Summary
Mouse pluripotent stem cells grown in defined media exhibit a naive ground state. Recent findings reveal distinct transcriptional and epigenomic landscapes in these naive stem cells compared to serum-exposed cells.
Area of Science:
- Stem cell biology
- Developmental biology
- Epigenetics
Background:
- Mouse pluripotent stem cells (PSCs) are crucial for developmental studies.
- Traditional PSC culture uses serum-containing media, which may not represent the true ground state.
- Defined media with signaling inhibitors offer a controlled environment for PSC culture.
Discussion:
- Marks et al. (2012) investigated the differences between naive and serum-exposed mouse PSCs.
- The study focused on transcriptional and epigenomic variations.
- Understanding these differences is key to defining the pluripotent ground state.
Key Insights:
- Naive PSCs cultured in defined media display a distinct ground state.
- Significant differences exist in gene expression and epigenetic modifications between naive and serum-exposed PSCs.
- These findings refine our understanding of pluripotency.
Outlook:
- Further research can explore the functional implications of these epigenetic and transcriptional differences.
- This work may guide the development of improved stem cell culture techniques.
- Investigating similar states in other species could reveal conserved mechanisms of pluripotency.

02:42Transcription Attenuation in Prokaryotes
Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin structure. Bacteria use these hairpins to regulate the transcription process and control the synthesis of several amino acids including histidine, lysine, threonine, and phenylalanine. Transcription attenuation takes place in the non-coding regions of mRNA.
There are several different mechanisms used to attenuate transcription. In ribosome mediated...

02:27Nonsense-mediated mRNA Decay
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

01:47Transcription Initiation
Initiation is the first step of transcription in eukaryotes. Prokaryotic RNA Polymerase (RNAP) can bind to the template DNA and start transcribing. On the other hand, transcription in eukaryotes requires additional proteins, called transcription factors, to first bind to the promoter region in the DNA template. This binding helps recruit the specific RNAP that can assemble on the DNA and start transcription.

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
01:53Bacterial Transcription
RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:
