Molecular architecture of a cylindrical self-assembly at human centrosomes

open access: yesNature Communications, 2019
The centrosome is a membraneless organelle composed of two centrioles and an amorphous pericentriolar material but the overall centrosome organizations remains unknown.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Structural basis of human 20S proteasome biogenesis

open access: yesNature Communications
New proteasomes are produced to accommodate increases in cellular catabolic demand and prevent the accumulation of cytotoxic proteins. Formation of the proteasomal 20S core complex relies on the function of the five chaperones PAC1-4 and POMP.

Metabolic effects of cancer

open access: yesJournal of British Surgery, 1990
Abstract The potential causes of deranged metabolism in cancer are discussed with emphasis on changes in energy metabolism of glucose, fat and protein. The implications of these changes for the treatment of cachexia are then considered.

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

open access: yesMolecular 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.

Causal association between oral microbiota and oral cancer: a mendelian randomization study

open access: yesScientific Reports
Many studies have reported an association between oral microbiota and oral cancer (OC). Yet, the causal relationship between oral microbiota and OC remains undetermined.

Cancer Trends: Cancer of the liver and biliary tract

open access: yes, 2010
Liver cancer consists of two main types—hepatocellular carcinoma (HCC) which accounts for about 60% of cases, and intrahepatic bile duct cholangiocarcinoma (ICC), which accounts for about 20%. The liver is one of the less common cancer sites, about 0.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dietary patterns among Afghan adults and their associations with overweight and obesity: a cross-sectional study in Kandahar, Afghanistan

open access: yesBMC Public Health
Background Although obesity is on the rise in Afghanistan, to date no studies have investigated associations with diet and dietary patterns. Therefore, the present study aimed to assess the different dietary patterns consumed among Afghan adults living ...

Methylglyoxal-Derived Nucleoside Adducts Drive Vascular Dysfunction in a RAGE-Dependent Manner

open access: yesAntioxidants
Diabetic kidney disease (DKD) is a leading cause of death in patients with diabetes. An early precursor to DKD is endothelial cell dysfunction (ECD), which often precedes and exacerbates vascular disease progression.
