Cordycepin Triphosphate as a Potential Modulator of Cellular Plasticity in Cancer via cAMP-Dependent Pathways: An In Silico Approach. Int J Mol Sci 2024; 25:5692. [PMID: 38891880 PMCID: PMC11171877 DOI: 10.3390/ijms25115692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 05/14/2024] [Accepted: 05/21/2024] [Indexed: 06/21/2024] Open
Abstract
Cordycepin, or 3'-deoxyadenosine, is an adenosine analog with a broad spectrum of biological activity. The key structural difference between cordycepin and adenosine lies in the absence of a hydroxyl group at the 3' position of the ribose ring. Upon administration, cordycepin can undergo an enzymatic transformation in specific tissues, forming cordycepin triphosphate. In this study, we conducted a comprehensive analysis of the structural features of cordycepin and its derivatives, contrasting them with endogenous purine-based metabolites using chemoinformatics and bioinformatics tools in addition to molecular dynamics simulations. We tested the hypothesis that cordycepin triphosphate could bind to the active site of the adenylate cyclase enzyme. The outcomes of our molecular dynamics simulations revealed scores that are comparable to, and superior to, those of adenosine triphosphate (ATP), the endogenous ligand. This interaction could reduce the production of cyclic adenosine monophosphate (cAMP) by acting as a pseudo-ATP that lacks a hydroxyl group at the 3' position, essential to carry out nucleotide cyclization. We discuss the implications in the context of the plasticity of cancer and other cells within the tumor microenvironment, such as cancer-associated fibroblast, endothelial, and immune cells. This interaction could awaken antitumor immunity by preventing phenotypic changes in the immune cells driven by sustained cAMP signaling. The last could be an unreported molecular mechanism that helps to explain more details about cordycepin's mechanism of action.

Abstract
Tropomyosins coat actin filaments and impact actin-related signaling and cell morphogenesis. Genome-wide association studies have linked Tropomyosin 1 (TPM1) with human blood trait variation. Prior work suggested that TPM1 regulated blood cell formation in vitro, but it was unclear how or when TPM1 affected hematopoiesis. Using gene-edited induced pluripotent stem cell (iPSC) model systems, TPM1 knockout was found to augment developmental cell state transitions, as well as TNFα and GTPase signaling pathways, to promote hemogenic endothelial (HE) cell specification and hematopoietic progenitor cell (HPC) production. Single-cell analyses showed decreased TPM1 expression during human HE specification, suggesting that TPM1 regulated in vivo hematopoiesis via similar mechanisms. Indeed, analyses of a TPM1 gene trap mouse model showed that TPM1 deficiency enhanced the formation of HE during embryogenesis. These findings illuminate novel effects of TPM1 on developmental hematopoiesis.

Abstract
Hematopoietic stem cells (HSC) give rise to all types of blood lineages, including red blood cells (RBC). Hematopoietic stem/progenitor cells (HSPC) are known to be functionally diverse in terms of their self-renewal potential and lineage output. Consequently, investigation of molecular heterogeneity in the differentiation potential of HSPC is vital to identify novel regulators that affect generation of specific cell types, especially RBC. Here, we compared the erythroid potential of CD34+ hematopoietic stem and progenitor cells from 50 different umbilical cord blood (UCB) donors and discovered that those donors gave rise to diverse frequencies of Glycophorin-A+ erythroid cells after in vitro differentiation, despite having similar frequencies of phenotypic HSC initially. RNA sequencing revealed that genes involved in G protein-coupled receptor (GPCR) signaling were significantly up-regulated in the high-erythroid output donors. When we chemically modified two main signaling elements in this pathway, adenylyl cyclase (AC) and phosphodiesterase (PDE), we observed that inhibition of PDE led to 10 times higher yield of Glycophorin-A+ cells than activation of AC. Our findings suggest that GPCR signaling, and particularly the cAMP-related pathway, contributes to the diversity of erythroid potential among UCB donors.

