Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Norms for Semantic Categories in the Croatian Language

open access: yesPsychological Topics, 2020
In this paper, norms for semantic categories used in Croatian everyday language are presented. We used the list of 64 categories from the norms in English language (Van Overschelde et al., 2004), and 2 categories were added to the list.

REALIZING HIGHER CLUSTER CATEGORIES OF DYNKIN TYPE AS STABLE MODULE CATEGORIES

open access: yesThe Quarterly Journal of Mathematics, 2012
26 pages. This paper supersedes withdrawn preprints math.RT/0610728 and math.RT/0612451 which based the computation of Calabi-Yau dimensions on an erroneous result.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Balanced Choices: Examining the Impact of Dietary Diversity on BMI, Health Risks, and Rising Rates of Obesity in Kenya

open access: yesObesities
The study examines the link between dietary diversity and BMI using data from Kenyan women aged 15–49. By exploring how dietary diversity affects BMI across various BMI categories, the study examines the demand for diet diversity and its impact on BMI ...

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

open access: yesMolecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

A Cellular Nerve for Higher Categories

open access: yesAdvances in Mathematics, 2002
The nerve functor from the category of small categories to the category of simplicial sets is full and faithful, and the image is described by a sheaf condition. Furthermore, the category of small categories has a closed model structure in which a functor is a weak equivalence if and only if the nerve is a weak equivalence of simplicial sets, and there
