Purpose: Despite the fact that r-hGH was first approved for use by FDA in 1995 and the conventional dosage form in the market has a limitation of daily subcutaneous injections, there remains a lack of sustained delivery system in the market. Nutropin depot, a long-acting dosage form of r-hGH was approved for marketing by FDA in 1999, however, it was discontinued in 2004. Since then, unabating efforts have been made to develop biodegradable polymer based formulations for r-hGH delivery.

Article Synopsis
  • The study focuses on the eukaryotic microbe's autocrine proliferation repressor protein A (AprA), which inhibits cell growth and acts as a chemorepellent.
  • Researchers discovered that the receptor for AprA is likely the G protein-coupled receptor GrlH, as cells lacking GrlH show rapid growth and reduced sensitivity to AprA.
  • The findings suggest that G protein-coupled receptors play a role in both sensing cell density and mediating movement away from repellant signals, shedding light on eukaryotic cell communication and organization.

Structure Optimization of Aloperine Derivatives as HIV-1 Entry Inhibitors.

ACS Med Chem Lett

November 2017

Department of Surgery, Duke University Medical Center, Durham, North Carolina 27710, United States.

As a step toward developing novel anti-HIV agents, we have identified a class of quinolizidines, including aloperine, that inhibit HIV at 1-5 μM by blocking viral entry. In this study, we have optimized the structure of aloperine and derived compounds with markedly improved activity. Our structural optimization has yielded an aloperine derivative with approximately a 15-fold increase in anti-HIV-1 activity.

Endothelial cell (EC) branching is critically dependent upon the dynamic nature of the microtubule (MT) cytoskeleton. Extracellular matrix (ECM) mechanosensing is a prominent mechanism by which cytoskeletal reorganization is achieved; yet how ECM-induced signaling is able to target cytoskeletal reorganization intracellularly to facilitate productive EC branching morphogenesis is not known. Here, we tested the hypothesis that the composition and density of the ECM drive the regulation of MT growth dynamics in ECs by targeting the MT stabilizing protein, cytoplasmic linker associated protein 1 (CLASP1).

Recent Genome-wide Association Studies (GWASs) for eye diseases/traits have delivered a number of novel findings across a diverse range of diseases, including age-related macular degeneration (AMD), glaucoma and refractive error. However, despite this astonishing rate of success, the major challenge still remains to not only confirm that the genes implicated in these studies are truly the genes conferring protection from or risk of disease but also to define the functional roles these genes play in disease. Ongoing evidence is accumulating that the single nucleotide polymorphisms (SNPs) used in GWAS and fine mapping studies have causal effects through their influence on gene expression rather than affecting protein function.

N-methyl-d-aspartate receptors (NMDARs) are expressed abundantly in the brain and play an important role in the regulation of neuronal development, learning, memory, neurodegenerative diseases, and neurogenesis, all of which are extensively discussed in reviews published elsewhere. While the number of research articles on the developmental and neurological cues that trigger NMDAR localization across a developing neuron and the role of the NMDAR in embryonic and adult stem cell proliferation and differentiation have been growing dramatically over the past few years, there is not a single review on this latter general topic. In the proposed review, we will summarize the current understanding of NMDARs in stem cell biology and their involvement in pathophysiological processes of neuron development, especially during early neuronal development (immature neurons) and differentiation.

Using simulations of Mn/Fe K-edge X-ray absorption spectroscopy (XAS), combined with DFT-optimized structural models and direct comparisons with available experimental data, we determine geometrical and electronic properties of the Mn-Fe active site of Chlamydia trachomatis (Ct) of ribonucleotide reductase (RNR). In the post-edge XAS energy range, we use extended X-ray absorption fine structure (EXAFS) data, to acquire absorber-scatterer geometrical information around each absorber metal center. For this task, we apply a protocol that evaluates Debye-Waller factors in scattering paths instead of scattering shells to fit the experimental EXAFS.