Abstract
The splenic microenvironment regulates hematopoietic stem and progenitor cell (HSPC) function, particularly during demand-adapted hematopoiesis; however, practical strategies to enhance splenic support of transplanted HSPCs have proved elusive. We have previously demonstrated that inhibiting 15-hydroxyprostaglandin dehydrogenase (15-PGDH), using the small molecule (+)SW033291 (PGDHi), increases BM prostaglandin E2 (PGE2) levels, expands HSPC numbers, and accelerates hematologic reconstitution after BM transplantation (BMT) in mice. Here we demonstrate that the splenic microenvironment, specifically 15-PGDH high-expressing macrophages, megakaryocytes (MKs), and mast cells (MCs), regulates steady-state hematopoiesis and potentiates recovery after BMT. Notably, PGDHi-induced neutrophil, platelet, and HSPC recovery were highly attenuated in splenectomized mice. PGDHi induced nonpathologic splenic extramedullary hematopoiesis at steady state, and pretransplant PGDHi enhanced the homing of transplanted cells to the spleen. 15-PGDH enzymatic activity localized specifically to macrophages, MK lineage cells, and MCs, identifying these cell types as likely coordinating the impact of PGDHi on splenic HSPCs. These findings suggest that 15-PGDH expression marks HSC niche cell types that regulate hematopoietic regeneration. Therefore, PGDHi provides a well-tolerated strategy to therapeutically target multiple HSC niches, promote hematopoietic regeneration, and improve clinical outcomes of BMT.

Abstract
A major obstacle for using human pluripotent stem cells (hPSCs) derived vascular cells for cell therapy is the lack of simple, cost-saving, and scalable methods for cell production. Here we described a simplified and chemically defined medium (AATS) for endothelial cells (ECs) and smooth muscle cells (SMCs) differentiation. AATS medium does not contain insulin, enabling the rapid and highly efficient vascular mesoderm formation through accelerating metabolic and autophagy-enhanced mesoderm induction. Transcriptome profiling confirmed that hPSC-derived ECs and SMCs in the AATS medium closely resembled primary ECs and SMCs formed in vivo. ECs appeared to adhere and grow better in the AATS medium over other cell types, which allowed the purification of CD31+CD144+ double-positive cells. Furthermore, the AATS medium was compatible with 3D microscaffold (MS) culture, which may facilitate large-scale bioproduction of ECs. HPSC-derived ECs and SMCs in the AATS medium exhibited strong revascularization potential in treating murine ischemic models. Our study provided a cost-effective and efficient medium system to manufacture GMP compatible, off-the-shelf ECs, and SMCs to model human diseases and vascular repair.

Abstract
Embryonic definitive hematopoiesis generates hematopoietic stem and progenitor cells (HSPCs) essential for establishment and maintenance of the adult blood system. This process requires the specification of a subset of vascular endothelial cells to become blood-forming, or hemogenic, and the subsequent endothelial-to-hematopoietic transition to generate HSPCs therefrom. The mechanisms that regulate these processes are under intensive investigation, as their recapitulation in vitro from human pluripotent stem cells has the potential to generate autologous HSPCs for clinical applications. In this review, we provide an overview of hemogenic endothelial cell development and highlight the molecular events that govern hemogenic specification of vascular endothelial cells and the generation of multilineage HSPCs from hemogenic endothelium. We also discuss the impact of hemogenic endothelial cell development on adult hematopoiesis.

Abstract
Stroke breaks the oxidative balance in the body and causes extra reactive oxygen species (ROS) generation, leading to oxidative stress damage. Long noncoding RNAs (lncRNAs) and microRNAs play pivotal roles in oxidative stress-mediated brain injury. Safflor yellow B (SYB) was able to effectively reduce ischemia-mediated brain damage by increasing antioxidant capacity and inhibiting cell apoptosis. In this study, we investigated the putative involvement of lncRNA AK046177 and microRNA-134 (miR-134) regulation in SYB against ischemia/reperfusion- (I/R-) induced neuronal injury. I/R and oxygen-glucose deprivation/reoxygenation (OGD/R) were established in vivo and in vitro. Cerebral infarct volume, neuronal apoptosis, and protein expression were detected. The effects of SYB on cell activity, cell respiration, nuclear factor erythroid 2-related factor 2 (Nrf2), antioxidant enzymes, and ROS were evaluated. I/R or OGD/R upregulated the expression of AK046177 and miR-134 and subsequently inhibited the activation and expression of CREB, which caused ROS generation and brain/cell injury. SYB attenuated the effects of AK046177, inhibited miR-134 expression, and promoted CREB activation, which in turn promoted Nrf2 expression, and then increased antioxidant capacities, improved cell respiration, and reduced apoptosis. We suggested that the antioxidant effects of SYB were driven by an AK046177/miR-134/CREB-dependent mechanism that inhibited this pathway, and that SYB has potential use in reducing or possibly preventing I/R-induced neuronal injury.

