Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation
FEBS Letters, EarlyView.Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Thermodynamic restrictions on evolutionary optimization of transcription factor proteins [PDF]
, 2007 Conformational fluctuations are believed to play an important role in the process by which transcription factor proteins locate and bind their target site on the genome of a bacterium. Using a simple model, we show that the binding time can be minimized,

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Transcription factor mutations in myelodysplastic/myeloproliferative neoplasms
Haematologica, 2010 Background Aberrant activation of tyrosine kinases, caused by either mutation or gene fusion, is of major importance for the development of many hematologic malignancies, particularly myeloproliferative neoplasms.

Transcription Factor-DNA Binding Via Machine Learning Ensembles [PDF]
, 2018 We present ensemble methods in a machine learning (ML) framework combining predictions from five known motif/binding site exploration algorithms. For a given TF the ensemble starts with position weight matrices (PWM's) for the motif, collected from the ...

Simple SVM based whole-genome segmentation [PDF]
, 2009 We present a support vector machine (SVM) based framework for DNA segmentation into binary classes. Two applications are explored: transcription start site prediction and transcription factor binding prediction.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Transcription factors and asthma [PDF]
European Respiratory Journal, 1998 Asthma is characterized by the expression of multiple genes for inflammatory proteins, such as cytokines, enzymes, receptors and adhesion molecules. This is orchestrated by transcription factors, which are proteins that bind to the promoter regions of these genes and may be activated by inflammatory stimuli, such as cytokines.

The transcription factor C/EBP-β mediates constitutive and LPS-inducible transcription of murine SerpinB2. [PDF]
PLoS ONE, 2013 SerpinB2 or plasminogen activator inhibitor type 2 (PAI-2) is highly induced in macrophages in response to inflammatory stimuli and is linked to the modulation of innate immunity, macrophage survival, and inhibition of plasminogen activators ...

Effect of natural genetic variation on enhancer selection and function. [PDF]
, 2013 The mechanisms by which genetic variation affects transcription regulation and phenotypes at the nucleotide level are incompletely understood. Here we use natural genetic variation as an in vivo mutagenesis screen to assess the genome-wide effects of ...
