Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Tyrosine Phosphorylation Regulates Maturation of Receptor Tyrosine Kinases [PDF]

Molecular and Cellular Biology, 2005
Constitutive activation of receptor tyrosine kinases (RTKs) is a frequent event in human cancer cells. Activating mutations in Fms-like tyrosine kinase 3 (FLT-3), notably, internal tandem duplications in the juxtamembrane domain (FLT-3 ITD), have been causally linked to acute myeloid leukemia.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

JNK and ERK8 as downstream effectors of receptor tyrosine kinases [PDF]

, 2006
MAP kinases are a super-family of serine-threonine protein kinases expressed in all eukaryotic cells. In mammals, there are many MAP kinases with different biological functions, grouped in distinctly regulated groups, ERK1/2 (extracellular signal related

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

Chromatin Structures of the Rat Tyrosine Aminotransferase Gene Relate to the Function of Its cis-Acting Elements [PDF]

, 1990
The relationship between DNase I-hypersensitive sites (HSs) and transcriptional enhancers of the rat tyrosine aminotransferase (TAT) gene was examined by comparing HSs in and around the TAT gene with the activity of the corresponding DNA sequences in ...

The Effect of the Acidic Gas Pollutant on Wool Keratin Fiber Structure

Journal of Natural Fibers, 2022
Increase in air pollution caused by acidic gases, such as nitrogen dioxide, call for the need to study potential effects on the structure of textile materials.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Protein recruitment to receptor tyrosine kinase-mediated early signalling complexes. [PDF]

, 2007
Receptor tyrosine kinase (RTK) signalling regulates the activation of numerous cellular processes in response to various external stimuli. Spatio-temporal regulation of protein recruitment to activated tyrosine kinase receptors is important for the ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
