N-terminal acetylation of actin by NAA80 is essential for structural integrity of the Golgi apparatus
(Journal article; Peer reviewed, 2020)N-alpha-acetyltransferase 80 (NAA80) was recently demonstrated to acetylate the N-terminus of actin, with NAA80 knockout cells showing actin cytoskeleton-related phenotypes, such as increased formation of membrane protrusions ... -
The N-terminal sequence of tyrosine hydroxylase is a conformationally versatile motif that binds 14-3-3 proteins and membranes
(Peer reviewed; Journal article, 2014-01-09)Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the synthesis of catecholamine neurotransmitters, and a reduction in TH activity is associated with several neurological diseases. Human TH is regulated, among ... -
Na+ is shifted from the extracellular to the intracellular compartment and is not inactivated by glycosaminoglycans during high salt conditions in rats
(Journal article; Peer reviewed, 2022)Recently, studies have emerged suggesting that the skin plays a role as major Na+ reservoir via regulation of the content of glycosaminoglycans and osmotic gradients. We investigated whether there were electrolyte gradients ... -
NAA10 p.(D10G) and NAA10 p.(L11R) variants hamper formation of the NatA N-terminal acetyltransferase complex
(Journal article; Peer reviewed, 2020)The majority of the human proteome is subjected to N-terminal (Nt) acetylation catalysed by N-terminal acetyltransferases (NATs). The NatA complex is composed of two core subunits—the catalytic subunit NAA10 and the ribosomal ... -
NAA10 p.(N101K) disrupts N-terminal acetyltransferase complex NatA and is associated with developmental delay and hemihypertrophy
(Journal article; Peer reviewed, 2020)Nearly half of all human proteins are acetylated at their N-termini by the NatA N-terminal acetyltransferase complex. NAA10 is evolutionarily conserved as the catalytic subunit of NatA in complex with NAA15, but may also ... -
The native structure of annexin A2 peptides in hydrophilic environment determines their anti-angiogenic effects
(Peer reviewed; Journal article, 2015-03-13)The progression of aggressive cancer occurs via angiogenesis and metastasis makes these processes important targets for the development of anti-cancer agents. However, recent studies have raised the concern that selective ... -
The Natural Flavonoid Galangin Elicits Apoptosis, Pyroptosis, and Autophagy in Glioblastoma
(Peer reviewed; Journal article, 2019-09-27)Galangin (GG), a flavonoid, elicits a potent antitumor activity in diverse cancers. Here, we evaluated the efficacy of GG in the treatment of human glioblastoma multiforme (GBM) and investigated the molecular basis for its ... -
Natural killer cells in intracranial neoplasms: presence and therapeutic efficacy against brain tumours
(Peer reviewed; Journal article, 2014-01)Natural killer (NK) cells are lymphocytes that play an important role in anti-tumour immunity. Their potential against brain cancer has been demonstrated in vitro and in vivo, both as a direct anti-tumour agent and in ... -
Neoadjuvant chemotherapy in breast cancer-response evaluation and prediction of response to treatment using dynamic contrast-enhanced and diffusion-weighted MR imaging
(Peer reviewed; Journal article, 2011)Objective To explore the predictive value of MRI parameters and tumour characteristics before neoadjuvant chemotherapy (NAC) and to compare changes in tumour size and tumour apparent diffusion coefficient (ADC) during ... -
Neural Stem Cells of Parkinson's Disease Patients Exhibit Aberrant Mitochondrial Morphology and Functionality.
(Peer reviewed; Journal article, 2019-04-11)Summary Emerging evidence suggests that Parkinson's disease (PD), besides being an age-associated disorder, might also have a neurodevelopment component. Disruption of mitochondrial homeostasis has been highlighted as a ... -
Neuronal markers are expressed in human gliomas and NSE knockdown sensitizes glioblastoma cells to radiotherapy and temozolomide
(Peer reviewed; Journal article, 2011-12-20)Background: Expression of neuronal elements has been identified in various glial tumors, and glioblastomas (GBMs) with neuronal differentiation patterns have reportedly been associated with longer survival. However, the ... -
Neuropathy-related mutations alter the membrane binding properties of the human myelin protein P0 cytoplasmic tail
(Peer reviewed; Journal article, 2019-06-07)Schwann cells myelinate selected axons in the peripheral nervous system (PNS) and contribute to fast saltatory conduction via the formation of compact myelin, in which water is excluded from between tightly adhered lipid ... -
New lessons from an “old” drug: A proteomic study of anthracycline-induced apoptosis in acute myelogenous leukemia
(Doctoral thesis, 2007-12-18)Anthracyclines have been first line drugs for more than 3 decades in the treatment of acute myelogenous leukemia (AML). Even though the mechanism of action of anthracyclines has been extensively studied over the years, ... -
A new live-cell reporter strategy to simultaneously monitor mitochondrial biogenesis and morphology
(Peer reviewed; Journal article, 2015-11-24)Changes in mitochondrial amount and shape are intimately linked to maintenance of cell homeostasis via adaptation of vital functions. Here, we developed a new live-cell reporter strategy to simultaneously monitor mitochondrial ... -
A New Look at the Functional Organization of the Golgi Ribbon
(Peer reviewed; Journal article, 2019-08-21)A characteristic feature of vertebrate cells is a Golgi ribbon consisting of multiple cisternal stacks connected into a single-copy organelle next to the centrosome. Despite numerous studies, the mechanisms that link the ... -
A New Method for Isolation of Interstitial Fluid from Human Solid Tumors Applied to Proteomic Analysis of Ovarian Carcinoma Tissue
