Summary of transcription factors affecting gene expression in central Biology Diagrams Evidence has supported a broad role for apoptosis-related genes in cell-cycle progression, possibly through direct regulation of the E2F class of transcription factors or other activities
The E2F transcription factors are key regulators of cell cycle progression and the E2F field has made rapid advances since its advent in 1986. Yet, while our understanding of the roles and functions of the E2F family has made enormous progress, with each discovery new questions arise. Significance of the periodic transcription program. (a) Genes are expressed only during the cell-cycle phase needed.Genes required for DNA replication are expressed during S phase. (b) The temporal order of gene expression may aid in the construction of a protein complex only needed once per cycle.(c) While protein levels of cell-cycle regulators may remain constant, posttranslational
Coordinating gene expression during the cell cycle Biology Diagrams
Among 3028 cell cycle associated genes, 2125 genes are validated targets of 424 microRNAs; CDKN1A is a target of 46 miRNAs and miR-335 targets 301 genes. About 100 transcription factors had binding sites at potential promoter regions of 2722 genes and 329 microRNAs that target cell cycle associated genes. We presented the largest numbers of This work has revealed many new insights into how transcription of different G1-S cell cycle genes is restricted to G1 and how this is regulated by DNA replication checkpoint protein kinases as part of the checkpoint transcriptional response. Landman A, Futcher B. The G1 cyclin Cln3 promotes cell cycle entry via the transcription factor
Transcription factors (TFs) are key regulators of intrinsic cellular processes, such as differentiation and development, and of the cellular response to external perturbation through signaling pathways. In this review we focus on the role of TFs as a link between signaling pathways and gene regulati โฆ
Regulated Transcription: Effectively Using a Genomics ... Biology Diagrams
Classical regulators include the transcription factors E2F1 and FOXM1 that are required for the temporal control of gene expression in G1-S and G2-M stages of cell cycle, respectively 4,19,20,21 A list of 102 cell cycle genes was generated by combining 68 key cell cycle genes reported by ref. 74 with a manually curated list of 34 genes. The MYC target gene list was previously reported by
