Endophytic fungi are fungi that colonize internal tissues of plants; several biologically active compounds have been isolated from these fungi. There are few studies of compounds isolated from endophytic fungi of Amazon plants. Thus, this study aimed the isolation and structural identification of ergosterol (1), ergosterol peroxide (2), mevalonolactone (3), cytochalasin B (4) and cytochalasin H...

The export of messenger RNAs (mRNAs) is the final of several nuclear posttranscriptional steps of gene expression. The formation of export-competent mRNPs involves the recruitment of export factors that are assumed to facilitate transport of the mature mRNAs. Using in vitro splicing assays, we show that a core set of export factors, including ALYREF, UAP56 and DDX39, readily associate with the ...

Arc is a unique immediate early gene (IEG) whose expression is induced as synapses are modified during learning. Newly-synthesized Arc mRNA is rapidly transported throughout dendrites and localizes near recently activated synapses. Arc mRNA levels are regulated by rapid degradation, which is accelerated by synaptic activity in a translation-dependent process. One possible mechanism is nonsense-...

Abstract. Ermawati D, Panjono, Bintara S, Hartatik T. 2022. Diversity of partial sequence leptin gene (Exon 3) in crossbred cattle compared to GenBank database. Biodiversitas 23: 5614-5620. Genetic marker method that is often used select Single Polymorphism Nucleotide (SNP). Polymorphisms (SNP) has been found various candidate genes, one which the gene. Leptin a affects reproduction and weight....

The study aimed to identify polymorphism of LEP, and STAT5A milk-producing genes their association with production traits in Rathi cattle. An overall 160 animals were selected from a population cattle Livestock Research Station, Rajasthan University Veterinary Animals Sciences, Bikaner (Rajasthan). phenotypic information on total milk yield, peak yield lactation length recorded the years 2012- ...

RNA-specific adenosine deaminase (ADAR1) catalyzes the deamination of adenosine to inosine in viral and cellular RNAs. Two size forms of the ADAR1 editing enzyme are known, an IFN-inducible approximately 150-kDa protein and a constitutively expressed N-terminally truncated approximately 110-kDa protein. We have now identified alternative exon 1 structures of human ADAR1 transcripts that initiat...
