1. A method for reducing or inhibiting cell proliferation in a human cancer cell comprising introducing into the cell an effective amount of at least one synthetic double-stranded RNA molecule of between 17 and 25 residues in length comprising a) an active strand comprising a sequence from 5′ to 3′
1. A method for reducing or inhibiting cell proliferation in a human cancer cell comprising introducing into the cell an effective amount of at least one synthetic double-stranded RNA molecule of between 17 and 25 residues in length comprising a) an active strand comprising a sequence from 5′ to 3′ that is identical to a mature human miRNA sequence, andb) a separate complementary strand whose sequence from 5′ to 3′ is 100% complementary to the active strand, wherein the mature miRNA sequence is selected from the group consisting of: miR-16, miR-96, miR-101, miR-105, miR-124, miR-142, miR-147, miR-206, or miR-346, wherein the complementary strand comprises a chemical modification at the 5′ end that enhances activity of the active strand. 2. The method of claim 1, further comprising identifying a cell or a patient having the cell as in need of reducing or inhibiting cell proliferation, wherein the cell is a cancer cell. 3. The method of claim 1, wherein the chemical modification is an NH2, biotin, an amine group, a lower alkylamine group, or an acetyl group. 4. The method of claim 1, wherein the synthetic double-stranded RNA molecule has a complementary strand that has a 5′ terminal nucleotide with a sugar modification. 5. The method of claim 4, wherein the sugar modification is 2′OMe. 6. The method of claim 1, wherein the mature miRNA sequence is miR-16. 7. The method of claim 1, wherein the mature miRNA sequence is miR-96. 8. The method of claim 1, wherein the mature miRNA sequence is miR-101. 9. The method of claim 1, wherein the mature miRNA sequence is miR-105. 10. The method of claim 1, wherein the mature miRNA sequence is miR-124. 11. The method of claim 1, wherein the mature miRNA sequence is miR-142. 12. The method of claim 1, wherein the mature miRNA sequence is miR-147. 13. The method of claim 1, wherein the mature miRNA sequence is miR-206. 14. The method of claim 1, wherein the mature miRNA sequence is miR-346. 15. A method for treating lung cancer in a human subject comprising administering to the subject an effective amount of one or more synthetic double-stranded miRNA molecules corresponding to human miR-124, miR-126, or miR-147, wherein the synthetic miRNA molecule is 17 to 30 residues in length and comprises: a) an active strand comprising a sequence of a mature human miRNA, andb) a separate strand comprising a sequence that is fully complementary to mature miRNA sequence and having at least one chemical modification at the 5′ end that enhances the activity of the active strand. 16. The method of claim 15, wherein one of the synthetic double-stranded molecules corresponds to human miR-124. 17. The method of claim 15, wherein one of the synthetic double-stranded molecules corresponds to human miR-126. 18. The method of claim 15, wherein one of the synthetic double-stranded molecules corresponds to human miR-147. 19. A method for treating cancer in a human subject comprising administering to the subject an effective amount of one or more synthetic double-stranded miRNA molecules corresponding to human miR-16, miR-124, miR-126, miR-147, or miR-194, wherein the synthetic miRNA molecule is 17-30 nucleotides in length and comprises: a) an active strand comprising a sequence of a mature human miRNA, andb) a separate complementary strand that is fully complementary to the active strand and that comprises at least one chemical modification at the 5′ end that enhances the activity of the active strand. 20. The method of claim 19, wherein the 5′ terminus is modified with an NH2, biotin, an amine group, a lower alkylamine group, or an acetyl group. 21. The method of claim 19, wherein the synthetic double-stranded RNA molecule has a complementary strand that has a 5′ terminal nucleotide with a sugar modification. 22. The method of claim 21, wherein the sugar modification is 2′OMe. 23. The method of claim 19, wherein one of the synthetic double-stranded molecules corresponds to human miR-16. 24. The method of claim 19, wherein one of the synthetic double-stranded molecules corresponds to human miR-124. 25. The method of claim 19, wherein one of the synthetic double-stranded molecules corresponds to human miR-126. 26. The method of claim 19, wherein one of the synthetic double-stranded molecules corresponds to human miR-147. 27. The method of claim 19, wherein one of the synthetic double-stranded molecules corresponds to human miR-194.
