    BIOCELL, Vol.47, No.11, pp. 2361-2383, 2023, DOI:10.32604/biocell.2023.031063

    Abstract Cardiovascular diseases (CVDs) are the leading cause of death globally. CVDs are a group of disorders of the heart and blood vessels and include coronary heart disease, cerebrovascular disease and rheumatic heart disease among other conditions. There are multiple independent risk factors for CVD, including hypertension, age, smoking, insulin resistance, elevated low-density lipoprotein cholesterol (LDL-C) levels, and triglyceride levels. LDL-C levels have traditionally been the target for therapies aimed at reducing CVD risk. High density lipoprotein (HDL) constitutes the only lipoprotein fraction with atheroprotective functions. Early HDL-targeted therapies have focused on increasing HDL-C levels. However, clinical trials have shown that… More > Graphic Abstract

    HUI LI1, CHENGFANG ZHOU2, MEI KUANG2, YUN LIU1,*, JIEPING CHEN1,2,*

    BIOCELL, Vol.47, No.10, pp. 2177-2186, 2023, DOI:10.32604/biocell.2023.029373

    Abstract Fizzy-related protein homolog 1 (FZR1) mainly functions as a specific activator of the anaphase-promoting complex/cyclosome (APC/C) in the cell cycle and controls the G0 and G1 phases of the cell cycle. We highlight recent work that has studied the role of FZR1 in tumorigenesis, growth, differentiation, and genome stability through cell-cycle control. We summarize the current state of knowledge regarding FZR1 structure, function, and the distinct ways of APC/C dysregulation in solid tumors and hematologic malignancies. We also discuss novel approaches for targeting the FZR1 as a cancer therapy and research area for future work. More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 1921-1941, 2023, DOI:10.32604/phyton.2023.027810

    Abstract

    One of the main reasons of the annual reduction in plant production all around the world is the occurrence of abiotic stresses as a result of an unpredicted changes in environmental conditions. Abiotic stresses basically trigger numerous pathways related to oxygen free radicals’ generation resulting in a higher rate of reactive oxygen species (ROS) production. Accordingly, higher rate of oxygen free radicals than its steady state causes to oxidize various types of molecules and compartments within the plants’ cells and tissues. Oxidative stress is the result of high amount free radicals of oxygen interfering with different functions leading to undergo… More >

    Yu Sun, Wei Wang, Chenghai Zhao

    Oncology Research, Vol.28, No.6, pp. 661-674, 2020, DOI:10.3727/096504020X16014648664459

    Abstract Wnt molecules play crucial roles in development and adult homeostasis through their receptors Frizzled proteins (Fzds). Fzds mediate canonical b-catenin pathway and various noncanonical b-catenin-independent pathways. Aberrant Fzd signaling is involved in many diseases including cancer. Wnt/b-catenin is a well-established oncogenic pathway involved in almost every aspect of tumor development. However, Fzd-mediated noncanonical Wnt pathways function as both tumor promoters and tumor suppressors depending on cellular context. Fzd-targeted therapies have proven to be effective on cultured tumor cells, tumor cell xenografts, mouse tumor models, and patient-derived xenografts (PDX). Moreover, Fzd-targeted therapies synergize with chemotherapy in preclinical models. However, the occurrence… More >
