Gene expression signature predicts relapse in adult patients with cytogenetically normal acute myeloid leukemia. Blood Adv 2021; 5:1474-1482. [PMID: 33683341 DOI: 10.1182/bloodadvances.2020003727] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 12/30/2020] [Indexed: 12/19/2022] Open
Abstract
Although ∼80% of adult patients with cytogenetically normal acute myeloid leukemia (CN-AML) achieve a complete remission (CR), more than half of them relapse. Better identification of patients who are likely to relapse can help to inform clinical decisions. We performed RNA sequencing on pretreatment samples from 268 adults with de novo CN-AML who were younger than 60 years of age and achieved a CR after induction treatment with standard "7+3" chemotherapy. After filtering for genes whose expressions were associated with gene mutations known to impact outcome (ie, CEBPA, NPM1, and FLT3-internal tandem duplication [FLT3-ITD]), we identified a 10-gene signature that was strongly predictive of patient relapse (area under the receiver operating characteristics curve [AUC], 0.81). The signature consisted of 7 coding genes (GAS6, PSD3, PLCB4, DEXI, JMY, NRP1, C10orf55) and 3 long noncoding RNAs. In multivariable analysis, the 10-gene signature was strongly associated with relapse (P < .001), after adjustment for the FLT3-ITD, CEBPA, and NPM1 mutational status. Validation of the expression signature in an independent patient set from The Cancer Genome Atlas showed the signature's strong predictive value, with AUC = 0.78. Implementation of the 10-gene signature into clinical prognostic stratification could be useful for identifying patients who are likely to relapse.

Abstract
Objective of this work is to investigate, for the first time, serum concentration of neuropilin-1 (NRP-1), aiming to evaluate its diagnostic performance in endometriosis and usability as a potential non-invasive serum marker of endometriosis. Two hundred women were treated laparoscopically. After laparoscopic surgery women were divided into two groups: 120 women diagnosed with endometriosis and 80 healthy women (control group). Blood samples were taken from all women undergoing laparoscopy half an hour before the induction of anesthesia, for the purpose of collection of serum. The level of NRP-1 in serum was assayed by a standardised sandwich enzyme-linked immunosorbent assay. Differences between endometriosis and healthy control group in NRP-1 levels were significant. All values were significantly and several times higher in patients group, p < .001. After receiver operating characteristic analysis, the area under curve was 0.97 (95% confidence interval: 0.941 to 0.989, p < .0001) at 11 µg/L cut-off level for NRP-1. Preliminary threshold values for NRP-1 in serum were assumed to serve as diagnostic parameters with sensitivity of 99.3% and specificity of 97.8%. Serum concentration of NRP-1 can be considered as a potentially good laboratory diagnostic, non-invasive marker for endometriosis.

Abstract
While semaphorins were initially identified as axonal guidance cues for wiring the neural network, it was then recognized their wide relevance in tissue development and homeostasis. Notably, semaphorin activities were also extensively studied in many types of solid tumors; however, their relevance in hematological malignancies is far from understood. In this mini-review, we surveyed the current knowledge about semaphorins and their receptors in leukemias, lymphomas, and multiple myeloma. Noteworthy, current data support a promoting role for Semaphorin 4D and Neuropilin-1 in these tumors, while Semaphorin 3A seems to consistently act as oncosuppressor in leukemias and multiple myeloma. The expression levels and functional activities of SEMA3B, SEMA3F, and Neuropilin-2 have furthermore been investigated in leukemias and lymphoma cells. Herein, we reviewed the state of the art and highlighted some of the open questions to be addressed in the field.

Role of new Immunophenotypic Markers on Prognostic and Overall Survival of Acute Myeloid Leukemia: a Systematic Review and Meta-Analysis. Sci Rep 2017; 7:4138. [PMID: 28646224 PMCID: PMC5482890 DOI: 10.1038/s41598-017-00816-2] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Accepted: 02/15/2017] [Indexed: 12/30/2022] Open
Abstract
Despite technological advances, the prognosis and survival of acute myeloid leukemia (AML) adult patients remain low, compared with other hematologic malignancies. Some antigens detected by immunophenotyping may soon play a significant role in the pathophysiologic, prognostic, and overall survival (OS) rate of AML patients. Therefore, we conducted a systematic review and meta-analysis of PubMed, Scopus, Science Direct, Web of Science, and the Cochrane Library (using PRISMA guidelines). We analyzed 11 studies and 13 antigens, detected through the immunophenotyping of 639 patients. From them, twelve exhibited a negative impact with AML prognosis. The meta-analysis demonstrated a high expression of AML markers, which have been associated with a decrease in survival over 10 months (RR 2.55; IC 95%; 1.49-4.37) and over 20 months (RR 2.46; IC 95%; 1.75-3.45). Knowing that the expression of immunophenotypic markers, which are not used on a routine basis, might be able to influence disease behavior, looks promising. However, they have been associated with a poor prognosis as well as a decrease in survival. This may allow for different chemotherapeutical protocols, including future studies for new therapeutic targets.

Interdiscip Sci 2015; 9:184-191. [PMID: 26706905 DOI: 10.1007/s12539-015-0137-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2015] [Revised: 12/05/2015] [Accepted: 12/16/2015] [Indexed: 12/01/2022]
Abstract
Neuropilin-1 (NRP-1) is a transmembrane glycoprotein receptor whose distinct sites bind semaphorins and vascular endothelial growth factor family members to mediate the role of these ligands in neuronal axon guidance and angiogenesis, respectively. Similarly, Eph receptors and ephrin ligands play critical roles in various biological functions, and deregulated activation of Eph/ephrin signaling in humans is thought to lead to tumorigenesis. Therefore, in this paper, an attempt was made to elucidate the inhibition potential of nine bioactive compounds from four different native spices of Bangladesh against this couple of receptors via molecular docking study. The molecular docking study was carried out using Vina docking protocol. Finally, the receptor-ligand interaction analysis was carried out using the Discovery Studio Client package. Quercetin and diosgenin of onion showed favorable binding with NRP-1 with low binding energy of -7.8 and -7.2 kcal/mol, respectively, in comparison with the control inhibitor (-6.1 kcal/mol). The study suggests that ligand interaction with the residues Asp 48, Thr 44, Thr 77, Tyr 81, Trp29, Ile 143 of NRP-1 and Lys 653, Phe 765, Ser 763, Thr 699, Ile 683 of Eph might be critical for the inhibitory activity of these receptors. The study provides evidence for consideration of quercetin and diosgenin of onion as valuable small ligand molecules for targeting NRP-1 receptor in treatment and prevention of neurological disorders as well as cancer.

Abstract
Objective. To investigate soluble neuropilin-1 (sNRP-1) in circulating and NRP-1 protein in cervical tissues from patients with cervical cancer or cervical intraepithelial neoplasia (CIN). Methods. sNRP-1 was measured in 64 preoperative patients and 20 controls. NRP-1 protein in cervical tissue was detected in 56 patients and 20 controls. Results. Both sNRP-1 and NRP-1 proteins were correlated with stage. sNRP-1 presented a high diagnostic ability of cervical cancer and CIN, with a sensitivity of 70.97% and a specificity of 73.68%. Conclusions. sNRP-1 in circulating can serve as a possible valuable diagnostic biomarker for cervical cancer and CIN.
