Abstract: The present invention relates to the use of an inhibitor of Rad18 expression or activity, in treating a tumor or in sensitizing a patient affected with a tumor, to a treatment with an antineoplastic agent that is a DNA damaging chemotherapeutic agent so to both reduce the self renewal of cancer stem cells and increase the DNA damage response thus boosting apoptotic cell death.

Abstract: The use of Dub3 protein, a nucleic acid molecule coding for the protein, or an inhibitor of the activity and/or of the expression of the protein for modulating cell differentiation.

Abstract: An isolated antibody specifically binding the C-terminus part of the MCM9 protein, the C-terminus part of the MCM9 protein is one of the following sequences: the amino acids sequence from the position 391 to the position 1143 of the MCM9 proteins of the sequence as set forth in SEQ ID NO: 2 or 16, or the amino acids sequence from the position 391 to the position 1143 of the MCM9 protein of the sequence as set forth in SEQ ID NO: 8.

Abstract: The use of the human or animal MCM9 gene, or parts of the gene, or transcripts thereof, or antisense nucleic acids able to hybridize with part of the gene or transcripts, or silencing RNA derived from parts of the transcripts and able to repress the MCM9 gene, or proteins or peptidic fragments translated from the transcripts, or antibodies directed against the proteins or peptidic fragments, for the preparation of a pharmaceutical composition for the treatment of a human or animal pathology linked to a dysfunction of the expression of the MCM9 gene, or of human or animal cancers.

Abstract: The use of the human or animal MCM8 gene coding for a DNA helicase, or parts of the gene, or transcripts thereof, or antisense nucleic acids able to hybridize with part of the transcripts, or silencing RNA derived from parts of the transcripts and able to repress the MCM8 gene, or proteins or peptidic fragments translated from the transcripts, or antibodies directed against the proteins or peptidic fragments for the preparation of a pharmaceutical composition for the treatment of a human or animal pathology linked to a dysfunction of the expression of the MCM8 gene, or of human or animal cancers.

Abstract: The present invention relates to the use of a peptidic sequence which comprises or is constituted of a peptidic chain of at least contiguous amino acids selected from the amino acid sequence SEQ ID NO: 4, SEQ ID NO: 4 being delimited by the amino acid in position 76 and by the amino acid in position 160 of SEQ ID NO: 2 (human Geminin), provided that, if present, the flanking regions of the peptidic chain in the peptidic sequence are different from the flanking regions of the peptidic chain in SEQ ID NO: 2, for the preparation of a drug intended for the treatment or prevention of pathologies implying pathological DNA replication and/or differentiation disorders, or disturbance of the cellular proliferation/differentiation balance.
