Abstract:
... The timely transition from vegetative to reproductive growth is vital for reproductive success in plants. It has been suggested that messenger RNA 3'-end processing plays a role in this transition. Specifically, two autonomous factors in the Arabidopsis thaliana flowering time control pathway, FY and FCA, are required for the alternative polyadenylation of FCA pre-mRNA. In this paper we provide ev ...

Abstract:
... Polyadenylation factor CLP1 is essential for mRNA 3'-end processing in yeast and mammals. The Arabidopsis (Arabidopsis thaliana) CLP1-SIMILAR PROTEIN3 (CLPS3) is an ortholog of human hCLP1. CLPS3 was previously found to be a subunit in the affinity-purified PCFS4-TAP (tandem affinity purification) complex involved in the alternative polyadenylation of FCA and flowering time control in Arabidopsis. ...

Abstract:
... Based on comparative genome analyses, the increases in protein-coding gene number could not account for the increases of morphological and behavioral complexity of higher eukaryotes. Transcriptional regulations, alternative splicing and the involvement of non-coding RNA in gene expression regulations have been credited for the drastic increase of transcriptome complexity. However, an emerging them ...

In an attempt to perform RNA immuno-precipitation assays of Arabidopsis proteins, we found an EDTA-dependent RNase activity from Arabidopsis suspension tissue cultures. Further investigations proved that the EDTA-dependent RNase activity was plant specific. Characterization of the RNase activity in ...

Abstract:
... Cleavage and polyadenylation of precursor mRNA is an essential process for mRNA maturation. Among the 15 to 20 protein factors required for this process, a subgroup of proteins is needed for both cleavage and polyadenylation in plants and animals. This subgroup of proteins is known as the cleavage and polyadenylation specificity factor (CPSF). To explore the in vivo structural features of plant CP ...

Abstract:
... Injectable bone implants have been widely used in bone tissue repairs, including the treatment of comminuted bone fractures (CBF). However, most injectable bone implants are not suitable for the treatment of CBF because of their weak tissue adhesion strengths and minimal osteoinduction. Citrate has been recently reported to promote bone formation through enhanced bioceramic integration and osteoin ...

Abstract:
... Widespread use of pentachlorophenol (PCP) in schistosomiasis endemic areas had led to ubiquitous exposure to PCP and its residues. Numerous studies had revealed that occupational PCP exposure probably increased risk of cancers, but whether long-term community-level exposure to PCP generates the similarly carcinogenic effect, seldom studies focused on it. This study was to explore the cancer risks ...

... The field of molecular evolution started with the alignment of a few protein sequences in the early 1960s. Among the first results found, the genetic equidistance result has turned out to be the most unexpected. It directly inspired the ad hoc universal molecular clock hypothesis that in turn inspired the neutral theory. Unfortunately, however, what is only a maximum distance phenomenon was mistak ...
