Abstract: Provided herein are compositions and methods for the multiplexed profiling of RNA and DNA modifications across transcriptomes and genomes, respectively. The methods combine molecular recognition of non-canonical features (e.g., base modifications, backbone modifications, lesions, and/or structural elements) of a target nucleic acid with a step of writing the information from this recognition event into the neighboring genetic sequence of the target nucleic acid using a barcode. The resultant barcoded nucleic acids are then converted into sequencing libraries and read by DNA/RNA sequencing methods. This step reveals the sequence of the barcode, which is correlated with the non-canonical feature in the target nucleic acid(s). The high throughput profiling methods described herein allow for identification and/or localization of one or more modifications in a target nucleic acid. The methods also allow for identification of the nature and location of several or all DNA/RNA modifications in parallel.

Abstract: Provided herein is a method of treating low turnover renal osteodystrophy in a subject being administered an agent that reduces bone turnover comprising measuring a level of one or more miRNAs in a sample from the subject. The miRNA being measured can include miRNA-30b, miRNA-30c, miRNA-125b and miRNA-155. Administration of the agent that reduces bone turnover can be stopped if the level of the one or more miRNAs measured is lower than a level of the one or more miRNAs measured in a control subject. Administration of the agent that reduces bone turnover can be continued if the level of the one or more miRNAs measured is not lower than a level of the one or more miRNAs measured in a control subject.

Abstract: Alternative splicing events in genes can lead to non-productive mRNA transcripts which in turn can lead to aberrant protein expression, and therapeutic agents which can target the alternative splicing events in genes can modulate the expression level of functional proteins in patients and/or inhibit aberrant protein expression. Such therapeutic agents can be used to treat a condition or disease caused by protein deficiency and/or mitochondrial function deficit.
