Can polarization of macrophage metabolism enhance cardiac regeneration?

J Mol Cell Cardiol 2021 Jul 20;160:87-96. Epub 2021 Jul 20.

Department of Pathology, Northwestern University Feinberg School of Medicine, Chicago, IL, USA; Pediatrics, Northwestern University Feinberg School of Medicine, Chicago, IL, USA; The Heart Center, Stanley Manne Children's Research Institute, Chicago, IL, USA. Electronic address:

While largely appreciated for their antimicrobial and repair functions, macrophages have emerged as indispensable for the development, homeostasis, and regeneration of tissue, including regeneration of the neonatal heart. Upon activation, mammalian neonatal macrophages express and secrete factors that coordinate angiogenesis, resolution of inflammation, and ultimately cardiomyocyte proliferation. This is contrary to adult macrophages in the adult heart, which are incapable of inducing significant levels of cardiac regeneration. Read More

The human amniotic fluid stem cell secretome triggers intracellular Ca oscillations, NF-κB nuclear translocation and tube formation in human endothelial colony-forming cells.

J Cell Mol Med 2021 Jul 20. Epub 2021 Jul 20.

Department of Biology and Biotechnology "Lazzaro Spallanzani", Laboratory of General Physiology, University of Pavia, Pavia, Italy.

Second trimester foetal human amniotic fluid-derived stem cells (hAFS) have been shown to possess remarkable cardioprotective paracrine potential in different preclinical models of myocardial injury and drug-induced cardiotoxicity. The hAFS secretome, namely the total soluble factors released by cells in their conditioned medium (hAFS-CM), can also strongly sustain in vivo angiogenesis in a murine model of acute myocardial infarction (MI) and stimulates human endothelial colony-forming cells (ECFCs), the only truly recognized endothelial progenitor, to form capillary-like structures in vitro. Preliminary work demonstrated that the hypoxic hAFS secretome (hAFS-CM ) triggers intracellular Ca oscillations in human ECFCs, but the underlying mechanisms and the downstream Ca -dependent effectors remain elusive.

Eribulin induces tumor vascular remodeling through intussusceptive angiogenesis in a sarcoma xenograft model.

Biochem Biophys Res Commun 2021 Jul 15;570:89-95. Epub 2021 Jul 15.

Department of Orthopedic Surgery, National Defense Medical College, Namiki 3-2, Tokorozawa, Saitama, 359-8513, Japan.

Eribulin is a novel microtubule inhibitor that, similar to other types of microtubule inhibitors, induces apoptosis by inhibiting the mitotic division of cells. Besides this direct effect on tumor cells, previous studies have shown that eribulin has the potential to induce tumor vascular remodeling in several different cancers; however, the mechanisms underlying this phenomenon remain unclear. In the present study, we aimed to elucidate whether eribulin is effective against synovial sarcoma, a relatively rare sarcoma that often affects adolescents and young adults, and to histologically investigate the microstructure of tumor vessels after the administration of eribulin.

Institute for Biomedical Engineering and Institute of Pharmacology and Toxicology Faculty of Medicine University of Zurich Zurich 8057 Switzerland.

Wound healing is a well-coordinated process, necessitating efficient formation of new blood vessels. Vascularization defects are therefore a major risk factor for chronic, non-healing wounds. The dynamics of mammalian tissue revascularization, vessel maturation, and remodeling remain poorly understood due to lack of suitable in vivo imaging tools. Read More

BMP9 and BMP10: two close vascular quiescence partners that stand out.

Dev Dyn 2021 Jul 9. Epub 2021 Jul 9.

Laboratory BioSanté, Univ. Grenoble Alpes, INSERM, CEA, Grenoble, France.

Bone morphogenetic proteins (BMPs) are dimeric transforming growth factor ß (TGFß) family cytokines that were first described in bone and cartilage formation but have since been shown to be involved in many pleiotropic functions. In human, there are 15 BMP ligands, which initiate their cellular signaling by forming a complex with two copies of type I receptors and two copies of type II receptors, both of which are transmembrane receptors with an intracellular serine/threonine kinase domain. Within this receptor family, ALK1 (Activin receptor-Like Kinase 1), which is a type I receptor mainly expressed on endothelial cells, and BMPRII (BMP Receptor type II), a type II receptor also highly expressed on endothelial cells, have been directly linked to two rare vascular diseases: hereditary haemorrhagic telangiectasia (HHT), and pulmonary arterial hypertension (PAH), respectively.

