Medical application of ubiquitin-specific proteases USP 7 to treating aging and related diseases

The invention provides application of ubiquitin-specific proteases USP7 to preparing drugs for treating aging and related diseases. The amino acid sequence of the USP7 is shown as SEQ. NO.2. Accordingto the application of the ubiquitin-specific proteases USP7 to preparing the drugs for treating aging and related diseases, the USP7 is activated to avoiding degradation of telomere proteins and damage of telomeres, particularly degradation of telomere proteins in environmental stress states such as radiation damage or oxidative stress., and meanwhile, avoid telomere damage and shortening, tissueand organ aging and related diseases caused by pressurized or stressed anaerobic states; expression and enzyme activity of the USP7 is inhibited to prevent protecting effects of the USP7 on the telomere proteins and the telomeres, to lead to telomere shortening and damage response, and further to cause proliferation and growth inhibition, aging and death of tumor cells and inhibit generation, development, growth, infiltration and metastasis of tumor. The USP7 can be applied to preparing drugs for preventing and treating telomere function related diseases and provide new anti-aging thoughts and methods.

Application of ubiquitin-specific protease 8 in regulation and breeding of Hu mutton

The invention relates to the application of ubiquitin-specific protease 8 (USP8) in regulating the meat quality and breeding of Hu mutton. Experiments have found that USP8 can affect the eating quality of Hu sheep muscle. The higher the expression level of USP8, the better the eating quality of Hu sheep. Therefore, Hu sheep with good meat quality can be selected as breeding sheep by screening the expression level of USP8. The invention clarifies that USP8 has an inhibitory effect on the early differentiation process of muscle satellite cells, provides a basic theoretical basis for the further protection and breeding of Hu sheep breeds, and also provides some references and technical reserves for the future directional selection of new strains .

Use of usp7 inhibitors for the treatment of acute myeloid leukemia (AML)

Resistance of acute myeloid leukemia (AML) cells to DNA damaging therapeutic agents is dependent on CHK1 protein levels. Here, the inventors demonstrate that in AML, CHK1 protein stability relies on the expression and activity of Ubiquitin Specific Protease 7 (USP7). CHK1 and USP7 levels are positively correlated in AML cell lines and primary patient specimens with high CHK1 protein levels. USP7 associates with CHK1, leading to its stabilization by deubiquitinylation, and this association is enhanced in response to cytarabine treatment. Pharmacological or RNA interference-mediated inhibition of USP7 significantly reduced AML proliferation in vitro and in vivo, and increased AML cell death. It is important to note that USP7 inhibition synergized with cytarabine to kill AML cell lines. This is also the case in primary patient specimens with high CHK1 levels. Transcriptomic dataset analyses revealed that a USP7 gene signature is highly enriched in cells from AML patients at relapse, as well as in residual blasts from Patient Derived Xenograft (PDX) models treated with clinically relevant doses of cytarabine, strongly suggesting a relationship between USP7 expression and resistance to therapy. Finally, single cell analysis from AML patient at relapse versus diagnosis showed that a gene signature of the pre-existing subpopulation responsible for relapse is enriched in transcriptomes of patients with high USP7 level. Altogether, these data demonstrate that USP7 is a master regulator of CHK1 protein kinase in AML cells, and represents both a marker of resistance to chemotherapeutic treatments, as well as a potential therapeutic target to overcome treatment resistance.
