MiRNA for treating head and neck cancer
The invention relates to the diagnostic and therapeutic uses of a miRNA-323, miRNA-342, miRNA-326, miRNA-371, miRNA-3157 and/or miRNA-345 molecule, an equivalent or a source thereof in a disease and condition associated with a squamous cell carcinoma such as head and neck cancer or a preneoplastic mucosal change.
1. A method for treating, reverting, and/or delaying a disease or a condition associated with a squamous cell carcinoma wherein the disease or condition is head and neck squamous cell carcinoma (HNSCC) by administering to a subject in need thereof a miRNA-323 molecule, isomiR, or a precursor thereof, or a composition comprising said miRNA-323 molecule, isomiR, or a precursor thereof
wherein said miRNA-323 molecule or isomiR comprises at least 6 nucleotides of the 7 nucleotides present in the seed sequence identified as SEQ ID NO: 11, 12, 61, 62, 63, 64, 65, 66, 67, 68, 69 and/or 70 and/or has at least 70% identity over SEQ ID NO: 22, 23, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221 222, 223, 224, 225, 226, 227, 228 and/or 229 and has a length from 6 to 40 nucleotides,
wherein the precursor is a precursor of a miRNA-323 molecule or isomiR and has at least 70% identity with SEQ ID NO:3 and/or 31 and has a length of at least 50 nucleotides.
2. A method for treating, reverting, and/or delaying a disease or a condition associated with a squamous cell carcinoma, wherein the disease or condition is head and neck squamous cell carcinoma (HNSCC) by administering to a subject in need thereof a miRNA-323 and/or miRNA-342 molecule, isomiR, or a precursor thereof, or a composition comprising said miRNA-323 and/or miRNA-342 molecule, isomiR, or a precursor thereof
wherein said miRNA-323 molecule or isomiR comprises at least 6 nucleotides of the 7 nucleotides present in the seed sequence identified as SEQ ID NO: 11, 12, 61, 62, 63, 64, 65, 66, 67, 68, 69 and/or 70 and/or has at least 70% identity over SEQ ID NO: 22, 23, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221 222, 223, 224, 225, 226, 227, 228 and/or 229 and has a length from 6 to 40 nucleotides,
wherein said miRNA-342 molecule or isomiR comprises at least 6 of the 7 nucleotides present in the seed sequence identified as SEQ ID NO: 14, 15, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98 and/or 99 and/or has at least 70% identity over SEQ ID NO: 25, 26, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 272, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, 288, 15 289, 290, 291, 292, 293, 294, 295, 296, 297, 298, 299, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 311, 312, 313, 314, 315, 316, 317 and/or 318 and has a length from 6 to 40 nucleotides,
wherein the precursor of a miRNA-342 molecule or isomiR has at least 70% identity with SEQ ID NO:5 and/or 33 and has a length of at least 50 nucleotides,
wherein the precursor of a miRNA-323 molecule or isomiR has at least 70% identity with SEQ ID NO:3 and/or 31 and has a length of at least 50 nucleotides.
