Long non-coding rna as therapeutic target in cardiac disorders and cardiac regeneration

A method for treating a cardiac disorder in a subject, the method comprising administering to the subject an effective amount of a nucleic acid molecule comprising:

• (i) a nucleotide sequence of SEQ ID NO:
• 1, 2, 3, 4 or 5, wherein the nucleic acid of—SEQ ID NO:
• 1, 2, 3, 4 or 5 increases viability and/or proliferation of cardiomyocytes,
• (ii) a nucleotide sequence which has an identity of at least 70%, at least 80%, at least 90% or at least 99% to any one of SEQ ID NO:
• 1, 2, 3, 4, or, 5, wherein the percentage of identity is determined over the whole length of SEQ ID NO:
• 1, 2, 3, 4 or 5, or
• (iii) a nucleotide sequence which is complementary to the nucleotide sequence of the nucleic acid molecule of (i) or (ii) over the whole length of the two sequences.
