene diimide compound QN-302, designed to bind to G-quadruplex DNA sequences within the promoter regions of cancer-related genes, has high anti-proliferative activity in pancreatic cancer cell lines and anti-tumor activity in several experimental models for the disease. We show here that QN-302 also causes down-regulation of the expression of the S100P gene and the S100P protein in cells and in vivo. This protein is well-established as being involved in key proliferation and motility pathways in several human cancers and has been identified as a potential biomarker in pancreatic cancer. The S100P gene contains 60 putative quadruplex-forming sequences, one of which is in the promoter region, 48 nucleotides up-stream from the transcription start site. We report biophysical and molecular modeling studies showing that this sequence forms a highly stable G-quadruplex in vitro, which is further stabilized by QN-302. We also report transcriptome analyses showing that S100P expression is highly upregulated in tissues from human pancreatic cancer tumors, compared to normal pancreas material. The extent of up-regulation is dependent on the degree of differentiation of tumor cells, with the most poorly differentiated, from more advanced disease, having the highest level of S100P expression. The experimental drug QN-302 is currently in pre-IND development (as of Q1 2023) and its ability to down-regulate S100P protein expression supports a role for this protein as a marker of therapeutic response in pancreatic cancer. These results are also consistent with the hypothesis that the S100P promoter G-quadruplex is a potential therapeutic target in pancreatic cancer at the transcriptional level for QN-302.

Project description:In 1976, a spontaneous mutant derived from Poncirus trifoliata (L.) Raf with short juvenile phase, namely, precocious trifoliate orange, was found in Yichang, Hubei province, China. Compared with 6 to 8 years of the wild-type trifoliate orange, almost all of the seedlings germinated from precocious trifoliate orange only have 1 to 2 years’ juvenile period, and 20% seedlings even flowered in the year after germination. Therefore, precocious trifoliate orange is an ideal material for studying the role of miRNAs involved in citrus juvenile and adult developmental stages. To characterize these miRNAs expressed at the juvenile and adult development stages of citrus, Affymetrix miRNA arrays were used to generate miRNA profiles of shoot meristems of trifoliate orange, the results revealed that some miRNAs were down-regulated expressed at adult stage compared with juvenile stage. Detailed comparison of the expression patterns of miRNAs and corresponding target genes revealed the negative correlation between them, while few of them are positively correlated.
