The oligonucleotide compositions of the present invention make use of combinations of oligonucleotides. In one aspect, the invention features an oligonucleotide composition including at least 2 different oligonucleotides targeted to a target gene. This invention also provides methods of inhibiting protein synthesis in a cell and methods of identifying oligonucleotide compositions that inhibit synthesis of a protein in a cell.

Provided herein are compositions and methods for treating or preventing metabolic disorders. In particular, provided herein are compositions, methods, and uses of Cyclin-dependent Kinase 6 (CDK6) inhibitors for treating and preventing metabolic diseases (e.g., type II diabetes, obesity, metabolic syndrome, elevated blood pressure, cardiovascular diseases, elevated fasting plasma glucose, and high serum triglycerides).

A method of sensitizing cancer to immunotherapy in a subject in need thereof includes administering to the subject a therapeutically effective amount of a CdK5 inhibitor to suppress immune checkpoint PD-L1.

Kinases can be engineered to utilize an ATP analog that is not readily utilized by wild-type kinases by introducing a mutation in the ATP-binding pocket. However, application of this method has been limited by the membrane impermeability of the ATP analog. Provided herein are methods for in situ visualization of substrates of an analog-sensitive kinase, the method comprising a mild fixation step. Also provided herein are kits comprising a fixative, an ATP analog, and an agent for detecting the substrates modified by the ATP analog.

Compositions and methods for the detection and treatment of T1D are provided.

The present invention provides compositions for RNA interference and methods of use thereof. In particular, the invention provides small interfering RNAs (siRNAs) having modification that enhance the stability of the siRNA without a concomitant loss in the ability of the siRNA to participate in RNA interference (RNAi). The invention also provides siRNAs having modification that increase targeting efficiency. Modifications include chemical crosslinking between the two complementary strands of an siRNA and chemical modification of a 3 terminus of a strand of an siRNA. Preferred modifications are internal modifications, for example, sugar modification, nucleobase modification and/or backbone modifications. Such modifications are also useful, e.g., to improve uptake of the siRNA by a cell. Functional and genomic and proteomic methods are featured. Therapeutic methods are also featured.

The present invention relates to compositions and methods for detecting CDK4/6 response and resistance.

A product and process for extending the replicative capacity of metazoan somatic cells using targeted genetic amendments to abrogate inhibition of cell-cycle progression during replicative senescence and derive clonal cell lines for scalable applications and industrial production of metazoan cell biomass. An insertion or deletion mutation using guide RNAs targeting the first exon of the transcript encoding each protein is created using CRISPR/Cas9. Targeted amendments result in inactivation of p15 and p16 proteins which increases the proliferative capacity of the modified cell populations relative to their unaltered parental populations. Combining these amendments with ancillary telomerase activity from a genetic construct directing expression of a telomerase protein homolog from a TERT gene, increases the replicative capacity of the modified cell populations indefinitely. One application is to manufacture skeletal muscle for dietary consumption using cells from the poultry species Gallus gallus; another is from the livestock species Bos taurus.

The oligonucleotide compositions of the present invention make use of combinations of oligonucleotides. In one aspect, the invention features an oligonucleotide composition including at least 2 different oligonucleotides targeted to a target gene. This invention also provides methods of inhibiting protein synthesis in a cell and methods of identifying oligonucleotide compositions that inhibit synthesis of a protein in a cell.