Compliance and dimensionality mechanosensing, the processes by which cells sense the physical attributes of the extracellular matrix (ECM), are known to drive cell branching and shape change largely through a myosin-II-mediated reorganization of the actin and microtubule (MT) cytoskeletons. Subcellular regulation of MT dynamics is spatially controlled through a Rac1-Aurora-A kinase pathway that locally inhibits the MT depolymerizing activity of mitotic centromere-associated kinesin (MCAK), thereby promoting leading-edge MT growth and cell polarization. These results suggest that the regulation of MT growth dynamics is intimately linked to physical engagement of the cell with the ECM.

Evaluation of the ADHD Rating Scale in Youth with Autism.

J Autism Dev Disord

January 2017

Center for Autism Research, The Children's Hospital of Philadelphia, 3535 Market Street, Ste 860, Philadelphia, PA, 19104, USA.

Scientists and clinicians regularly use clinical screening tools for attention deficit/hyperactivity disorder (ADHD) to assess comorbidity without empirical evidence that these measures are valid in youth with autism spectrum disorder (ASD). We examined the prevalence of youth meeting ADHD criteria on the ADHD rating scale fourth edition (ADHD-RS-IV), the relationship of ADHD-RS-IV ratings with participant characteristics and behaviors, and its underlying factor structure in 386, 7-17 year olds with ASD without intellectual disability. Expected parent prevalence rates, relationships with age and externalizing behaviors were observed, but confirmatory factor analyses revealed unsatisfactory fits for one-, two-, three-factor models.

The physiological process by which new vasculature forms from existing vasculature requires specific signaling events that trigger morphological changes within individual endothelial cells (ECs). These processes are critical for homeostatic maintenance such as wound healing, and are also crucial in promoting tumor growth and metastasis. EC morphology is defined by the organization of the cytoskeleton, a tightly regulated system of actin and microtubule (MT) dynamics that is known to control EC branching, polarity and directional migration, essential components of angiogenesis.

Autophagy- An emerging target for melanoma therapy.

F1000Res

September 2016

Melanoma Research Center, Wistar Institute, Philadelphia, PA, USA.

Melanoma accounts for only 5% of all cancers but is the leading cause of skin cancer death due to its high metastatic potential. Patients with metastatic melanoma have a 10-year survival rate of less than 10%. While the clinical landscape for melanoma is evolving rapidly, lack of response to therapies, as well as resistance to therapy remain critical obstacles for treatment of this disease.

Relationship Between Walking Capacity, Biopsychosocial Factors, Self-efficacy, and Walking Activity in Persons Poststroke.

J Neurol Phys Ther

October 2016

Department of Physical Therapy (K.A.D., T.R.W., D.S.R.), Biomechanics and Movement Science Program (D.S.R.), and Biostatistics Core Facility (R.T.P.), University of Delaware, Newark; and Department of Physical Therapy (M.R.), University of the Sciences in Philadelphia, Philadelphia, Pennsylvania.

Background/purpose: Many factors appear to be related to physical activity after stroke, yet it is unclear how these factors interact and which ones might be the best predictors. Therefore, the purpose of this study was twofold: (1) to examine the relationship between walking capacity and walking activity, and (2) to investigate how biopsychosocial factors and self-efficacy relate to walking activity, above and beyond walking capacity impairment poststroke.

Methods: Individuals greater than 3 months poststroke (n = 55) completed the Yesavage Geriatric Depression Scale (GDS), Fatigue Severity Scale (FSS), Modified Cumulative Illness Rating (MCIR) Scale, Walk 12, Activities-Specific Balance Confidence (ABC) Scale, Functional Gait Assessment (FGA), and oxygen consumption testing.

Article Synopsis
  • Interstitial renal fibrosis is a significant issue in Chronic Kidney Disease and diabetic nephropathy, where adenosine signaling plays a crucial role in the disease's progression.
  • Research using the NRK-49F renal fibroblast cell line shows that only adenosine receptors A1 and A2B are present under normal conditions, with A2B enhancing cAMP levels while A1 inhibits it.
  • Activation of the A2B receptor leads to increased levels of pro-fibrotic and inflammatory markers, suggesting that adenosine signaling contributes to the activation of fibroblasts, promoting further renal damage.
