  • Publication number: 20240124869
    Abstract: The invention pertains to an ex vivo method for increasing expression of at least one of gamma globin 1 (HBG1) and 2 (HBG2). The method can be used for the treatment or prevention of a haemoglobinopathy. The method comprises a step of introducing a first and a second site-specific endonuclease into a cell, wherein the first and second site-specific endonuclease generate a first and a second double stranded break in a chromosome, thereby generating a first, an intervening second and a third chromosomal fragment, wherein i) the first fragment comprises an beta globin locus control region (LCR) a functional fragment thereof; and ii) the third fragment comprises a sequence encoding at least one of HBG1 and HBG2. The length of the second intervening fragment is at least about 5 kb, and wherein joining the first fragment to the third fragment results in operably linking the beta globin LCR to the sequence encoding at least one of HBG1 and HBG2, thereby increasing at least one of HBG1 and HBG2 protein expression.

  • Publication number: 20240093288
    Abstract: The invention pertains to method for ribosome profiling at a single cell resolution. The method comprises the steps of i) lysing a single cell; ii) digesting the RNA with a ribonuclease, thereby generating an ribosome footprint containing RNA molecules that are protected against digestion; iii) Inactivating the ribonuclease and releasing the RNA molecules from the ribosomes; iv) end repairing the released RNA; v) constructing an RNA library from the end-repaired RNA molecules; vi) size selecting part of the prepared RNA library for fragments having an insert size of about 20-40 nucleotides; vii) sequencing the size selected RNA library; and viii) determining the translatome of the single cell.

  • Publication number: 20220088052
    Abstract: The present invention relates to novel treatments for treating cardiac disease involving fibro-fatty replacement, such as arrhythmogenic cardiomyopathy, atrial fibrillation, myocardial infarction and dilated cardiomyopathy. Such cardiac diseases can e.g. be caused by a mutation in a desmosomal protein such as plakophilin-2 (PKP2). The invention provides for agents for use in the prevention or treatment of such cardiac diseases, wherein the agent is at least one of: a) an agent that causes a reduction in expression in at least one TFAP2 subtype; and, b) an agent that causes a reduction in TFAP2-induced transcription. More preferably the agent is at least one of: a) an inhibitor of TFAP2; and, b) an agent that causes an increase in expression of PKP2.
