Erg Chebbi Erg Chebbi Erg Chebbi () is one of Morocco's several ergs – large seas of dunes formed by wind-blown sand. There are several other ergs such as Erg Chigaga near M'hamid. Technically all these ergs are within an area of semi-arid Pre-Saharan Steppes and not part of the Sahara desert which lies some distance to the south. In places, the dunes of Erg Chebbi rise up to 150 meters from the surrounding hamada (rocky desert) and altogether it spans an area of 28 kilometers from north to south and up to 5–7 kilometers from east to west lining the Algerian
ERG (gene) applications in using blood stem cells for tissue repair, transplantation and other therapeutic applications. This gene can be classified as a proto-oncogene. During chromosomal translocations that occur in cell division, "ERG" can accidentally get stuck onto a different chromosome than where it belongs. This is analogous to another translocation, the Philadelphia chromosome. This results in fusion gene products, which can have bad consequences for cells. Examples of these fusion gene products would be TMPRSS2-ERG and NDRG1-ERG in prostate cancer, EWS-ERG in Ewing’s sarcoma, and FUS-ERG in acute myeloid leukemia. DNA binding protein ERG fuses with RNA binding proteins EWS and
