Abstract: The present disclosure relates to a monoclonal antibody specifically binding to human Long Interspersed Element-1 ORF2 encoded protein (L1-ORF2p) obtained from hybridoma chA1, and derivatives and uses thereof, including for prediction of response of cancer patients to NNRTI treatments. It also relates to a method for early detection of cell transformation in pre-neoplastic tissues of a human subject, comprising detecting in cells of a pre-neoplastic tissue sample from said subject the expression of L1-ORF2p, wherein the expression of L1-ORF2p indicates the presence of cell transformation in said pre-neoplastic tissues. It also relates to a method for detecting progression of colon adenoma in a human subject suffering from colon adenoma, based on detection of an increase of L1-ORF2p expression.

Abstract: The invention relates to nucleic acids, vector constructs which allow the controlled activation and inhibition of retrotransposition of non-LTR retrotransposons. The methods of this invention are useful for preparing said nucleic acids and vector constructs and introducing them into cells.

Abstract: The inventors developed novel pseudotyped lentiviral vector particles comprising a morbillivirus fusion (F) protein and a mutated hemagglutinin (H) protein of the measles virus (MeV) or the Edmonton strain of the measles virus (MeVEdm), wherein the cytoplasmic portions of the F and the H protein are truncated, and wherein the amino acids necessary for receptor recognition in the H protein are mutated that it does not interact with CD46, SLAM and/or nectin-4 and further has a single chain antibody to a cell surface marker of hESCs and iPSCs at its ectodomain. In this invention, the single chain variable fragment (scFv) anti-cell surface marker coding sequence of the single chain antibody is fused to the coding sequence at the ectodomain of the H protein, wherein the single chain antibody is selected from the group consisting of CD30, EpCAM (CD326), CD9, Thy-1 (CD90), SSEA-3, SSEA-4, TRA-1-60 or TRA-1-81. The transduction according to the present invention does not interfere with the pluripotency, i.e.
