Abstract:

The Cauchy-Dirichlet problem of the Helmholtz equation yields unstable solution, which when solved with the Quasi-Boundary Value Method (Q-BVM) for a regularization parameter = 0. At this point of regularization parameter, the solution of the Helmholtz equation with both Cauchy and Dirichlet boundary conditions is unstable when solved with the Q-BVM. Thus, the quasi-boundary value method is insufficient and inefficient for regularizing ill-posed Helmholtz equation with both Cauchy and Dirichlet boundary conditions. In this paper, we introduce an expression 1 (1+ 2) ; ∈ R, where is the regulari

Abstract:

Second Clement suffers from a lack of clarity about its historical and literary contexts. The anonymous text’s date and provenance have defied precise determination and, although it is referred to a few times in the history of tradition, it seems not to be cited at all. Moreover, its first two verses maintain a history of translation into modern languages employing expressions long out of date. The word, μικρά occurs four times in the first two verses, twice as part of the expression, μικρὰ φρονεῖν. This article identifies the outmoded nature of current translations of these words and proposes

Abstract:

Hypertensive mice that express the human renin and angiotensinogen genes are used as a model for human hypertension because they develop hypertension secondary to increased renin-angiotensin system activity. Our study investigated the cellular localization and distribution of COX-1, COX-2, mPGES-1, and mPGES-2 in organ tissues from a mouse model of human hypertension. Male (n=15) and female (n=15) double transgenic mice (h-Ang 204/1 h-Ren 9) were used in the study. Lung, kidney, and heart tissues were obtained from mice at necropsy and fixed in 10%neutral buffered formalin followed by embeddin

A main clinical parameter of COVID-19 pathophysiology is hypoxia. Here we show that hypoxia decreases the attachment of the receptor binding domain (RBD) and the S1 subunit (S1) of the spike protein of SARS-CoV-2 to epithelial cells. In Vero E6 cells, hypoxia reduces the protein levels of ACE2 and neuropilin-1 (NRP1), which might in part explain the observed reduction of the infection rate. In addition, hypoxia inhibits the binding of the spike to NCI-H460 human lung epithelial cells by decreasing the cell surface levels of heparan sulfate (HS), a known attachment receptor of SARS-CoV-2.

Matrix Metallopeptidase 1 (MMP-1) expression has repeatedly been correlated to tumorigenesis and metastasis. Yet, MMP-1 regulation in a metastatic context remains largely unknown.

We show that MMP-1 expression is regulated by an AP-1 element in its promoter in highly metastatic MDA-MB-231 mammary carcinoma cell derivatives. Fra-1, an AP-1 family transcription factor, differentially binds this element in highly metastatic cells compared to low metastatic cells and is required for MMP-1 ex

The pituitary-specific, POU-homeodomain factor GHF-1/Pit-1 is necessary, but not sufficient, for cell-specific expression of prolactin (PRL), growth hormone (GH), and thyrotropin. Combinatorial interactions of GHF-1 with other factors are likely to be required; however, such factors and their mechanisms of action remain to be elucidated. Here we identify Ets-1 as a factor that functionally and physically interacts with GHF-1 to fully reconstitute proximal PRL promoter activity. In contrast, Ets-2 has no effect, and the alternatively spliced GHF-2/Pit-1beta variant fails to synergize with Ets-1

Abstract:

Raf-1, a multifunctional kinase, regulates various cellular processes, including cell proliferation, apoptosis, and migration, by phosphorylating MAPK/ERK kinase and interacting with specific kinases. Cellular Raf-1 activity is intricately regulated through pathways involving the binding of regulatory proteins, direct phosphorylation, and the ubiquitin–proteasome axis. In this study, we demonstrate that PHI-1, an endogenous inhibitor of protein phosphatase-1 (PP1), plays a pivotal role in modulating Raf-1 proteostasis within cells.

