From 2008 through 2016, the number of uninsured children in the United States decreased from 7.6 million to 3.6 million (Alker & Roygardner, 2019). However, since 2017 that trend has reversed. Over 4 million children are now uninsured—the highest rate of uninsured children since the implementation of the Affordable Care Act (ACA)—and over one-quarter of these children are aged under 6 years (Burak, Clark, & Roygardner, 2019). According to the periodicity schedule for preventive pediatric...
So, how do I start this? As I'm writing this, it is the 3rd week in March, and I'm grappling with how the COVID-19 pandemic has changed life as we knew it. Like many of you at this point, I'm struggling with how to be fully informed but not be overwhelmed with information that's not always accurate. We've rescheduled many patients in our pediatric primary care site, so while at home I'm doing online training in telehealth and will be helping to staff our clinic's call center. Being geographically...

Abstract Dermatofibrosarcoma protuberans (DFSP) is the most common dermal sarcoma; it is characterized by the presence of the COL1A1–PDGFB translocation, which causes the constitutive activation of the platelet-derived growth factor β (PDGFB) signaling pathway. DFSP frequently exhibits local recurrence and is refractory to conventional chemotherapy. Therefore, a novel therapeutic strategy is required for improving the prognosis of DFSP. Although patient-derived cell lines are important...
Abstract The tumor microenvironment (TM) is an essential factor of tumor progression. Mesenchymal stem cells (MSCs) are important components of the TM and play critical roles in cancer metastasis. Resveratrol (RES) is a potential antitumor drug that has attracted extensive attention. However, it remains unclear whether RES can exert its antitumor activity by targeting MSCs located in the TM. In this study, we demonstrated that the conditioned medium of gastric-cancer-derived MSCs...
Abstract Chronic myeloid leukemia (CML) is a hematopoietic stem cell disease caused by abnormal DNA replication of bone marrow stem cells and chemotherapy resistance is a major obstacle to the effective treatment of patients with CML. Imatinib (IM), a tyrosine kinase inhibitor (TKI), is a first-line drug clinically used for CML. Mounting evidence has indicated that the dysregulation of microRNAs (miRNAs) is associated with the chemoresistance of CML. In this study, miR-153-3p,...
Abstract This study is to analyze the potential contribution of Syndecan 1 (SDC1) to cisplatin resistance in hepatic carcinoma. Cell proliferation and viability were determined by direct counting and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, respectively. The protein levels of SDC1, p-AKT, AKT and β-actin were quantified by western blotting. The SDC1 transcript abundance was measured by real-time polymerase chain reaction. The relative expression of SDC1...
Abstract Studies of human genetic disorders and animal models indicate that matriptase plays essential roles in proteolytic processes associated with profilaggrin processing and desquamation at late stages of epidermal differentiation. The tissue distribution profile and zymogen activation status in human skin, however, suggests that matriptase physiological function in the skin more likely lies in the proliferating and differentiating keratinocytes in the basal and spinous layers....
Abstract Anterior gradient 2 (AGR2) was proved to modulate cancer progression. However, the role of AGR2 on endometrial cancer was not established. Here, we investigated the effects of AGR2 expression on endometrial cancer and explored the regulation mechanism. In the study, we found that AGR2 was overexpressed in tumor tissues of 30 endometrial cancer patients. A high level of AGR2 promoted endometrial cancer cells proliferation, migration and invasion. AGR2 induced the expression...
Abstract Spindle-cell/sclerosing rhabdomyosarcoma (ssRMS) is a rare subtype of rhabdomyosarcoma, characterized by unique pathological features. Although distinctive molecular backgrounds such as frequent mutations in MyoD1 have been reported, optimized therapy has not been fully developed, and further investigations are required. Patient-derived cancer models are critical tools for basic and pre-clinical studies. However, there is no model for ssRMS. Thus, this study aimed to develop...
Abstract Melanoma is a common skin cancer and it can lead to high mortality probably by early invasion and metastasis. LncRNA MIAT is involved in tumor proliferation, invasion and epithelial-to-mesenchymal transition (EMT). However, the roles of MIAT in melanoma still require further investigation. Thus, the aim of the study is to investigate the roles of MIAT in melanoma, especially the effects of MIAT on EMT of melanoma cancer cells. The results showed that the expression of...
Abstract Bone marrow mesenchymal stromal cells (BM-MSCs) from healthy donors are a promising source of cell therapy. However, their effectiveness in cancer remains less known. This study is the first to evaluate the quality of BM-MSCs obtained from young and elderly healthy volunteers (KNT cells). The KNT cells had normal karyotypes and were positive for MSC markers (CD90, CD73, CD105). When cultured under appropriate conditions, they showed adipogenic or osteogenic potential....

