A Repressor Protein Complex Regulates Leaf Growth in Arabidopsis [PDF]
Cell number is an important determinant of final organ size. In the leaf, a large proportion of cells are derived from the stomatal lineage. Meristemoids, which are stem cell-like precursor cells, undergo asymmetric divisions, generating several pavement cells adjacent to the two guard cells.

A dominant repressor version of the tomatoSl-ERF.B3gene confers ethylene hypersensitivity via feedback regulation of ethylene signaling and response components [PDF]
Ethylene Response Factors (ERFs) are downstream components of the ethylene signal transduction pathway, although their role in ethylene-dependent developmental processes remains poorly understood. As the ethylene-inducible tomato Sl-ERF.B3 has been shown

The trans-activation domain of the sporulation response regulator Spo0A revealed by X-ray crystallography [PDF]
Sporulation in Bacillus involves the induction of scores of genes in a temporally and spatially co-ordinated programme of cell development. Its initiation is under the control of an expanded two-component signal transduction system termed a phosphorelay.

The PRH/Hex repressor protein causes nuclear retention of Groucho/TLE co-repressors [PDF]
The PRH (proline-rich homeodomain) [also known as Hex (haematopoietically expressed homeobox)] protein is a transcription factor that functions as an important regulator of vertebrate development and many other processes in the adult including haematopoiesis.

DNA looping: the consequences and its control [PDF]
The formation of DNA loops by proteins and protein complexes is ubiquitous to many fundamental cellular processes, including transcription, recombination, and replication.

Diffusion of transcription factors can drastically enhance the noise in gene expression [PDF]
We study by simulation the effect of the diffusive motion of repressor molecules on the noise in mRNA and protein levels in the case of a repressed gene.

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

A quantitative comparison of sRNA-based and protein-based gene regulation [PDF]
Small, non-coding RNAs (sRNAs) play important roles as genetic regulators in prokaryotes. sRNAs act post-transcriptionally via complementary pairing with target mRNAs to regulate protein expression.

Chemical synthesis of a fully active transcriptional repressor protein. [PDF]
Plasmid pLS1-encoded 45-amino acid transcriptional repressor CopG (formerly RepA) has been chemically synthesized. A one-step purification of the synthetic protein has been developed, which yields high levels of pure protein with low or no contamination of truncated products.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.