Abstract
Although the generation of ETV2-induced endothelial cells (iECs) from human fibroblasts serves as a novel therapeutic strategy in regenerative medicine, the process is inefficient, resulting in incomplete iEC angiogenesis. Therefore, we employed chromatin immunoprecipitation (ChIP) sequencing and identified molecular mechanisms underlying ETV2-mediated endothelial transdifferentiation to efficiently produce iECs retaining appropriate functionality in long-term culture. We revealed that the majority of ETV2 targets in human fibroblasts are related to vasculature development and signaling transduction pathways, including Rap1 signaling. From a screening of signaling pathway modulators, we confirmed that forskolin facilitated efficient and rapid iEC reprogramming via activation of the cyclic AMP (cAMP)/exchange proteins directly activated by cAMP (EPAC)/RAP1 axis. The iECs obtained via cAMP signaling activation showed superior angiogenesis in vivo as well as in vitro. Moreover, these cells could form aligned endothelium along the vascular lumen ex vivo when seeded into decellularized liver scaffold. Overall, our study provided evidence that the cAMP/EPAC/RAP1 axis is required for the efficient generation of iECs with angiogenesis potential.

Abstract
Human pluripotent stem cells (hPSCs) generate hematopoietic progenitor cells (HPCs) but fail to engraft xenograft models used to detect adult/somatic hematopoietic stem cells (HSCs) from donors. Recent progress to derive hPSC-derived HSCs has relied on cell-autonomous forced expression of transcription factors; however, the relationship of bone marrow to transplanted cells remains unknown. Here, we quantified a failure of hPSC-HPCs to survive even 24 hr post transplantation. Across several hPSC-HPC differentiation methodologies, we identified the lack of CXCR4 expression and function. Ectopic CXCR4 conferred CXCL12 ligand-dependent signaling of hPSC-HPCs in biochemical assays and increased migration/chemotaxis, hematopoietic progenitor capacity, and survival and proliferation following in vivo transplantation. This was accompanied by a transcriptional shift of hPSC-HPCs toward somatic/adult sources, but this approach failed to produce long-term HSC xenograft reconstitution. Our results reveal that networks involving CXCR4 should be targeted to generate putative HSCs with in vivo function from hPSCs. Transplant kinetics indicate human PSC-HPCs fail in the first 24 hr in bone marrow hPSC-HPCs aberrantly express chemokine receptors, specifically lacking CXCR4 Ectopic CXCR4 enhances hPSC-HPC function in vitro and transplantation in vivo CXCR4 linked with global transcriptional shift of hPSC-HPCs toward somatic HPCs

Abstract
The formation and remodeling of a functional circulatory system is critical for sustaining prenatal and postnatal life. During embryogenesis, newly differentiated endothelial cells require further specification to create the unique features of distinct vessel subtypes needed to support tissue morphogenesis. In this review, we explore signaling pathways and transcriptional regulators that modulate endothelial cell differentiation and specification, as well as applications of these processes to stem cell biology and regenerative medicine. We also summarize recent technical advances, including the growing utilization of single-cell sequencing to study vascular heterogeneity and development.

Abstract
Recent advances in genetic engineering technology and stem cell biology have spurred great interest in developing gene therapies for hereditary, as well as acquired hematological disorders. Currently, hematopoietic stem cell transplantation is used to cure disorders such as hemoglobinopathies and primary immunodeficiencies; however, this method is limited by the availability of immune-matched donors. Using autologous cells coupled with genome editing bypasses this limitation and therefore became the focus of many research groups aiming to develop efficient and safe genomic modification. Hence, gene therapy research has witnessed a noticeable growth in recent years with numerous successful achievements; however, several challenges have to be overcome before gene therapy becomes widely available for patients. In this review, I discuss tools used in gene therapy for hematological disorders, choices of target cells, and delivery vehicles with emphasis on current hurdles and attempts to solve them, and present examples of successful clinical trials to give a glimpse of current progress.

