The genus Cladophora Kutzing (Ulvophyceae) as a globally distributed ecological engineer [PDF]

, 2013
The green algal genus Cladophora forms conspicuous nearshore populations in marine and freshwaters worldwide, commonly dominating peri-phyton communities. As the result of human activities, including the nutrient pollution of nearshore waters, Cladophora-

Centrosomal protein 120 promotes centrosome amplification and gastric cancer progression via USP54-mediated deubiquitination of PLK4

iScience, 2023
Summary: Centrosomal protein 120 (CEP120) is a 120 kDa centrosome protein that plays an important role in centrosome replication. Overexpression of CEP120 can lead to centrosome duplicate abnormality, which is closely associated with tumorigenesis and ...

mRNA splicing is modulated by intronic microRNAs

iScience, 2023
Summary: Splicing of transcripts is catalyzed by the spliceosome, a mega-complex consisting of hundreds of proteins and five snRNAs, which employs direct interactions. When U1 snRNA forms high-affinity binding, namely more than eight base pairs, with the
