PeptideShaker Online: A User-Friendly Web-Based Framework for the Identification of Mass Spectrometry-Based Proteomics Data
(Journal article; Peer reviewed, 2021)Mass spectrometry-based proteomics is a high-throughput technology generating ever-larger amounts of data per project. However, storing, processing, and interpreting these data can be a challenge. A key element in simplifying ... -
Loss of COPZ1 induces NCOA4 mediated autophagy and ferroptosis in glioblastoma cell lines
(Journal article; Peer reviewed, 2021)Dysregulated iron metabolism is a hallmark of many cancers, including glioblastoma (GBM). However, its role in tumor progression remains unclear. Herein, we identified coatomer protein complex subunit zeta 1 (COPZ1) as a ... -
Annexin A2 binds the internal ribosomal entry site of c-myc mRNA and regulates its translation
(Journal article; Peer reviewed, 2021)The expression and localization of the oncoprotein c-Myc is highly regulated at the level of transcription, mRNA transport, translation, as well as stability of the protein. We previously showed that Annexin A2 (AnxA2) ... -
A map of metabolic phenotypes in patients with myalgic encephalomyelitis/chronic fatigue syndrome
(Journal article; Peer reviewed, 2021)Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disease usually presenting after infection. Emerging evidence supports that energy metabolism is affected in ME/CFS, but a unifying metabolic ... -
1q21.1 distal copy number variants are associated with cerebral and cognitive alterations in humans
(Journal article; Peer reviewed, 2021)Low-frequency 1q21.1 distal deletion and duplication copy number variant (CNV) carriers are predisposed to multiple neurodevelopmental disorders, including schizophrenia, autism and intellectual disability. Human carriers ... -
Role of integrin α11β1 in breast cancer
(Doctoral thesis, 2021-09-24)Breast cancer cells are strongly influenced by a complex tumor microenvironment comprised of a diversity of stromal cells, including a heterogeneous population of cancer associated fibroblasts (CAFs), in addition to the ... -
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. ... -
Regulatory post-translational modifications and protein-protein interactions involved in function and proteostasis of aromatic amino acid hydroxylases
(Doctoral thesis, 2021-09-16)The non-heme iron and (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) dependent aromatic amino acid hydroxylases (AAAHs) family of enzymes include phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), and tryptophan ... -
The Pah-R261Q mouse reveals oxidative stress associated with amyloid-like hepatic aggregation of mutant phenylalanine hydroxylase
(Journal article; Peer reviewed, 2021)Phenylketonuria (PKU) is caused by autosomal recessive variants in phenylalanine hydroxylase (PAH), leading to systemic accumulation of L-phenylalanine (L-Phe) that may reach neurotoxic levels. A homozygous Pah-R261Q mouse, ... -
Instability in NAD+ metabolism leads to impaired cardiac mitochondrial function and communication
(Journal article; Peer reviewed, 2021)Poly(ADP-ribose) polymerase (PARP) enzymes initiate (mt)DNA repair mechanisms and use nicotinamide adenine dinucleotide (NAD+) as energy source. Prolonged PARP activity can drain cellular NAD+ reserves, leading to de-regulation ... -
RNA sequencing and proteomic profiling reveal different alterations by dietary methylmercury in the hippocampal transcriptome and proteome in BALB/c mice
(Journal article; Peer reviewed, 2021)Methylmercury (MeHg) is a highly neurotoxic form of mercury (Hg) present in seafood. Here, we recorded and compared proteomic and transcriptomic changes in hippocampus of male BALB/c mice exposed to two doses of MeHg. Mice ... -
Different glutamate sources and endogenous co-agonists activate extrasynaptic NMDA receptors on amacrine cells of the rod pathway microcircuit
(Journal article; Peer reviewed, 2021)The NMDA receptors (NMDARs) expressed by AII and A17 amacrine cells, the two main inhibitory interneurons of the rod pathway microcircuit in the mammalian retina, are exclusively extrasynaptic, activated by ambient levels ... -
Characterization of porphobilinogen deaminase mutants reveals that arginine-173 is crucial for polypyrrole elongation mechanism
(Journal article; Peer reviewed, 2021)Porphobilinogen deaminase (PBGD), the third enzyme in the heme biosynthesis, catalyzes the sequential coupling of four porphobilinogen (PBG) molecules into a heme precursor. Mutations in PBGD are associated with acute ... -
Metformin treatment response is dependent on glucose growth conditions and metabolic phenotype in colorectal cancer cells
(Journal article; Peer reviewed, 2021)Cancer cells exhibit altered metabolism, a phenomenon described a century ago by Otto Warburg. However, metabolic drug targeting is considered an underutilized and poorly understood area of cancer therapy. Metformin, a ... -
