Sexual dimorphism in the width of the mouse synaptonemal complex [PDF]

open access: yesJournal of Cell Science, 2018
ABSTRACT Sexual dimorphism has been used to describe morphological differences between the sexes, but can be extended to any biologically related process that varies between males and females. The synaptonemal complex (SC) is a tripartite structure that connects homologous chromosomes in meiosis.

Reconstructing the Stem Leydig Cell Niche via the Testicular Extracellular Matrix for the Treatment of Testicular Leydig Cell Dysfunction

open access: yesAdvanced Science, Volume 12, Issue 2, January 13, 2025.
Graphical abstract showing the mechanism by which dTECM‐SLC‐based therapy ameliorates testicular LC dysfunction. Local injection of dTECM‐SLC into the testicular interstitium. dTECM creates a favorable microenvironment for SLC proliferation and differentiation.

A meiotic mystery in experimental hybrids of the eastern mole vole (Ellobius tancrei, Mammalia, Rodentia)

open access: yesВавиловский журнал генетики и селекции, 2019
Chromosomal rearrangements can lead to the formation of new stable karyotypes, nevertheless changing the architectonics of the nucleus. The differences in locations might promote Robertsonian (Rb) translocations and encourage meiotic drive in favour of ...

Structural analysis of the human SYCE2–TEX12 complex provides molecular insights into synaptonemal complex assembly [PDF]

open access: yesOpen Biology, 2012
The successful completion of meiosis is essential for all sexually reproducing organisms. The synaptonemal complex (SC) is a large proteinaceous structure that holds together homologous chromosomes during meiosis, providing the structural framework for ...

Decomposition Complexes [PDF]

open access: yesarXiv, 2013
We introduce decomposition complexes of posets, which generalize order complexes. The main advantage of our construction is that decomposition complexes are closed under taking products. Other special instances of this theory include nested set complexes as well as Bergman complexes.

Complex Intersection Bodies [PDF]

open access: yes, 2012
We introduce complex intersection bodies and show that their properties and applications are similar to those of their real counterparts. In particular, we generalize Busemann's theorem to the complex case by proving that complex intersection bodies of symmetric complex convex bodies are also convex.

TRIP13: A promising cancer immunotherapy target

open access: yesCancer Innovation, Volume 3, Issue 6, December 2024.
Thyroid hormone receptor interactor 13 (TRIP13) inhibition presents a promising avenue for immunotherapy against tumors. Administration of DCZ0415 to immunocompetent myeloma models resulted in an upregulation of immune cells infiltrated in the tumor microenvironment, suggesting the immunotherapeutic potential of TRIP13 inhibition.

Mixing and Matching Chromosomes during Female Meiosis

open access: yesCells, 2020
Meiosis is a key event in the manufacturing of an oocyte. During this process, the oocyte creates a set of unique chromosomes by recombining paternal and maternal copies of homologous chromosomes, and by eliminating one set of chromosomes to become ...

The role and mechanism of NAT10‐mediated ac4C modification in tumor development and progression

open access: yesMedComm, Volume 5, Issue 12, December 2024.
RNA modification is a critical area of study within epigenetics, profoundly influencing the biological functions of tumors. Among these modifications, N4‐acetylcytidine (ac4C) stands out as the sole acetylation modification found in eukaryotic RNA. This modification is catalyzed by N‐acetyltransferase 10 (NAT10).

Matching trees for simplicial complexes and homotopy type of devoid complexes of graphs [PDF]

open access: yesarXiv, 2015
We generalize some homotopy calculation techniques such as splittings and matching trees that are introduced for the computations in the case of the independence complexes of graphs to arbitrary simplicial complexes, and exemplify their efficiency on some simplicial complexes, the devoid complexes of graphs, which are simplicial complexes parametrized ...
