Integrative approaches to protein homology search [PDF]

open access: yes, 2005
Alam I. Integrative approaches to protein homology search. Bielefeld (Germany): Bielefeld University; 2005.Many methods have been developed to search for homologous members of a protein family in databases, and the reliability of results and conclusions ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

The 'Role' a Concept Plays in Science - The Case of Homology [PDF]

open access: yes, 2001
This article tries to clarify the idea that a concept plays a certain role for a scientific field or a research program. The discussion is based on a case study of the homology concept in biology.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix

open access: yesFEBS Letters, EarlyView.
The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...

Simplicial methods and the homology of groups. [PDF]

open access: yes, 1997
PhDThis thesis generalizes the simplicial methods of defining derived functors and proves characterization theorems about them. In particular, we show that our methods also generalize an alternative way of defining derived functors, We use our ...

Covering homology

open access: yesAdvances in Mathematics, 2010
We introduce the notion of "covering homology" of a commutative ring spectrum with respect to certain families of coverings of topological spaces. The construction of covering homology is extracted from Bokstedt, Hsiang and Madsen's topological cyclic homology.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

open access: yesMolecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Analysis and Predictive Modeling of In Vitro Digestive Stability of Tea Polyphenols in 24 Tea Varieties

open access: yesFood Frontiers
Tea polyphenols (TP) constitute key functional components in tea leaves, yet their instability during human digestion limits absorption. This study selected 24 representative tea varieties to establish an in vitro dynamic digestion model, investigating ...

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

open access: yesMolecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...
