Specific Urinary Metabolites in Malignant Melanoma

Medicina, 2019
Background and objectives: Melanin, which has a confirmed role in melanoma cell behaviour, is formed in the process of melanogenesis and is synthesized from tryptophan, L-tyrosine and their metabolites.

The Epidemiology of Primary Biliary Cholangitis in European Countries: A Systematic Review and Meta-Analysis

Canadian Journal of Gastroenterology and Hepatology, 2021
Background. Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease with wide ranges of reported incidence and prevalence. Aim. To map the incidence and prevalence of PBC in European countries from 2000 through 2020.

Mesenchymal Stem Cells in the Treatment of Human Spinal Cord Injury: The Effect on Individual Values of pNF-H, GFAP, S100 Proteins and Selected Growth Factors, Cytokines and Chemokines

Current Issues in Molecular Biology, 2022
At present, there is no effective way to treat the consequences of spinal cord injury (SCI). SCI leads to the death of neural and glial cells and widespread neuroinflammation with persisting for several weeks after the injury.

No association between nest-box size and breeding parameters in White-throated Dipper (Cinclus cinclus) [PDF]

Tichodroma
Nest-box size itself may influence clutch size. In this study, we analysed the variation in clutch size and brood size (number of fledglings at ringing) in relation to nest-box size in the White-throated Dipper.

Block-based Bayesian epistasis association mapping with application to WTCCC type 1 diabetes data [PDF]

Annals of Applied Statistics 2011, Vol. 5, No. 3, 2052-2077, 2011
Interactions among multiple genes across the genome may contribute to the risks of many complex human diseases. Whole-genome single nucleotide polymorphisms (SNPs) data collected for many thousands of SNP markers from thousands of individuals under the case--control design promise to shed light on our understanding of such interactions. However, nearby

Electrochemical SNP detection [PDF]

Nucleic Acids Symposium Series, 2006
Detection of mismatched base on a DNA duplex, which is important for the search of the heterozygote, achieved by the comparison with the reactivity of ferrocenylcarbodiimide (1) developed by our group. Mismatched thymine base on the 30-meric DNA duplex as a model of SNPs in lipoprotein lipase (LPL) gene, could react with 1 in 20 mM borate buffer (pH 8 ...

MET and NF2 alterations confer primary and early resistance to first‐line alectinib treatment in ALK‐positive non‐small‐cell lung cancer

Molecular Oncology, EarlyView.
Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

Model-based clustering for identifying disease-associated SNPs in case-control genome-wide association studies [PDF]

, 2018
Genome-wide association studies (GWASs) aim to detect genetic risk factors for complex human diseases by identifying disease-associated single-nucleotide polymorphisms (SNPs). The traditional SNP-wise approach along with multiple testing adjustment is over-conservative and lack of power in many GWASs.

Estimation of the covariance structure from SNP allele frequencies [PDF]

arXiv, 2022
We propose two new statistics, V and S, to disentangle the population history of related populations from SNP frequency data. If the populations are related by a tree, we show by theoretical means as well as by simulation that the new statistics are able to identify the root of a tree correctly, in contrast to standard statistics, such as the observed ...

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.
