Involvement of Lamin B1 Reduction in Accelerated Cellular Senescence during Chronic Obstructive Pulmonary Disease Pathogenesis

open access: yesJournal of Immunology, 2019
Downregulation of lamin B1 has been recognized as a crucial step for development of full senescence. Accelerated cellular senescence linked to mechanistic target of rapamycin kinase (MTOR) signaling and accumulation of mitochondrial damage has been ...

Cyclin B1 is essential for mitosis in mouse embryos, and its nuclear export sets the time for mitosis

open access: yesJournal of Cell Biology, 2018
There is remarkable redundancy between the Cyclin–Cdk complexes that comprise the cell cycle machinery. None of the mammalian A-, D-, or E-type cyclins are required in development until implantation, and only Cdk1 is essential for early cell divisions ...

Hidden-flavour four-quark states in the charm and bottom region

open access: yes
We discuss the spectrum and the internal composition of ground and excited four-quark states in the charm and bottom energy region. To this end we extend previous calculations within the framework of the relativistic four-body Faddeev-Yakubovsky equation

Cyclin B2 can compensate for Cyclin B1 in oocyte meiosis I

open access: yesJournal of Cell Biology, 2018
Mammalian oocytes are arrested at the prophase of the first meiotic division for months and even years, depending on species. Meiotic resumption of fully grown oocytes requires activation of M-phase–promoting factor (MPF), which is composed of Cyclin B1 ...

¿Tienen historia los objetos? El encuentro de Pasteur y de Whitehead en un baño de ácido láctico

open access: yesIsegoría, 1995
Pretendo investigar de qué manera la metafísica de Whitehead puede arrojar alguna luz sobre un problema difícil de la historia social de las ciencias, la historicidad de las cosas, que hasta ahora no ha tenido solución satisfactoria.

Lamin B1 mapping reveals the existence of dynamic and functional euchromatin lamin B1 domains

open access: yesNature Communications, 2018
Lamins (A/C and B) are major constituents of the nuclear lamina (NL). Structurally conserved lamina-associated domains (LADs) are formed by genomic regions that contact the NL. Lamins are also found in the nucleoplasm, with a yet unknown function.
