Mitochondria modified by a targeting protein, according to one embodiment of the present invention, can be effectively delivered to a target. In addition, when a protein of interest bound to the modified mitochondria is delivered into a cell, various activities can be exhibited. The modified mitochondria can effectively cause cancer tissue death, and thus can also be used as an anticancer agent. Furthermore, various activities are exhibited according to a protein of interest loaded on modified mitochondria, and thus the modified mitochondria can be applied in the treatment of various diseases. Additionally, a fusion protein comprising a protein of interest and a fusion protein comprising a targeting protein, according to one embodiment of the present invention, can be used in order to modify mitochondria. Moreover, mitochondria modified with the fusion proteins exhibits various effects in a target cell.

The present invention provides pharmaceutical compositions comprising membrane vesicles, including extracellular vesicles including those referred to as exosomes, loaded with an exogenous Phosphatase and tensin homolog (PTEN) inhibitor. Methods of treating neurological diseases, disorders or conditions using the extracellular vesicles are provided. Isolated extracellular vesicles loaded with an exogenous Phosphatase and tensin homolog (PTEN) inhibitor are provided as well.

The present invention provides oligomeric compounds. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount activity or expression of the target nucleic acid in a cell.

The present invention pertains to peptide-containing complexes/nanoparticles that are useful for delivering into a cell one or more mRNA (such as therapeutic mRNA, e.g., mRNA encoding a tumor suppressor protein).

The present application discloses a method of growing or proliferating nerve cells by contacting the cells with phosphatase and tensin homolog (PTEN) lipid phosphatase inhibiting peptide.

Various embodiments of the present invention are directed to the field of Oncology, and in particular, embodiments directed to a method of ameliorating, treating, or preventing a malignancy in a human subject wherein the steps of the method assist or boost the immune system in eradicating cancerous cells. Certain embodiments are directed to the field of human longevity and aging in a manner such that cancer is not contracted due to ameliorating, treating, or reducing aging by increasing the healthspan and lifespan of humans. In certain embodiments, administration of beneficial bacteria to an individual's microbiome that have been modified so as to produce effective amounts of desired compositions, compounds, agents, e.g. tomatidine, rapamycin, p53 protein, statins, etc., is employed to treat and prevent cancer and other age-related diseases.

Provided are an upstream Open Reading Frame (uORF) of a Phosphatase and Tensin homolog (PTEN) gene and a protein coded by the uORF. A potential ORF of 138 bases (45aa-uORF) in the 5UTR of the PTEN, coding an oligopeptide of 45 amino acids (named PTEN-45aa) plays an important role in the development and progression progress of tumors. Further provided are a new diagnostic and therapeutic method and a drug screening platform for PTEN expression regulation related diseases, in particular neuroglioma. Also provided is a polypeptide for treatment of PTEN expression regulation related diseases.

Disclosed are novel modified viruses comprising recombinant PTEN-Long and methods of using the same for treating cancer.

The present application discloses a method of growing or proliferating nerve cells by contacting the cells with phosphatase and tensin homolog (PTEN) lipid phosphatase inhibiting peptide.

Self-delivering PTEN RNA and methods of reducing PTEN expression are provided herein. Also provided are methods of treating spinal cord injury (SCI) and other neurotrauma with PTEN sdRNA.
