Extreme changes to gene expression associated with homoploid hybrid speciation.

Hegarty Matthew J MJ Barker Gary L GL Brennan Adrian C AC Edwards Keith J KJ Abbott Richard J RJ Hiscock Simon J SJ

Molecular ecology 20090116 5

Hybridization is an important cause of abrupt speciation. Hybrid speciation without a change in ploidy (homoploid hybrid speciation) is well-established in plants but has also been reported in animals and fungi. A notable example of recent homoploid hybrid speciation is Senecio squalidus (Oxford ragwort), which originated in the UK in the 18th Century following introduction of hybrid material from a hybrid zone between S. chrysanthemifolius and S. aethnensis on Mount Etna, Sicily. To investigate ...[more]

Transcription profiling of human seminiferous tubules from subfertile/infertile patients undergoing testicular sperm extraction as part of their treatment

Project description:43 biopsies were obtained from subfertile/infertile patients undergoing testicular sperm extraction (TESE) as part of their treatment. Labelled cDNAs were compared to a reference normal testis RNA (Ambion).

Targeting ATP2B1 impairs PI3K/Akt/Forkhead box (Fox) transcription factor signaling and reduces SARS-COV-2 infection and replication

Project description:RNA-seq of human cells Edited using CRISPR vs parental and Unedited control. We identified a rare homozygous intronic variant in the ATP2B1 locus (rs111337717; chr12:89643729, T>C) that is associated with the severity of COVID-19 (i.e., symptomatic versus asymptomatic patients). Next, we employed CRISPR/Cas9 technology to develop the disease mutation observed in high-risk patients. Several edited single colonies were picked and expanded followed by DNA sequencing, and four clones with desired homozygous modifications were identified. The transcriptional profiles of N=4 C/C clones were compared then to those of T/T controls comprising one parental cell line and three unedited post-selection HEK293T cell clones.

Proteomes and Histone Crotonylation Analysis Reveals the Importance of Crotonylation Low Temperature in Chrysanthemum

Project description:Chrysanthemum is a garden plant with good economic benefit and high ornamental value. Chrysanthemum in the key period of flowering in autumn and winter, vulnerable to cold damage, affecting the normal growth of the chrysanthemum plant and even death. little is known regarding the study of histone crotonylation in plant cold response. In this study, we first obtained reference chrysanthemum transcriptome data via RNA sequencing. Next, we quantitatively investigated the chrysanthemum proteome, crotonylation, and the association between them in chrysanthemum following low temperature. In total, 365669 unigenes, 6693 proteins and 2017 crotonylation sites were quantified under low temperature stress. There were 24631 up-regulated and 22648 down-regulated unigenes (absolute log2-fold change > 1 and P value<0.05), 393 up-regulated and 500 down-regulated proteins using a 1.2-fold threshold (P<0.05). The lysine crotonylation mainly influenced in photosynthesis, ribosome, antioxidant enzyme and ROS system. In the process of low temperature, 61 lysine crotonylation sites in 89 proteins were up-regulated and 87 lysine crotonylation sites in 72 proteins are down-regulated (1.2-fold threshold, P<0.05).

SynGAP variant from Japanese ALS cohort alters the recruitment of RNA binding proteins

Project description:FUS is one of the pathogenic RNA-binding proteins for amyotrophic lateral sclerosis (ALS). We previously reported that FUS stabilized SynGAP mRNA at its 3’UTR and maintained spine maturation and cognitive function in mice. To elucidate whether this mechanism could be pathogenic for ALS, we identified SynGAP 3’UTR variant at the binding site of FUS, different from that in mice, from a multicenter cohort in Japan. Human induced pluripotent stem cells (hiPSC)-derived motor neurons with SynGAP variant showed spine abnormality with aberrant SynGAP splicing. To evaluate how SynGAP variant altered the access of RNA binding proteins to SynGAP 3'UTR, we performed pull down assay by using biotinylated RNA probes with or without the variant.

Mechanism of isorhynchophylline in lipopolysaccharide-induced acute lung injury based on proteomic technology

Project description:Abstract Isorhynchophylline, a tetracyclic indole alkaloid, has anti-inflammatory and antioxidant activities against cardiovascular diseases and central nervous system disorders. Acute lung injury (ALI) is a manifestation of inflammation concentrated in the lungs and has a high incidence rate and mortality. Here, we established a mouse model of ALI and observed the effects of isorhynchophylline. Proteomic results showed that 5727 proteins were detected in mouse lung tissues, and 16 proteins were screened out. Isorhynchophylline could reverse the trend of these differential proteins. In addition, isorhynchophylline can act on integrin alpha M to reduce neutrophil recruitment and thereby produce anti-inflammatory effects and may suppress neutrophil migration through the leukocyte transendothelial migration pathway. TUNEL and RT-PCR experiments revealed that LPS-induced ALI in mice increases the apoptosis of lung tissues, damage to alveolar epithelial cells and levels of inflammatory factors. Treatment with isorhynchophylline can repair tissues, improve lung tissue pathology and reduce lung inflammation.