Abstract
INTRODUCTION Stem cells from the apical papilla (SCAPs) possess strong odonto/osteogenic differentiation potential. This study investigated the effect of cyclic adenosine monophosphate (cAMP) on odonto/osteogenic differentiation of SCAPs and the underlining interplay between cAMP and transforming growth factor beta 1 (TGF-β1). METHODS SCAPs were stimulated with an activator of cAMP (forskolin) in the presence of either TGF-β1 or a TGF-β1 inhibitor. The amounts of calcium mineral deposition and alkaline phosphatase activity were determined. Quantitative real-time polymerase chain reaction was performed to elucidate cAMP on the TGF-β1-mediated odonto/osteogenic differentiation of SCAPs. The effect of cAMP on the phosphorylation of Smad2/Smad3 and extracellular-regulated kinase (ERK)/P38 induced by TGF-β1 was analyzed by Western blotting. RESULTS Cotreatment with forskolin and a TGF-β1 inhibitor enhanced alkaline phosphatase activity and deposition of calcium minerals in SCAPs. Moreover, the TGF-β1 inhibitor synergized the effect of forskolin on the expression of type I collagen and runt-related transcription factor 2. The results of Western blotting revealed that forskolin attenuated the unregulated expression of the phosphorylation of Smad3 and ERK induced by TGF-β1, and a cAMP inhibitor (H89) antagonized this effect. CONCLUSIONS This study showed that cAMP signaling exerts its up-regulating effects on the odonto/osteogenic differentiation of SCAPs by interfering with TGF-β1 signaling via inhibiting Smad3 and ERK phosphorylation.

Abstract
Epac1 (Exchange protein directly activated by cAMP 1) limits fluid loss from the circulation by tightening the endothelial barrier. We show here that Epac1-/- mice, but not Epac2-/- mice, have prolonged bleeding time, suggesting that Epac1 may limit fluid loss also by restraining bleeding. The Epac1-/- mice had deficient in vitro secondary hemostasis. Quantitative comprehensive proteomics analysis revealed that Epac1-/- mouse platelets (thrombocytes) had unbalanced expression of key components of the glycoprotein Ib-IX-V (GPIb-IX-V) complex, with decrease of GP1bβ and no change of GP1bα. This complex is critical for platelet adhesion under arterial shear conditions. Furthermore, Epac1-/- mice have reduced levels of plasma coagulation factors and fibrinogen, increased size of circulating platelets, increased megakaryocytes (the GP1bβ level was decreased also in Epac1-/- bone marrow) and higher abundance of reticulated platelets. Viscoelastic measurement of clotting function revealed Epac1-/- mice with a dysfunction in the clotting process, which corresponds to reduced plasma levels of coagulation factors like factor XIII and fibrinogen. We propose that the observed platelet phenotype is due to deficient Epac1 activity during megakaryopoiesis and thrombopoiesis, and that the defects in blood clotting for Epac1-/- is connected to secondary hemostasis.

Abstract
Here, we report the derivation of arterial endothelial cells from human pluripotent stem cells that exhibit arterial-specific functions in vitro and in vivo. We combine single-cell RNA sequencing of embryonic mouse endothelial cells with an EFNB2-tdTomato/EPHB4-EGFP dual reporter human embryonic stem cell line to identify factors that regulate arterial endothelial cell specification. The resulting xeno-free protocol produces cells with gene expression profiles, oxygen consumption rates, nitric oxide production levels, shear stress responses, and TNFα-induced leukocyte adhesion rates characteristic of arterial endothelial cells. Arterial endothelial cells were robustly generated from multiple human embryonic and induced pluripotent stem cell lines and have potential applications for both disease modeling and regenerative medicine.

Abstract
Cell stressors, such as elevated levels of reactive oxygen species (ROS), adversely affect hematopoietic stem cell (HSC) reconstituting ability. However, the effects of ROS have not been evaluated in the context of hematopoietic development from human pluripotent stem cells (hPSCs). Using our previously described in vitro system for efficient derivation of hematopoietic cells from hPSCs, we show that the vast majority of generated hematopoietic cells display supraphysiological levels of ROS compared to fresh cord blood cells. Elevated ROS resulted in DNA damage of the CD34+ hematopoietic fraction and, following functional assays, reduced colony formation and impaired proliferative capacity. Interestingly, all the proliferative potential of the most primitive hematopoietic cells was limited to a small fraction with low ROS levels. We show that elevation of ROS in hPSC-derived hematopoietic cells is contributed by multiple distinct cellular processes. Furthermore, by targeting these molecular processes with 4 unique factors, we could reduce ROS levels significantly, yielding a 22-fold increase in the most primitive CD90+ CD34+ hematopoietic cells with robust growth capacity. We demonstrate that the ROS reducing factors specifically reduced ROS in more primitive hematopoietic fractions, in contrast to endothelial cells that maintained low ROS levels in the cultures. We conclude that high levels of ROS in in vitro differentiation systems of hPSCs is a major determinant in the lack of ability to generate hematopoietic cells with similar proliferation/differentiation potential to in vivo hematopoietic progenitors, and suggest that elevated ROS is a significant barrier to generating hPSC-derived repopulating HSCs.
