Described herein are compositions and methods for enhancing erythropoiesis in an individual in need thereof. Specifically agents that decrease the expression of Exosc10, such as inhibitory nucleic acid molecules, produce an increase in red blood cell production in the individual.

Described herein are methods of prolonging or reactivating organogenesis in a subject in need thereof (e.g., a subject that has impaired organ function such as a prematurely born infant). The methods comprise increasing the expression or activity of Lin28A or Lin28B proteins, inhibiting the expression or activity of let-7 family microRNAs, and/or inhibiting the expression or activity of Dis3L2 exonuclease.

A method of treating breast cancer is described, in which a peptide having cancer selective translocation function-doxoribicin conjugate is administered. The conjugate includes doxorubicin chemically linked to the N-terminus or C-terminus of a VEGF-binding protein transduction domain (VPTD) peptide represented as SEQ ID NO: 1, wherein the VPTD peptide and doxorubicin are linked to each other by a disulfide bond, and wherein the VPTD peptide binds specifically to vascular endothelial growth factor (VEGF) in tumor cells or tumor tissues.

Described herein are methods of prolong or reactivating organogenesis in a subject in need thereof (e.g., a subject that has impaired organ function such as a prematurely born infant). The methods comprises increasing the expression or activity of Lin28A or Lin28B proteins, inhibiting the expression or activity of let-7 family microRNAs, and/or inhibiting the expression or activity of Dis3L2 exonuclease.

Disclosed herein are compositions comprising one or more subgenomic Flavivirus RNA (sfRNA) elements and using those compositions in methods of improving mRNA transcript stability, improving mRNA transcript translation efficiency, enhancing gene therapy, and treating and/or preventing a disease or disorder.

The methods of the disclosure can be used to enrich a population of circular polyribonucleotides in a mixture of linear polyribonucleotides and circular polyribonucleotides.
