Mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. Several recombinant protein systems have been introduced to the market, most of which are under clinical development. In spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...

We present familial tuberous sclerosis (TS) case complicated by COVID-19. COVID-19 aggravates the course of TS and may lead to a fatal outcome. review role mTORC1 (mechanistic/mammalian Target Rapamycin Complex 1) in development functions nervous system pathogenesis with emphasis on involvement brain lungs. observed that worsens epilepsy patients TS. In patients, lymphangioleiomyomatosis predis...

Blood development has been highly conserved during evolution. Hematopoietic cells in amphibian and fish embryos, as in mammalian embryos, emerge and progressively differentiate in several locations. Hematopoiesis, including of the immune system, is similar in the amphibian, Xenopus, to mammals and the embryos are ideal for tissue transplantation and lineage labelling experiments, which have ena...

To explore the mechanism of microRNA-125a reversing resistance laryngeal cancer stem cells to cisplatin from mitochondrial autophagy. The human carcinoma cell line Hep-2 was purchased Shanghai Bioleaf Biotechnology Co., Ltd. expression messenger RNA in each group analyzed by reverse transcription-polymerase chain reaction. migration and invasion ability evaluated Transwell assay. Cell apoptosis...

hepcidin is an innate immune element which decreases the iron absorption from diet and iron releasing from macrophage cell. in contrast to the chemical iron chelators, there has been limited effort applied to the specific use of hepcidin as a new drug for decreasing the iron overload. hepcidin is produced in different biological systems. for instance, e-coli is used for human hepcidin expressio...

epidermal growth factor (egf), a growth factor involved in cell growth and differentiation, is a small polypeptide with molecular weight of approximately 6 kda known to be present in a number of different mammalian species. experimental studies in animals and humans have demonstrated that the topical application of egf accelerates the rate of epidermal regeneration of partial-thickness wounds a...

For protein production and purification, many different cell systems ranging from bacteria to mammalian cell lines are commonly used. High-level expression of recombinant proteins in E. coli is often achieved using the strong yet tightly regulatable T7 promoter system (23). Many convenient T7 promoter-based bacterial expression vectors are commercially available from different sources and are w...

Objective(s): Filamentous bacteriophage M13 was genetically engineered to specifically target mammalian cells for gene delivery purpose. Materials and Methods: A vascular endothelial growth factor receptor 2 (VEGFR2)-specific nanobody was genetically fused to the capsid gene III of M13 bacteriophage (pHEN4/3VGR19). A mammalian expression construct containing Cop-green fluorescent protein (Cop-G...
