1. A synthetic, modified single-stranded oligonucleotide of 20 to 21 nucleotides in length comprising at least one modification wherein the at least one modification is selected from:
- at least one modified sugar moiety;
at least one modified internucleotide linkage;
at least one modified nucleotide, and combinations thereof;
wherein said oligonucleotide is an antisense compound which is 100% complementary to and specifically hybridizes to a natural antisense polynucleotide of a Sex Hormone Binding Globulin (SHBG) gene selected from SEQ ID NO;
2 or to a target region from nucleotides 1 to 831 of SEQ ID NO;
3 and upregulates the function and/or expression of a Sex Hormone Binding Globulin (SHBG) gene in vivo or in vitro as compared to a normal control.

Abstract
The present invention relates to antisense oligonucleotides that modulate the expression of and/or function of Sex Hormone Binding Globulia (SHBG), in particular, by targeting natural antisense polynucleotides of Sex Hormone Binding Globulin (SHBG). The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of SHBG.
