Vasoactive Peptides: Role in COVID-19 Pathogenesis and Potential Use as Biomarkers and Therapeutic Targets.

ABSTRACT:

Background

The ongoing outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as the latest threat to global health, causes overwhelming effects for the public healthcare systems worldwide. Of note, in addition to the respiratory complications, some patients with coronavirus disease 2019 (COVID-19) also develop serious cardiovascular injuries. Vasoactive peptides play an important role in a wide range of physiological and pathological conditions.

Aim

With the urgent need for exploring the specific therapeutic targets and biomarkers for the emerging COVID-19, the general aim of this review is to discuss the potentials of the vasoactive peptides including Angiotensin II (Ang II), vasoactive intestinal peptide (VIP), endothelin-1 (ET-1), calcitonin gene-related peptide (CGRP), natriuretic peptides, substance P (SP) and bradykinin (BK) as therapeutic targets and/or prognostic indicators for the COVID-19 pandemic.

Conclusion

Based on various observations some authors conclude that the assessment of vasoactive peptides shall be considered a routine part of COVID-19 patient monitoring, and they can serve as potential therapeutic targets for the disease management.

Project description:Rhabdoid tumors (RT) are aggressive tumors characterized by genetic loss of SMARCB1 (SNF5, INI-1), a component of the SWI/SNF chromatin remodeling complex. No effective treatment is currently available. This study seeks to shed light on the SMARCB1-mediated pathogenesis of RT and to discover potential therapeutic targets. Global gene expression of 10 RT was compared with 12 cellular mesoblastic nephromas, 16 clear cell sarcomas of the kidney, and 15 Wilms tumors. 114 top genes were differentially expressed in RT (p<0.001, fold change >2 or <0.5). Among these were down-regulation of SMARCB1 and genes previously associated with SMARCB1 (ATP1B1, PTN, DOCK4, NQO1, PLOD1, PTP4A2, PTPRK). 28/114 top differentially expressed genes were involved with neural or neural crest development and were all sharply down-regulated. This was confirmed by Gene Set Enrichment Analysis (GSEA). Neural and neural crest stem cell marker proteins SOX10, ID3, CD133 and Musashi were negative by immunohistochemistry, whereas Nestin was positive. Decreased expression of CDKN1A, CDKN1B, CDKN1C, CDKN2A, and CCND1 was identified, while MYC-C was upregulated. GSEA of independent gene sets associated with bivalent histone modification and polycomb group targets in embryonic stem cells demonstrated significant negative enrichment in RT. Several differentially expressed genes were associated with tumor suppression, invasion and metastasis, including SPP1 (osteopontin), COL18A1 (endostatin), PTPRK, and DOCK4. We conclude that RTs arise within early progenitor cells during a critical developmental window in which loss of SMARCB1 directly results in repression of neural development, loss of cyclin dependent kinase inhibition, and trithorax/polycomb dysregulation. Keywords: Gene expression; rhabdoid tumor; pediatric renal tumors; neural crest The goal of this study is to identify genetic pathways that will clarify the nature of RT and enable the identification of therapeutic targets. Experimental Design: Frozen tissue samples were obtained from the Renal Tumor Bank of the Children's Oncology Group (COG). A total of 53 tumors were hybridized to Affymetrix U133A arrays and analyzed including 10 RT, 12 cellular mesoblastic nephromas (CMN), also known as infantile fibrosarcomas, 16 clear cell sarcomas of the kidney (CCSK) and 15 Wilms tumors (WT). Quality control steps taken: 1. Samples were snap frozen immediately following surgery and were mailed on dry ice to the Tumor Bank and retained at -80Â°C. 2. Frozen sections were evaluated histologically and tumors with less than 80% viable tumor cellularity were excluded. 3. Array images were assessed by eye to confirm scanner alignment and the absence of significant bubbles or scratches. 4. Samples for which the 3'/5' ratios for GAPDH were greater than 3.4 were excluded. 5. The BioB spike controls were confirmed as present 90% of the time; BioC, BioD and cre were confirmed as increasing intensity in all samples. 6. When scaled to a target intensity of 2500, scaling factors were between 13 and 52; background levels were 34-115: Raw Q values were 1.3-3.7 and mean intensities were within acceptable limits. 7. The range of percent present calls was from 30% to 52%. Statistical Analysis: Positional-dependent-nearest-neighbor model (PDNN) software was used to translate the scanned images into expression analysis files and to normalize the data across all arrays (http://odin.mdacc.tmc.edu/~zhangli/PerfectMatch/). To establish a broad list of probesets containing the majority of genes significant in the pathogenesis of RT, the expression of 10 RT was compared with the 43 other tumor types combined (non-RT) using the two-sample t-test, resulting in 2921 probesets with p-value <0.005 and false discovery rate of <1%. This data is provided in the attached supplementary file 'Supplemental Table 1'. To define probesets more uniquely expressed in RT, the gene expression of RT was compared with each of the other tumor types separately (CCSK, CMN, and WT) using the two-sample t-test, and genes present in each one of the resulting four comparisons (RT vs. CCSK, RT vs. CMN, RT vs. WT and RT vs non-RT) with a p-value of <0.001 are provided in the attached supplementary file 'Supplemental Table 2'. Lastly, the 766 genes differentially expressed between RT and non-RT (p<0.0001) were analyzed in PANTHER (Protein ANalysis THrough Evolutionary Relationships), and those groups within the biologic process category over-represented with a Bonferoni corrected p value<0.05 are listed in the attached file labelled âSupplemental Table 3â.