Abstract Purpose Fibrocalcific aortic valve disease (CAVD) is caused by the deposition of calcific nodules in the aortic valve leaflets, resulting in progressive loss of function that ultimately requires surgical intervention. This process is actively mediated by the resident valvular interstitial cells (VICs), which, in response to oxidized lipids, transition from a quiescent to an osteoblast-like state. The purpose of this study was...
Abstract Purpose Optimal assessment of cardiovascular performance requires simultaneous measurement of load independent left ventricular (LV) contractility, arterial function and LV/arterial coupling. We aimed to demonstrate feasibility of non-invasive ventricular pressure–volume and aortic pressure-flow-impedance measurements using simultaneous arterial tonometry (AT) and cardiovascular magnetic resonance imaging (CMRI). ...
Abstract Purpose Modeling of hemolysis due to fluid stresses faces significant methodological challenges, particularly in geometries with turbulence or complex flow patterns.

Summary One of the key features of acute myeloid leukemia (AML) is the arrest of differentiation at the early progenitor stage of myelopoiesis. Therefore, the identification of new agents that could overcome this differentiation block and force leukemic cells to enter the apoptotic pathway is essential for the development of new treatment strategies in AML. Regarding this, herein we report the pro-differentiation activity of the pan-Bcl-2 inhibitor, obatoclax. Obatoclax promoted...
Summary Purpose Apatinib, a new tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, has shown promising efficacy against several solid cancers, but evidence of its efficacy against relapsed and refractory nasopharyngeal carcinoma is limited. We investigated the efficacy and safety of apatinib for relapsed and refractory nasopharyngeal carcinoma in an open-label, single-arm, phase II clinical trial. Fifty-one patients with relapsed and refractory nasopharyngeal...
Summary A new drug, Caba-780, was synthesized by chemical coupling of the heptamethyl phthalocyanine near-infrared fluorescent (NIRF) dye IR-780 and the paclitaxel-based chemotherapeutic drug cabazitaxel. Then, the potential value of Caba-780 in the diagnosis and treatment of castration-resistant prostate cancer (CRPC) was evaluated. The CRPC cell lines DU145 and PC-3, as well as the normal human prostate stromal cell line WPMY-1, were used to evaluate the uptake of Caba-780 and...
Summary Tivantinib has been described as a selective inhibitor of c-Met and is being studied in various types of cancer. In this study, we evaluated the effects of tivantinib on the suppression of gastric cancer (GC) cell migration and apoptosis. We also examined the mechanism of action of tivantinib by oncogenic pathway analysis. We applied an RNA-sequencing approach in 34 GC patients to identify oncogenes that are differentially expressed in GC tissues. To examine the inhibitory...
Summary Purpose Combining small-molecule inhibitors of different targets was shown to be synergistic in preclinical studies. Testing this concept in clinical trials is, however, daunting due to challenges in toxicity management and efficacy assessment. This study attempted to evaluate the safety and efficacy of vatalanib plus everolimus in patients with advanced solid tumors and explore the utility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies as a predictive...
Summary Introduction Triple negative breast cancer (TNBC) represents a heterogeneous subtype of breast cancer that carries a poorer prognosis. There remains a need to identify novel drivers of TNBC, which may represent targets to treat the disease. c-Met overexpression is linked with decreased survival and is associated with the basal subtype of breast cancer. Cpd A, a kinase inhibitor selective/specific for Met kinase has demonstrated preclinical anti-cancer efficacy in TNBC....
Summary Introduction Oral formulations of docetaxel have successfully been developed as an alternative for intravenous administration. Co-administration with the enzyme inhibitor ritonavir boosts the docetaxel plasma exposure. In dose-escalation trials, the maximum tolerated doses for two different dosing regimens were established and dose-limiting toxicities (DLTs) were recorded. The aim of current analysis was to develop a pharmacokinetic...
Summary One of the strategies employed by novel anticancer therapies is to put the process of apoptosis back on track by blocking the interaction between inhibitor of apoptosis proteins (IAPs) and caspases. The activity of caspases is modulated by the caspases themselves in a caspase/procaspase proteolytic cascade and by their interaction with IAPs. Caspases can be released from the inhibitory influence of IAPs by proapoptotic proteins such as secondary mitochondrial activator...
Summary Neuroendocrine tumors (NETs) are understudied and have limited systemic treatment options. Prior studies for patients with advanced NETs have demonstrated promising results when antimetabolite agents, including fluoropyrimidines, were combined with temozolomide TMZ. TAS-102 (trifluridine/tipiracil) is an antineoplastic agent that is non-cross resistant with 5-fluorouracil and capecitabine and that has a different toxicity profile. This study evaluated the safety of TAS-102...
