β‐galactosidase liên quan đến lão hóa là β‐galactosidase lysosome Dịch bởi AI Tập 5 Số 2 - Trang 187-195 - 2006

Tóm tắtLão hóa tái sinh hạn chế sự sinh sản của các tế bào soma được nuôi cấy và
có thể phản ánh sự lão hóa tế bào in vivo. Chỉ số sinh học được sử dụng phổ biến
nhất để xác định tế bào lão hóa và lão hóa là β‐galactosidase liên quan đến lão
hóa (SA‐β‐gal), được định nghĩa là hoạt động β‐galactosidase có thể phát hiện
được ở pH 6.0 trong các tế bào lão hóa, nhưng nguồn gốc của SA‐β‐gal và vai trò

Fat tissue, aging, and cellular senescence Tập 9 Số 5 - Trang 667-684 - 2010

SummaryFat tissue, frequently the largest organ in humans, is at the nexus of
mechanisms involved in longevity and age‐related metabolic dysfunction. Fat
distribution and function change dramatically throughout life. Obesity is
associated with accelerated onset of diseases common in old age, while fat
ablation and certain mutations affecting fat increase life span. Fat cells turn
over throughout t... hiện toàn bộ
Lifespan extension by conditions that inhibit translation in Caenorhabditis elegans Tập 6 Số 1 - Trang 95-110 - 2007
Malene Hansen, Stefan Taubert, Douglas K. Crawford, Nataliya Libina, Seung‐Jae Lee, Cynthia Kenyon
SummaryMany conditions that shift cells from states of nutrient utilization and
growth to states of cell maintenance extend lifespan. We have carried out a
systematic lifespan analysis of conditions that inhibit protein synthesis. We
find that reducing the levels of ribosomal proteins, ribosomal‐protein S6 kinase
or translation‐initiation factors increases the lifespan of Caenorhabditis
elegans. T... hiện toàn bộ
SIRT1 transgenic mice show phenotypes resembling calorie restriction Tập 6 Số 6 - Trang 759-767 - 2007

SummaryWe generated mice that overexpress the sirtuin, SIRT1. Transgenic mice
have been generated by knocking in SIRT1 cDNA into the β‐actin locus. Mice that
are hemizygous for this transgene express normal levels of β‐actin and higher
levels of SIRT1 protein in several tissues. Transgenic mice display some
phenotypes similar to mice on a calorie‐restricted diet: they are leaner than
littermate co... hiện toàn bộ
DNA damage response and cellular senescence in tissues of aging mice Tập 8 Số 3 - Trang 311-323 - 2009
Chunfang Wang, Diana Jurk, Mandy Maddick, Glyn Nelson, Carmen Martín-Ruiz, Thomas von Zglinicki
SummaryThe impact of cellular senescence onto aging of organisms is not fully
clear, not at least because of the scarcity of reliable data on the mere
frequency of senescent cells in aging tissues. Activation of a DNA damage
response including formation of DNA damage foci containing activated H2A.X
(γ‐H2A.X) at either uncapped telomeres or persistent DNA strand breaks is the
major trigger of cell ... hiện toàn bộ
A senescent cell bystander effect: senescence‐induced senescence Tập 11 Số 2 - Trang 345-349 - 2012
Glyn Nelson, James Wordsworth, Chunfang Wang, Diana Jurk, Conor Lawless, Carmen Martín-Ruiz, Thomas von Zglinicki
SummarySenescent cells produce and secrete various bioactive molecules including
interleukins, growth factors, matrix‐degrading enzymes and reactive oxygen
species (ROS). Thus, it has been proposed that senescent cells can damage their
local environment, and a stimulatory effect on tumour cell growth and
invasiveness has been documented. However, it was unknown what effect, if any,
senescent cells... hiện toàn bộ
Chronic senolytic treatment alleviates established vasomotor dysfunction in aged or atherosclerotic mice Tập 15 Số 5 - Trang 973-977 - 2016

Reduced oxygen tension attenuates differentiation capacity of human mesenchymal stem cells and prolongs their lifespan Tập 6 Số 6 - Trang 745-757 - 2007

SummaryMesenchymal stem cells (MSC) are capable of differentiating into bone,
fat, cartilage, tendon and other organ progenitor cells. Despite the abundance
of MSC within the organism, little is known about their in vivo properties or
about their corresponding in vivo niches. We therefore isolated MSC from spongy
(cancellous) bone biopsies of healthy adults. When compared with the surrounding

AbstractThe global population of individuals over the age of 65 is growing at an
unprecedented rate and is expected to reach 1.6 billion by 2050. Most older
individuals are affected by multiple chronic diseases, leading to complex drug
treatments and increased risk of physical and cognitive disability. Improving or
preserving the health and quality of life of these individuals is challenging
