Frontiers in Cell and Developmental Biology, 2022 The cladoceran crustacean Daphnia produces only females by parthenogenesis in a healthy population. However, in response to environmental declines such as crowding and lack of foods, it produces eggs destined to become males that are genetically ...

Regulation of transcription in cancer
Frontiers in Bioscience, 2012 The purpose of this article is to provide an overview on the regulation of transcription in cancer cells. We describe here standard mechanisms of transcription in eukaryotic cells, an influence of common promoter polymorphisms contributing to malignant progression and DNA methylation as significant aspect of gene regulation.

Transcriptional Regulation by P53 [PDF]
Cold Spring Harbor Perspectives in Biology, 2010 Inactivation of p53 is critical for the formation of most tumors. Illumination of the key function(s) of p53 protein in protecting cells from becoming cancerous is therefore a worthy goal. Arguably p53's most important function is to act as a transcription factor that directly regulates perhaps several hundred of the cell's RNA polymerase II (RNAP II ...

Regulation of Transcription of Coronaviruses [PDF]
, 1995 To study factors involved in regulation of transcription of coronaviruses, we constructed defective interfering (DI) RNAs containing sg RNA promoters at multiple positions. Analysis of the amounts of sg DI RNA produced by these DIs resulted in the following observations: (i) a downstream promoter downregulates an upstream promoter; (ii) an upstream ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
