Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Nup133 Is Required for Proper Nuclear Pore Basket Assembly and Dynamics in Embryonic Stem Cells
Cell Reports, 2018 Summary: Nup133 belongs to the Y-complex, a key component of the nuclear pore complex (NPC) scaffold. Studies on a null mutation in mice previously revealed that Nup133 is essential for embryonic development but not for mouse embryonic stem cell (mESC ...

Nuclear Pore Proteins in Regulation of Chromatin State
Cells, 2019 Nuclear pore complexes (NPCs) are canonically known to regulate nucleocytoplasmic transport. However, research efforts over the last decade have demonstrated that NPCs and their constituent nucleoporins (Nups) also interact with the genome and perform ...

Diffusion Pore Imaging by Hyperpolarized Xenon-129 Nuclear Magnetic Resonance [PDF]
arXiv, 2012 Nuclear magnetic resonance (NMR) diffusion measurements are widely used to derive parameters indirectly related to the microstructure of biological tissues and porous media. However, a direct imaging of cell or pore shapes and sizes would be of high interest.

Interactome Mapping Reveals the Evolutionary History of the Nuclear Pore Complex
PLoS Biology, 2016 The nuclear pore complex (NPC) is responsible for nucleocytoplasmic transport and constitutes a hub for control of gene expression. The components of NPCs from several eukaryotic lineages have been determined, but only the yeast and vertebrate NPCs have ...

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Molecular genetics of oogenesis in Drosophila melanogaster [PDF]
Invertebrate Survival Journal, 2004 Gonadal development requires complex differentiation programs leading to the production offunctional female and male gametes. Upon fertilization, while the male germ cell contributes to thenewly formed zygote only its genetic material, the female germ ...

Effect of inhomogeneous surface relaxivity, pore geometry and internal field gradient on NMR logging:exact and perturbative theories and numerical investigations [PDF]
arXiv, 2009 Nuclear magnetic resonance is widely used as a probe of pore geometry and fluid composition in well logging. One of the critical assumptions often made is that the diffusion of fluid molecules is sufficiently fast to warrant the condition for direct mapping between the surface-enhanced relaxation rate and the pore geometry.
