Between utopia and tragedy: the convergence of Faustian motif of “homunculus” and the key images of the novel “Doctor Zhivago” by B. Pasternak

open access: yesНеофилология, 2023
The purpose of study is to identify the semantic and figurative parallels of the second part of Goethe’s “Faust” and B.L. Pasternak’s novel “Doctor Zhivago”.

Homological properties of persistent homology

open access: yesJournal of Algebra and Its Applications
In this paper, we investigate to what extent persistent homology benefits from the properties of a homology theory. We show that persistent homology benefits from a Mayer–Vietoris sequence and a long exact sequence for a pair if one works with graded persistence modules.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

The establishment of a GPD1L knockout human embryonic stem cell line (WAe009-A-80) using the CRISPR/Cas9 system

open access: yesStem Cell Research
The GPD1L gene is located on 3p22.3. It encodes the glycerol phosphate dehydrogenase 1-like protein with homology to glycerol phosphate dehydrogenase (GPD1L), but the function of this enzyme is unclear.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Therapeutic potential of 20-Hydroxyecdysone in pulmonary arterial hypertension: involvement of Mas receptor and PI3K–Akt pathway

open access: yesCellular & Molecular Biology Letters
Background 20-Hydroxyecdysone (20E), a natural polyhydroxylated steroid found in various edible plants, exhibits diverse pharmacological effects. Pulmonary arterial hypertension (PAH) remains challenging to treat owing to its multifactorial pathogenesis.

The lipase gene family

open access: yesJournal of Lipid Research, 2002
Development of the lipase gene family spans the change in science that witnessed the birth of contemporary techniques of molecular biology. Amino acid sequencing of enzymes gave way to cDNA cloning and gene organization, augmented by in vitro expression ...

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

open access: yes, 2003
The present paper gives a description and philosophical analysis of the conceptual variation in the homology concept. It is argued that different homology are concepts used in evolutionary and comparative biology, in developmental biology, and in ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