Perinatal Nutritional and Metabolic Pathways: Early Origins of Chronic Lung Diseases.

Front Med (Lausanne) 2021 15;8:667315. Epub 2021 Jun 15.

Department of Pediatric and Adolescent Medicine, Translational Experimental Pediatrics-Experimental Pulmonology, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany.

Lung development is not completed at birth, but expands beyond infancy, rendering the lung highly susceptible to injury. Exposure to various influences during a critical window of organ growth can interfere with the finely-tuned process of development and induce pathological processes with aberrant alveolarization and long-term structural and functional sequelae. This concept of developmental origins of chronic disease has been coined as perinatal programming. Read More

Second-line treatment in renal cell carcinoma: clinical experience and decision making.

Ther Adv Urol 2021 Jan-Dec;13:17562872211022870. Epub 2021 Jun 18.

Istituto Nazionale dei Tumori IRCCS Milano, Milano, Lombardia, Italy.

Currently, conventional treatments for metastatic RCC (mRCC) include immune-based combination regimens and/or targeted therapies, the latter mainly acting on angiogenesis, a key element of the process of tumor growth and spread. Although these agents proved able to improve patients' outcomes, drug resistance and disease progression are still experienced by a substantial number of VEGFR-TKIs-treated mRCC patients. Following the inhibition of the VEGF/VEGFRs axis, two strategies have emerged: either specifically targeting resistance pathways, at the same time continuing to inhibit angiogenesis, or using a completely different approach aimed at re-activating the immune system through the use of inhibitors of specific negative immune checkpoints.

Biological Effects of XyloCore, a Glucose Sparing PD Solution, on Mesothelial Cells: Focus on Mesothelial-Mesenchymal Transition, Inflammation and Angiogenesis.

Nutrients 2021 Jun 30;13(7). Epub 2021 Jun 30.

Division of Nephrology and Dialysis, Department of Medicine, Piazzale A. Stefani 1, 37126 Verona, Italy.

Glucose-based solutions remain the most used osmotic agents in peritoneal dialysis (PD), but unavoidably they contribute to the loss of peritoneal filtration capacity. Here, we evaluated at a molecular level the effects of XyloCore, a new PD solution with a low glucose content, in mesothelial and endothelial cells. Cell viability, integrity of mesothelial and endothelial cell membrane, activation of mesothelial and endothelial to mesenchymal transition programs, inflammation, and angiogenesis were evaluated by several techniques.

Despite multimodal treatment strategies, clinical outcomes of advanced stage colorectal cancer (CRC) patients remain poor. Neoadjuvant/adjuvant chemotherapy efficacy is limited due to chemoresistance, toxicity, and negative side effects. Since both melatonin and glycine have anti-cancer activities without relevant side effects, this study was designed to investigate their combined effects in experimental CRC liver metastases.

The ovarian follicle is the basic functional unit of the ovary, comprising theca cells and granulosa cells (GCs). Two different types of GCs, mural GCs and cumulus cells (CCs), serve different functions during folliculogenesis. Mural GCs produce oestrogen during the follicular phase and progesterone after ovulation, while CCs surround the oocyte tightly and form the cumulus oophurus and corona radiata inner cell layer.

Decreased Cyclic GMP-protein Kinase G signaling impairs Angiogenesis in a Lamb Model of Persistent Pulmonary Hypertension of Newborn.

Am J Respir Cell Mol Biol 2021 Jun 29. Epub 2021 Jun 29.

Medical College of Wisconsin, 5506, Pediatrics, Milwaukee, Wisconsin, United States;

Impaired angiogenesis function of pulmonary artery endothelial cells (PAEC) contributes to persistent pulmonary hypertension of the newborn (PPHN). Decreased nitric oxide (NO) levels in PPHN lead to impaired mitochondrial biogenesis and angiogenesis in the lung; the mechanisms remain unclear. We hypothesized that decreased cGMP-Protein kinase G (PKG) signaling downstream of NO leads to decreased mitochondrial biogenesis and angiogenesis in PPHN. Read More
