The Molecular Structure and Role of Humanin in Neural and Skeletal Diseases, and in Tissue Regeneration

open access: yesFrontiers in Cell and Developmental Biology, 2022
Humanin (HN) belongs to a member of mitochondrial-derived peptides (MDPs) which are encoded by mitochondrial genes. HN shares sequence homology with thirteen HN-like proteins, named MTRNR2L1 to MTRNR2L13, which encompass 24–28 amino acid residues in ...

Effects of zinc oxide and calcium–doped zinc oxide nanocrystals on cytotoxicity and reactive oxygen species production in different cell culture models [PDF]

open access: yesRestorative Dentistry & Endodontics, 2020
ObjectivesThis study aimed to synthesize nanocrystals (NCs) of zinc oxide (ZnO) and calcium ion (Ca2+)-doped ZnO with different percentages of calcium oxide (CaO), to evaluate cytotoxicity and to assess the effects of the most promising NCs on ...

The PDGF/VEGF Receptor Controls Blood Cell Survival in Drosophila

open access: yes, 2019
The Drosophila PDGF/VEGF receptor (PVR) has known functions in the guidance of cell migration. We now demonstrate that during embryonic hematopoiesis, PVR has a role in the control of antiapoptotic cell survival.

Do You Remember Mitochondria?

open access: yesFrontiers in Physiology, 2020
Dementia is one among the consequences of aging, and amnesia is often one of the most common symptoms. The lack of memory, as a consequence of both “healthy” aging or neurodegenerative conditions, such as in Alzheimer’s disease, has a dramatic impact on ...

Reduced hippocampal neurogenesis in R6/2 transgenic Huntington's disease mice

open access: yesNeurobiology of Disease, 2005
We investigated whether cell proliferation and neurogenesis are altered in R6/2 transgenic Huntington's disease mice. Using bromodeoxyuridine (BrdU), we found a progressive decrease in the number of proliferating cells in the dentate gyrus of R6/2 mice ...

AKT signaling mediates IGF-I survival actions on otic neural progenitors [PDF]

open access: yes, 2012
Background: Otic neurons and sensory cells derive from common progenitors whose transition into mature cells requires the coordination of cell survival, proliferation and differentiation programmes.

BECLIN-1/BECN1 at the barrier: a gatekeeper of epithelial and endothelial homeostasis

open access: yesAutophagy Reports
Epithelial and endothelial barriers are essential for tissue homeostasis, protecting the body from environmental insults while regulating selective transport. The integrity of these barriers relies on dynamic intercellular junctions whose composition and

Studies on the role of Coronin 1 and the actin cytoskeleton in T cell signaling and survival [PDF]

open access: yes, 2009
Calcium ions (Ca2+) function as universal second messengers in most if not all eukaryotic cells, including the cells of the immunesystem. Ca2+ signals are required for the proper activation of lymphocytes, such as T-lymphocytes, their proliferation ...

BECLIN-1 is essential for the maintenance of gastrointestinal epithelial integrity by regulating endocytic trafficking, F-actin organization, and lysosomal function

open access: yesAutophagy Reports
Disrupted intestinal homeostasis and barrier function contribute to the development of diseases such as inflammatory bowel disease. BECLIN-1, a core component of two class III phosphatidylinositol 3 kinase complexes, has a dual role in autophagy and ...

Spatiotemporal evolution of early innate immune responses triggered by neural stem cell grafting [PDF]

open access: yes, 2012
INTRODUCTION: Transplantation of neural stem cells (NSCs) is increasingly suggested to become part of future therapeutic approaches to improve functional outcome of various central nervous system disorders. However, recently it has become clear that only