Abstract:

Programmed cell death protein 1 (PD-1) blockade targeting the PD-1 immune checkpoint has demonstrated unprecedented clinical efficacy in the treatment of advanced cancers including hematologic malignancies. This article reviews the landscape of PD-1/programmed death-ligand 1 (PD-L1) expression and current PD-1 blockade immunotherapy trials in B-cell lymphomas. Most notably, in relapsed/refractory classical Hodgkin lymphoma, which frequently has increased PD-1+ tumor-infiltrating T cells, 9p24.1 genetic alteration, and high PD-L1 expression, anti-PD-1 monotherapy has demonstrated remarkable obj

Abstract:

Antisense protein of Human T-cell Leukemia Virus Type 2 (HTLV-2), also called APH-2, negatively regulates the HTLV-2 and helps the virus to maintain latency via scheming the transcription. Despite the remarkable occurrence of HTLV-2/HIV-1 co-infection, the role of APH-2 influencing HIV-1 replication kinetics is poorly understood and needs investigation. In this study, we investigated the plausible role of APH-2 regulating HIV-1 replication. Herein, we report that the overexpression of APH-2 not only hampered the release of HIV-1 pNL4.3 from 293T cells in a dose-dependent manner but also affect

Abstract:

Stanniocalcin-1 (STC1) is an endocrine hormone originally discovered in the corpuscles of Stannius, endocrine glands on kidneys of bony fishes, and also has been identified in mammals. The mammalian STC1 gene is widely expressed in various tissues and appears to be involved in diverse biological processes. There is growing evidence to suggest that altered patterns of gene expression have a role in human cancer development. Recently STC1 has been identified as a stimulator of mitochondrial respiration and has been hypothesized to be functionally related to the Warburg effect, of which hypoxia-i

Abstract:

ABSTRACT The insulin receptor substrate (IRS) proteins are cytoplasmic adaptors that organize signaling complexes downstream of activated cell surface receptors. Here, we show that IRS-1 and IRS-2, despite significant homology, play critical yet distinct functions in breast cancer, and we identify specific signaling pathways that are influenced by IRS-1 using the polyoma virus middle-T (PyV-MT) transgenic mouse model of mammary carcinoma and Irs-1 null (Irs1 −/−) mice. The absence of Irs-1 expression enhanced metastatic spread significantly without a significant effect on primary tumor growth.

Abstract:

Abstract Commitment of multipotential hematopoietic progenitors to unique cell fates is determined by the induction and interplay of specific nuclear factors that reinforce unilineage transcriptional programs. Previously, we reported that loss of transcription factor GATA-1 promotes the expansion of bipotential megakaryocyte erythroid progenitors (MEPs) from embryonic stem cell or fetal liver derived hematopoietic progenitors. These mutant cells, termed G1ME (for Gata-1− Megakaryocyte-Erythroid), proliferate in culture and differentiate into committed megakaryocytes and erythroblasts when GATA

Diabetes mellitus (DM) type 2 is a metabolic disorder with the occurrence of insulin receptor resistance and reduced ability of pancreatic β-cells to secrete insulin, there will be an increase in adipose tissue which causes hypertrophy and hyperplasia. This situation triggers inflammation involving the role of pro-inflammatory cytokines and chemokines such as TNF-α (Tumor Necrosis Factor-Alpha) and MCP-1 (Monocyte Chemotactic Protein-1).

ABSTRACT Caveolin-1 (Cav-1) is a major protein constituent of caveolae, a type of plasma membrane raft. We observed that coexpression of human Cav-1 with human immunodeficiency virus type 1 (HIV-1) blocked virion production from cells that are ordinarily highly permissive. Further investigation showed that this effect is specific, occurs at low ratios of Cav-1 to HIV-1 DNA, depends on expression of Cav-1 protein, and involves severely impaired expression of HIV-1 proteins. Cav-1 also blocked HIV-2 expression. In contrast, Cav-1 did not inhibit protein expression by a paramyxovirus and did not

The abilities of IRS-1−/− cells and IRS-2−/− cells to differentiate into adipocytes are approximately 60 and 15%, respectively, lower than that of wild-type cells, at day 8 after induction an

ABSTRACT Shiga toxins (Stxs), which are proteins expressed by the enteric pathogens Shigella dysenteriae serotype 1 and some serotypes of Escherichia coli, are potent protein synthesis inhibitors. Stx-producing organisms cause bloody diarrhea with the potential to progress to acute renal failure and central nervous system complications. Studies using animal models of these diseases have shown that Stxs are major virulence factors, and purified toxins have been shown to be capable of killing many types of cells in vitro. We showed that Stx type 1 (Stx1) rapidly induced apoptosis in undifferenti
