PUF family proteins are well-conserved regulators of cell proliferation in different developmental processes. They regulate target mRNAs by promoting degradation or by influencing translation through interaction with the translation initiation machinery. Here we show that Caenorhabditis elegans PUF-8 functions redundantly with the nuclear protein TCER-1 in the post-transcriptional maintenance o...

BACKGROUND Due to their modular repeat structure, Pumilio/fem-3 mRNA binding factor (PUF) proteins are promising candidates for designer RNA-binding protein (RBP) engineering. To further facilitate the application of the PUF domain for the sequence-specific RBP engineering, a rapid cloning approach is desirable that would allow efficient introduction of multiple key amino acid mutations in the ...

BACKGROUND Cardiorenal syndrome type 2 (CRS-2) is common in end-stage chronic heart failure (CHF). Peritoneal ultrafiltration (pUF) may entail clinical functional improvement and a reduction in hospitalizations. METHODS Thirty-nine consecutive end-stage CHF patients with stable CRS-2 were initiated on ambulatory pUF after interdisciplinary cardiological/nephrological evaluation and prospectiv...

PUF proteins are a conserved family of RNA binding proteins that regulate RNA stability and translation by binding to specific sequences in 3'-untranslated regions. Drosophila PUMILIO and C. elegans FBF are essential for self-renewal of germline stem cells, suggesting that a common function of PUF proteins may be to sustain mitotic proliferation of stem cells. Here, we show that PUF-8, the C. e...

Although the human genome project has been completed for some time, the issue of the number of transcribed genes with identifiable biological functions remains unresolved. We used zebrafish as a model organism to study the functions of Ka/Ks-predicted novel human exons, which were identified from a comparative evolutionary genomics analysis.In this study, a novel gene, designated as puf-A, was ...

Physical Unclonable Function (PUF) is hardware analog of a one-way function which can address hardware security issues such as device authentication, generating secret keys, producing seeds for Random Number Generators, etc. Traditional silicon PUFs are based on delay (Ring Oscillator PUFs and Arbiter PUFs) or memory structures (like SRAM). In this paper, we propose a novel idea of a very fast,...
