Abstract:
Abstract Background: AKT1 E17K is an activating driver mutation with a prevalence of 4-8% in breast cancer, with the vast majority found in HR+/HER2-negative breast cancer. Approximately 90% of AKT driver mutations are AKT1 E17K, and half of AKT1 E17K-mutant breast and gynecologic cancers are homozygous for the AKT1 E17K oncogene with concurrent loss of the wildtype (WT) AKT1 allele. These genomic features suggest AKT1 E17K exhibits uniquely potent oncogene addiction in these tumor types. Non mutant-selective AKT inhibitors have demonstrated clinical activity in patients with AKT1 E17K-mutant

Abstract:
The AKT1 oncogene is related to various cancers due to its critical role in the PIC3CA/AKT1 pathway; however, most of the studies screened the hotspot mutation AKT1 (E17K) with various incidences. Low frequency or lack of AKT1 (E17K) mutation was reported in prostate cancer (PC) patients. This study aims to explore genetic alterations in the AKT1 PH domain by extending the sequencing to include AKT1 gene exons 3 and 4. Genomic DNA was extracted from 84 Formalin-Fixed Paraffin-Embedded samples of PC patients in Jordan, and then subjected to PCR and sequencing for the targeted exons. This study

Abstract Abstract 4262 AKT1 E17K mutation was recently found in several human cancers. PI3K/AKT is one of major downstream signal pathways of BCR-ABL oncogene and essential for CML leukemogenesis and IM resistance. More recently, it has been shown that increased PI3K/AKT activity in CML contributes to the development of drug resistance of malignant cells and combination of PI3K/AKT pathway inhibitor and rapamycin can efficiently kill imatinib-resistant BCR-ABL-expressing cells, highlighting the potential of PI3K/AKT as the new targets for CML therapy. Considering the central role of AKT in CML

Abstract:
Purpose AKT1 E17K mutations are oncogenic and occur in many cancers at a low prevalence. We performed a multihistology basket study of AZD5363, an ATP-competitive pan-AKT kinase inhibitor, to determine the preliminary activity of AKT inhibition in AKT-mutant cancers. Patients and Methods Fifty-eight patients with advanced solid tumors were treated. The primary end point was safety; secondary end points were progression-free survival (PFS) and response according to Response Evaluation Criteria in Solid Tumors (RECIST). Tumor biopsies and plasma cell-free DNA (cfDNA) were collected in the majori

Abstract INTRODUCTION Spinal meningiomas represent about one-third of all spine tumors. To date, little is known about the molecular profile of spinal meningiomas and their clinical impact. In this study, we correlate clinical parameters with targeted sequencing findings in a well-characterized cohort of 42 patients with spinal meningiomas. METHODS Samples from 42 spinal meningiomas (31 females and 11 males) were collected. Targeted sequencing for AKT1 E17K hot spot mutations was performed. Furthermore, clinical and imaging data were collected and correlated with the AKT1 mutation status. RESU

Abstract:
The prevalence of a novel somatic mutation (E17K) in the pleckstrin homology domain of AKT1 was investigated in pancreatic cancer using a quantitative pyrosequencing assay. This mutation was un-detectable in pancreatic cancer tissue samples (n=65) and pancreatic cell line (n=10) DNA suggesting that pancreatic cancer progression is mainly dependent on the K-Ras mutation.

Abstract INTRODUCTION While the mutational landscape of intracranial meningiomas has been extensively studied, our understanding of the molecular profile of spinal meningiomas (SM) remains incomplete. In this study, we correlate the molecular status with tumor features in a clinically well-characterized cohort. METHODS Samples from 50 patients (38 females and 12 males) with WHO grade 1 SM were collected. We performed next-generation sequencing (NGS) using an assay covering frequently mutated genes in meningiomas including AKT1, KLF4, NF2, PIK3CA, POLR2A, SMARCB1, SMARCE1, SMO, SUFU, and TRAF7.
