Stem cell-associated heterogeneity in Glioblastoma results from intrinsic tumor plasticity shaped by the microenvironment
(Peer reviewed; Journal article, 2019-04-16)The identity and unique capacity of cancer stem cells (CSC) to drive tumor growth and resistance have been challenged in brain tumors. Here we report that cells expressing CSC-associated cell membrane markers in Glioblastoma ... -
Stimulant treatment profiles predicting co-occurring substance use disorders in individuals with attention-deficit/hyperactivity disorder
(Peer reviewed; Journal article, 2019-02-05)Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of developing substance use disorders (SUDs) and nicotine dependence (ND). It remains unclear whether and how stimulant treatment may ... -
Stimulation-induced expression of immediate early gene proteins in the dorsal horn is increased in neuropathy
(Peer reviewed; Journal article, 2016-01)Background and aims: Peripheral neuropathic pain is described as a pain state caused by an injury or dysfunction of the nervous system, and could have clinical manifestations such as hyperalgesia, allodynia and spontaneous ... -
Stromal integrin α11 regulates PDGFR-β signaling and promotes breast cancer progression
(Peer reviewed; Journal article, 2019)Cancer-associated fibroblasts (CAFs) are key actors in modulating the progression of many solid tumors, such as breast cancer (BC). Herein, we identify an integrin α11/PDGFRβ–positive CAF subset displaying tumor-promoting ... -
Stromal integrin α11-deficiency reduces interstitial fluid pressure and perturbs collagen structure in triple-negative breast xenograft tumors
(Peer reviewed; Journal article, 2019-03-15)Background: Cancer progression is influenced by a pro-tumorigenic microenvironment. The aberrant tumor stroma with increased collagen deposition, contractile fibroblasts and dysfunctional vessels has a major impact on the ... -
Stromal integrin α11β1 affects RM11 prostate and 4T1 breast xenograft tumors differently
(Peer reviewed; Journal article, 2016-03-18)Purpose It has been implied that the collagen binding integrin α11β1 plays a role in carcinogenesis. As still relatively little is known about how the stromal integrin α11β1 affects different aspects of tumor development, ... -
Structural and biochemical characterization of Malaria parasites
(Doctoral thesis, 2021-09-17)The Apicomplexa phylum includes more than 6000 species, and some of them are pathogens of humans and animals of socio-economic importance. The most representative parasites are Plasmodium spp. and Toxoplasma gondii. ... -
Structural and biophysical characterization of transcription factor HNF-1A as a tool to study MODY3 diabetes variants
(Journal article; Peer reviewed, 2022)Hepatocyte nuclear factor 1A (HNF-1A) is a transcription factor expressed in several embryonic and adult tissues, modulating the expression of numerous target genes. Pathogenic variants in the HNF1A gene are known to cause ... -
Structural and thermodynamic insight into phenylalanine hydroxylase from the human pathogen Legionella pneumophila
(Peer reviewed; Journal article, 2013-08-19)Phenylalanine hydroxylase from Legionella pneumophila (lpPAH) has a major functional role in the synthesis of the pigment pyomelanin, which is a potential virulence factor. We present here the crystal structure of lpPAH, ... -
Structural aspects of nucleotide ligand binding by a bacterial 2H phosphoesterase
(Peer reviewed; Journal article, 2017-01-31)The 2H phosphoesterase family contains enzymes with two His-X-Ser/Thr motifs in the active site. 2H enzymes are found in all kingdoms of life, sharing little sequence identity despite the conserved overall fold and active ... -
Structural insights into Charcot–Marie–Tooth disease-linked mutations in human GDAP1
(Journal article; Peer reviewed, 2022)Charcot–Marie–Tooth disease (CMT) is the most common inherited peripheral polyneuropathy in humans, and its different subtypes are linked to mutations in dozens of different genes. Mutations in ganglioside-induced ... -
Structural mechanism for tyrosine hydroxylase inhibition by dopamine and reactivation by Ser40 phosphorylation
(Journal article; Peer reviewed, 2022)Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the biosynthesis of dopamine (DA) and other catecholamines, and its dysfunction leads to DA deficiency and parkinsonisms. Inhibition by catecholamines and ... -
Structural properties and peptide ligand binding of the capsid homology domains of human Arc
(Journal article; Peer reviewed, 2021)The activity-regulated cytoskeleton-associated protein (Arc) is important for synaptic plasticity and the normal function of the brain. Arc interacts with neuronal postsynaptic proteins, but the mechanistic details of its ... -
Structural similarities and functional differences clarify evolutionary relationships between tRNA healing enzymes and the myelin enzyme CNPase
(Peer reviewed; Journal article, 2017-05-16)Background: Eukaryotic tRNA splicing is an essential process in the transformation of a primary tRNA transcript into a mature functional tRNA molecule. 5′-phosphate ligation involves two steps: a healing reaction catalyzed ... -
Structure and dynamics of a human myelin protein P2 portal region mutant indicate opening of the β barrel in fatty acid binding proteins
(Peer reviewed; Journal article, 2018-06-25)Background: Myelin is a multilayered proteolipid sheath wrapped around selected axons in the nervous system. Its constituent proteins play major roles in forming of the highly regular membrane structure. P2 is a myelin-specific ... -
Structure and function of an atypical homodimeric actin capping protein from the malaria parasite
(Journal article; Peer reviewed, 2022)Apicomplexan parasites, such as Plasmodium spp., rely on an unusual actomyosin motor, termed glideosome, for motility and host cell invasion. The actin filaments are maintained by a small set of essential regulators, which ... -
