Role of RNA modifications in carcinogenesis and carcinogen damage response
Molecular Carcinogenesis, Volume 62, Issue 1, Page 24-37, January 2023., 2023 Abstract The field of epitranscriptomics encompasses the study of post‐transcriptional RNA modifications and their regulatory enzymes. Among the numerous RNA modifications, N6‐methyladenosine (m6A) has been identified as the most common internal modification of messenger RNA (mRNA).

The 16s/23s ribosomal spacer region as a target for DNA probes to identify eubacteria. [PDF]
Genome Research, 1991 Variable regions of the 16s ribosomal RNA have been frequently used as the target for DNA probes to identify microorganisms. In some situations, however, there is very little sequence variation observed between the 16s rRNA genes of closely related microorganisms.

Long Term Weight Cycling Affects Fecal Microbiota of Mice
Molecular Nutrition &Food Research, Volume 66, Issue 23, December 2022., 2022 Fighting obesity through dieting is not always sustained and results in a subsequent weight gain, a phenomenon referred to as weight cycling. We determined whether weight cycling affects mouse fecal bacteria on a long‐term basis. Compared to continuous High Fat (HF) or Low Fat (LF) diets, cyclic diet specifically alters the composition and function of ...

Heterogeneous diversity of spacers within CRISPR [PDF]
arXiv, 2010 Clustered regularly interspaced short palindromic repeats (CRISPR) in bacterial and archaeal DNA have recently been shown to be a new type of anti-viral immune system in these organisms. We here study the diversity of spacers in CRISPR under selective pressure.

The size of the immune repertoire of bacteria [PDF]
, 2019 Some bacteria and archaea possess an immune system, based on the CRISPR-Cas mechanism, that confers adaptive immunity against phage. In such species, individual bacteria maintain a "cassette" of viral DNA elements called spacers as a memory of past infections. The typical cassette contains a few dozen spacers.
