Experimental exploration of a ribozyme neutral network using evolutionary algorithm and deep learning

open access: yesNature Communications, 2022
Neutral networks, which are sets of genotypes connected via single mutations that share the same phenotype, are important for evolvability. Here, the authors provide experimental evidence of a neutral network in an RNA enzyme using a high-throughput ...

Nucleic Acid Carriers Based on Precise Polymer Conjugates [PDF]

open access: yes, 2011
Polymer polydispersity, random conjugation of functional groups, and poorly understood structure–activity relationships have constantly hampered progress in the development of nucleic acid carriers.

DNA priming immunization is more effective than recombinant protein vaccine in eliciting antigen-specific B cell responses

open access: yesEmerging Microbes and Infections, 2021
While DNA prime-protein boost vaccination approach has been widely used in preclinical and clinical studies especially in the field of HIV vaccine development, the exact role of DNA immunization has not been fully identified.

Design, synthesis, conformational analysis and nucleic acid hybridisation properties of thymidyl pyrrolidine-amide oligonucleotide mimics (POM) [PDF]

open access: yes, 2003
Pyrrolidine-amide oligonucleotide mimics (POM) 1 were designed to be stereochemically and conformationally similar to natural nucleic acids, but with an oppositely charged, cationic backbone.

A novel splice variant of the human MSTN gene encodes a myostatin‐specific myostatin inhibitor

open access: yesJournal of Cachexia, Sarcopenia and Muscle, 2023
Background Myostatin, encoded by the MSTN gene comprising 3 exons, is a potent negative regulator of skeletal muscle growth. Although a variety of myostatin inhibitors have been invented for increasing muscle mass in muscle wasting diseases, no effective

Active RNAP pre-initiation sites are highly mutated by cytidine deaminases in yeast, with AID targeting small RNA genes

open access: yeseLife, 2014
Cytidine deaminases are single stranded DNA mutators diversifying antibodies and restricting viral infection. Improper access to the genome leads to translocations and mutations in B cells and contributes to the mutation landscape in cancer, such as ...

Identification and differentiation among chicken's, duck's, quail's, rabbit's and turkey's meat using PCR-RFLP technique [PDF]

open access: yesBiotechnology in Animal Husbandry, 2015
PCR-RFLP technique was developed for identification and differentiation among chicken's, duck's, quail's, rabbit's and turkey's meat. DNA from small amount of muscles (0.05 g) was extracted and a region of mitochondrial DNA (cytochrome-b gene) in chicken,
