The
Journal of Cellular Biotechnology is a peer-reviewed international journal for advancing research activities in the field of cellular biotechnology. It serves as a medium for the publication of full papers, invited reviews, short communications, technical notes and letters to the Editor-in-Chief on all aspects of cellular biotechnology. This comprises molecular biological topics covering biochemical, chemical, pharmacological or bioprocess engineering aspects, as well as the development of novel biomaterials. Therefore, cellular biotechnology differs from biology, biochemistry, and other basic life sciences by its emphasis on using the knowledge of bioscience to solve important practical problems. Papers presenting information of a multidisciplinary nature - not suitable for publication in a journal devoted to a single discipline - are particularly welcome.
Manuscripts submitted for the
Journal of Cellular Biotechnology are expected to cover activities related to molecular diagnostics, the expansion of human primary cells for individualized therapies or drug testing, 2- and 3-dimensional co-culture techniques, cell line validation, tissue engineering, and stem cell biology for the treatment of human pathologies. This includes studies on the design of reactors and research on cellular biology and physiology of mammalian cells in vitro and in vivo, and tissue. Of special interest is the rational manipulation of reactions through metabolic engineering techniques or specific reactor operations that lead to biomaterials with unique properties. Also, biochemical and physiological studies of metabolism and enzymes as relevant for tissue culture cells, investigations at the molecular level including transcription/translation control; design and engineering of products by molecular strategies; engineering of cellular modification and transport systems such as post-translational protein modifications as well as protein and metabolite secretion; molecular strategies of screening for new or modified products (e.g. pharmaceuticals or bioactive compounds). In addition, investigations in preclinical animal experiments are welcome.
The endeavour of the Editor-in-Chief and publisher of the
Journal of Cellular Biotechnology is to bring together contributions from those working in various fields related to cell-cell or cell-material interactions all over the world. The editorial board members of the
Journal of Cellular Biotechnology are from those countries in Europe, Asia, Australia and America where appreciable work in cellular biotechnology is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He/she is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Abstract: BACKGROUND, Different preservation media used on fish samples may influence the digestion of organic matter for microplastic (MP) particle detection. Comparison of fresh and conserved fish is thereby problematic. OBJECTIVE, For quality assurance purposes and comparability of MP research, a method for digestion of preserved tissue like intestine with little impact on most MP particles was implemented. METHODS, Conserved fish samples were digested using SDS, KOH and Fenton’s reagents. The effect of the different chemicals used on different MP particles was then analyzed using Raman hit quality. Therefore, different filter materials were investigated using PMMA particles.…RESULTS, Moist grided nitrocellulose filter was found best suited for this study. The effects of this digestion protocol on different polymer particles differed among polymers. Two of the used polymer particles dissolved during SDS + KOH treatment. PVC hard showed the highest loss of Raman hit quality (29.5 %). Some fish showed residues of sand or chitin from insects depending on their feeding strategy which could not be digested using this protocol. CONCLUSION, Not every polymer could be detected reliably using this protocol. For residues like sand or chitin, a density separation and enzymatic chitin degradation using chitinase may be needed, which could be implemented into this protocol.

Abstract: Coronary atherosclerotic heart disease is an important threat to human health. The pathological basis is atherosclerosis, and foam cell formation is the key link in the initiation of atherosclerosis. Here, foam cell models were established using 50 ng/ml oxidized low-density lipoprotein (ox-LDL) to stimulate in vitro cultures of THP-1 cells for 72 h. The expression of ZNF580, a Cys2–His2 (C2H2) zinc finger protein containing 172 amino acids that was originally cloned by screening a human aortic cDNA library, was measured in foam cells, and its interaction with various regulatory factors during foam cell formation was investigated. Oil red O (ORO) staining…was used to observe cell morphology and intracellular lipid levels. Lentivirus transfection was used to induce high ZNF580 expression (Ad-ZNF580) and low ZNF580 expression (Si-ZNF580) in THP-1 cells, and a fluorescent inverted microscope was used to observe the distribution of ZNF580 immunofluorescence to deduce the transfection rate. RNA and total protein were extracted, and the expression levels of ZNF580, cluster of differentiation 36 (CD36), peroxisome proliferator activated receptor-γ (PPAR-γ), ATP-binding cassette transporter A1 (ABCA1) and apolipoprotein E (ApoE) were measured by real-time quantitative PCR. The protein levels were examined by western blotting to evaluate the interaction between ZNF580 and associated regulatory factors. ZNF580 can significantly increase the expression levels of ApoE and ABCA1 and significantly decrease the expression levels of CD36 and PPAR-γ, suggesting that ZNF580-mediated inhibition of foam cell formation is associated with the PPAR-γ-CD36 signalling pathway. Based on these findings, ZNF580 might be a potential therapeutic candidate for the treatment of coronary atherosclerotic heart disease.

Abstract: Enamel Matrix Derivatives (EMD) is a novel biomaterial that has been discovered in the late ’90 s and has found numerous uses in the field of periodontics. It is mainly used in areas that require natural regeneration and healing. It has found applications in other branches of dentistry, such as; wound healing, regenerative procedures, endodontics, pedodontics, and others. It mainly consists of amelogenins and other proteins such as amelin, enamelin, tufetelin etc. It is known to increase cementogenesis and improve periodontal attachment. The amount of research done on this product is very little and very scattered. The maximum amount of research…has been done regarding its use in periodontic surgery and other related procedures since it had been initially discovered as a material that would increase periodontal attachment. Given its various biological properties, it is safe to say that it has the potential to succeed in other branches. Our review, therefore, aims to collect and present the research performed and ongoing research potential regarding EMD products, which are now available in a gel-based form known as Emdogain.

Abstract: Bacteria may develop antibiotic resistance due to unintentional DNA alterations that give them a survival advantage. Bacteria may develop antibiotic resistance due to unintentional DNA alterations that give them a survival advantage. Finding genetic changes and understanding how they enable bacteria to withstand antibiotic attacks will be crucial to our ability to develop new medications to combat them.
