MAPK/ERK and PI3K/AKT signaling pathways are activated in adolescent and adult acute lymphoblastic leukemia

Background: The mitogen‐activated protein kinase (MAPK)/ERK signaling cascade and the phosphoinosytol‐3 phosphate/Akt (PI3K/Akt) pathways are involved in proliferation and differentiation of hematopoietic cells. The frequency of PI3K/Akt and MAPK pathway activation in adult acute lymphoblastic leuke...

description Background: The mitogen‐activated protein kinase (MAPK)/ERK signaling cascade and the phosphoinosytol‐3 phosphate/Akt (PI3K/Akt) pathways are involved in proliferation and differentiation of hematopoietic cells. The frequency of PI3K/Akt and MAPK pathway activation in adult acute lymphoblastic leukemia (ALL) still need to be elucidated. Aims: To assess the activity and prognostic implications of MAPK/ERK and PI3K/Akt pathways in adult (ALL). Methods We examined 28 precursor‐B‐cell ALL and 6 T‐cell primary ALL samples. Flow cytometry was employed to analyze the expression levels of phosphorylated ERK and phosphorylated Akt. Results Ten out of 15 (67%) ALL fresh samples (7 B‐cell, 3 T‐cell) showed constitutive p‐ERK expression. The p‐ERK mean fluorescent index ratio (MFI (R)) showed a tendency to be higher in ALL than in normal T lymphocytes (1.26 [0.74–3.10] vs. 1.08 [1.02–1.21], respectively [p = .069]) and was significantly lower than in leukemic cell lines (median MFI (R) 3.83 [3.71–5.97] [p

The median MFI (R) expression for p‐Akt in primary blast cell was 1.13 (0.48–9.90) compared to 1.01 (1.00–1.20) in normal T lymphocytes (p = ns) and lower than in leukemic cell lines (median MFI (R) 2.10 [1.77–3.40] [p = .037]). Moreover, expression of p‐ERK was negatively associated with the expression of CD34 (1.22 [0.74–1.33] vs. 1.52 [1.15–3.10] for CD34(+) and CD34(−) group, respectively, p = .009). Conclusion Our findings suggest that both MAPK/ERK and PI3K/Akt are constitutively activated in adult ALL, indicating a targeted therapy potential for ALL by using inhibitors of these pathways.</description><identifier>ISSN: 2573-8348</identifier><identifier>EISSN: 2573-8348</identifier><identifier>DOI: 10.1002/cnr2.1912</identifier><identifier>PMID: 37867416</identifier><language>eng</language><publisher>United States: John Wiley &amp; Sons, Inc</publisher><subject>Adolescent ; ALL ; Apoptosis ; Bone marrow ; Cell growth ; ERK ; Flow cytometry ; Glycoproteins ; Humans ; Investigations ; Kinases ; Leukemia ; MAPK ; Medical prognosis ; Mitogen-Activated Protein Kinases - metabolism ; Original ; Phosphatidylinositol 3-Kinases - metabolism ; Phosphorylation ; PI3K/Akt ; Precursor Cell Lymphoblastic Leukemia-Lymphoma ; Proteins ; Proto-Oncogene Proteins c-akt - metabolism ; Signal Transduction - physiology</subject><ispartof>Cancer reports, 2023-12, Vol.6 (12), p.e1912-n/a</ispartof><rights>2023 The Authors. published by Wiley Periodicals LLC.</rights><rights>2023 The Authors.
