GV1001 reduces neurodegeneration and prolongs lifespan in mouse model of Alzheimer’s disease

A brand new analysis paper titled “GV1001 reduces neurodegeneration and prolongs lifespan in 3xTg-AD mouse mannequin by way of anti-aging results” has been published in Growing older.

GV1001, which mimics the exercise of human telomerase reverse transcriptase, protects neural cells from amyloid beta (Aβ) toxicity and different stressors by way of extra-telomeric perform, as famous in our prior in vitro research. As per a current part II scientific trial, it improves cognitive perform in sufferers with reasonable to extreme dementia. Nevertheless, the underlying protecting mechanisms stay unclear.

On this new research, researchers Hyun-Hee Park, Hyuk Sung Kwon, Kyu-Yong Lee, Ye Eun Kim, Jeong-Woo Son, Na-Younger Choi, Myung-Hoon Han, Dong Woo Park, Sangjae Kim, and Seong-Ho Koh from Hanyang College Guri Hospital, Hanyang College Graduate Faculty of Biomedical Science and Engineering and Teloid Inc. aimed to analyze the consequences of GV1001 on neurodegeneration, senescence, and survival in triple transgenic Alzheimer’s illness (AD) (3xTg-AD) mice.

” […] we hypothesized that GV1001 might need anti-aging results and enhance neurodegeneration and senescence in vivo as a attainable mechanism for its useful results on AD,” the researchers write.

GV1001 (1 mg/kg) was subcutaneously injected into previous 3xTg-AD mice thrice per week till the endpoint for sacrifice, and survival was analyzed. Magnetic resonance imaging (MRI) and Prussian blue staining (PBS) had been carried out to guage entry of GV1001 entrance into the mind.

Various molecular research had been carried out to analyze the impact of GV1001 on neurodegeneration and cellular senescence in AD mannequin mice, with a specific concentrate on BACE, amyloid beta1-42 (Aβ1-42), phosphorylated tau, quantity of dentate gyrus, β-galactosidase constructive cells, telomere size, telomerase exercise, and aging-associated proteins.

GV1001 crossed the blood-brain barrier, as confirmed by assessing the standing of ferrocenecarboxylic acid-conjugated GV1001 utilizing magnetic resonance imaging and PBS. GV1001 elevated the survival of 3xTg-AD mice. It decreased BACE and Aβ1-42 ranges, neurodegeneration (i.e., lowered CA1, CA3 and dentate gyrus quantity, decreased ranges of senescence-associated β-galactosidase constructive cells, and elevated telomere size and telomerase exercise), and ranges of aging-associated proteins.

“We propose that GV1001 exerts anti-aging results in 3xTg-AD mice by lowering neurodegeneration and senescence, which contributes to improved survival,” the researchers write in conclusion.
