Problems solved by technology

This is a major disadvantage, as the analysis is limited to a specific tissue and may miss ongoing roles in other tissues
Furthermore, the use of biomarkers to specifically differentiate senescent from non-senescent cells in human tissues remains a controversial issue
Therefore, there is an unmet need for novel novel biomarkers and diagnostics to detect senescent cells

Embodiment 1

[0273] 1. Materials and Methods

[0274] 1.1. Mice manipulation and serum sampling

[0275] p16-3MR (Demaria et al, 2014, Developmental Cell 31:722-733) mice were housed and housed at the AALAC-accredited Buck Institute for Research on Aging (Novato, CA) in the facility. 10 to 12 weeks old p16-3MR male mice were used in the experiment. The mice were divided into 4 groups with 3 mice in each group. In group A, control mice were injected with PBS. In group B, mice were treated with ganciclovir (GCV) (Sigma-Aldrich) in PBS for 5 consecutive days. In group C, mice were treated with doxorubicin hydrochloride (Sigma-Aldrich) in PBS. In group D, mice were first treated with doxorubicin and then GCV 10 days later. Mice were intraperitoneally injected with 10 mg / kg doxorubicin hydrochloride, and injected with GCV dissolved in PBS at a concentration of 25 mg / kg every day for 5 consecutive days. Four days after the last GCV administration, animals were euthanized with CO2 and bled...

Mice were divided into 4 groups, 8 in each group, 5 females and 3 males. In group A, control mice were injected with PBS. In group B, mice were treated with ganciclovir (GCV) (Sigma-Aldrich) in PBS for 5 consecutive days. In group C, mice were treated with doxorubicin hydrochloride (Sigma-Aldrich) in PBS.

Abstract

The present invention provides a method of detecting senescent cells or diagnosing cellular senescence in a subject wherein the level of one or more selected mi RNAs is quantified in a sample from said subject.

Description

[0001] This invention was made with US Government support under NIH Grant No. P01-AG017242. The US Government has certain rights in this invention. [0002] The present invention provides a method for detecting senescent cells or diagnosing cellular senescence in a subject, specifically an in vitro method, wherein the level of one or more selected miRNAs in a sample from said subject to quantify. Background technique [0003] Cellular senescence is a stable form of cell cycle arrest, a mechanism that limits the proliferative potential of cells. Senescence responses can be triggered in multiple cell types in response to different cellular stresses. It is a potent barrier to tumorigenesis and contributes to the cytotoxicity of certain anticancer drugs. Although senescence limits tumorigenesis and tissue damage in a cell-autonomous manner, senescent cells can induce inflammation, tissue aging and destruction, and promote tumorigenesis and metastasis in a cell-nonautonomous man...
