Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Main Article Content
The utility of Insulin Like Growth Factor Binding Proteins (IGFBPs-1, 2, 3) with genes expression in resistance to Imatinib and Nilotinib in chronic myeloid leukemia: a pilot study from Delta Egypt
Abstract
Introduction: Resistance to tyrosine kinase inhibitors (TKIs) is an obstacle facing CML patients in spite of the high cure rate. In this context, a study association between IGFBP (1, 2, 3) genes expression and their proteins in CML with the response to TKI has been implicated.
Patients and methods: 115 newly diagnosed CML in chronic phase (CP) followed up over 12 months under TKI. 116 apparently healthy individuals were used as a control. RT-qPCR amplification was used for detecting IGFBPs genes expression, and ELISA technique was used for measuring serum IGFBPs.
Results: IGFBP-1 and IGFBP-3 genes expression, as well as their serum levels, were significantly higher in CML patients, whereas IGFBP-2 gene expression was not. Interestingly, IGFBP-1 gene expression and IGFBP-1 serum levels were significantly higher in resistant patients compared to responder patients. However, the expression of IGFBP-2, 3 genes and their serum were insignificant.
Conclusion: IGFBP-1 gene expression and its serum were significantly correlated with resistance. It is currently recommended that IGF-receptor inhibitors be developed and utilized. We are hoping to optimize the cure rate for CML treated with TKIs.
