Although HepG2 cells are widely used in drug discovery, their 2D cultures exhibit low expression of drug-metabolizing enzymes such as cytochrome P450s (CYPs), limiting utility for toxicity and pharmacokinetic studies. Nano-fibrillated bacterial cellulose (NFBC) is a unique biomaterial that features exceptional homogeneity, high purity, and excellent biocompatibility. We recently employed two NFBC-based 3D culture systems: the Suspension and the OnGel methods. However, the capacity of NFBC to improve hepatocyte-specific functions has yet to be systematically explored. In this study, we aimed to establish a 3D culture platform for HepG2 cells using NFBC to restore hepatic functionality, and drug-metabolizing activity in particular, via comparison with conventional 2D monolayers. Both of these 3D culture systems produced viable HepG2 spheroids with good proliferation. Exploratory microarray profiling suggested broad upregulation of multiple absorption, distribution, metabolism and excretion (ADME) genes in the HepG2 spheroids. Among these, the enzyme Cytochrome P450 3A4 (CYP3A4) showed a significant increase in protein expression and in enzymatic activity in the HepG2 spheroids, which was functionally confirmed by acetaminophen (APAP) toxicity via its bioactivation into toxic metabolite. In addition, the HepG2 spheroids displayed reduced sensitivity to the anticancer drug doxorubicin compared to 2D monolayer. Collectively, these findings demonstrate that NFBC-based 3D culture systems effectively restore liver-specific functions in HepG2 cells, which results in HepG2 spheroids with metabolic competence and physiologically relevant drug responses, and could offer a promising tool for high-throughputin vitrodrug screening.","ja":"Three-dimensional (3D) culture more faithfully reproducesin vivo-like cell interactions and functions than conventional two-dimensional (2D) monolayers.

A gradual decrease of anti-PEG antibody titers from baseline was observed after PEG-G-CSF administration. Of the 19 participants, 10 were assessed for noninfectious fever after the first administration of PEG-G-CSF and three experienced this reaction. The receiver operating characteristic curve revealed that the cut-off values of pretreated anti-PEG IgM and IgG titers for noninfectious fever were set at 5.0 and 96.6 U/mL, respectively. All patients who experienced noninfectious fever had anti-PEG antibody titers above this cut-off value (P = .033). An enzyme-linked immunosorbent assay revealed that some anti-PEG antibodies in patients with anti-PEG antibody titers above the cut-off value reacted with the PEGylated liposome. These results indicate the reactivity of the anti-PEG antibodies to PEGylated therapeutics observed in hematologic patients and the possibility of the relationship between high titers of anti-PEG antibodies and the development of adverse events after PEG-G-CSF administration."},"publication_date":"2023-01-28","publication_name":{"en":"Clinical Pharmacology in Drug Development","ja":"Clinical Pharmacology in Drug Development"},"volume":"12","number":"8","starting_page":"826","ending_page":"831","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1002/cpdd.1225"],"issn":["2160-7648"]},"published_paper_type":"scientific_journal"},"priority":"input_data"} line:10, {"insert":{"user_id":"7000022165","type":"published_papers","id":"33577516"},"force":{"see_also":[{"@id":"https://tokushima-u.repo.nii.ac.jp/records/2009199","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=381696","label":"url"}],"paper_title":{"en":"Efficient construction of the hexacyclic ring core of palau'amine: the pKa concept for proceeding with unfavorable equilibrium reactions","ja":"Efficient construction of the hexacyclic ring core of palau'amine: the pKa concept for proceeding with unfavorable equilibrium reactions"},"authors":{"en":[{"name":"Ohashi Eisaku"},{"name":"Karanjit Sangita"},{"name":"Nakayama Atsushi"},{"name":"Takeuchi Kohei"},{"name":"Emam E Sherif"},{"name":"ANDO Hidenori"},{"name":"Ishida Tatsuhiro"},{"name":"Namba Kosuke"}],"ja":[{"name":"大橋 栄作"},{"name":"カランジット サンギータ"},{"name":"中山 淳"},{"name":"竹内 公平"},{"name":"Sherif Emam Abdallah Emam"},{"name":"安藤 英紀"},{"name":"石田 竜弘"},{"name":"難波 康祐"}]},"publication_date":"2021-08-11","publication_name":{"en":"Chemical Science","ja":"Chemical Science"},"volume":"12","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1039/D1SC03260G"],"issn":["2041-6539"]},"published_paper_type":"scientific_journal"},"priority":"input_data"} line:11, {"insert":{"user_id":"7000022165","type":"published_papers","id":"30512778"},"force":{"see_also":[{"@id":"https://www.ncbi.nlm.nih.gov/pubmed/32700691","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=366739","label":"url"}],"paper_title":{"en":"Utilization of Click Chemistry to Study the Effect of Poly(ethylene) Glycol Molecular Weight on the Self-Assembly of PEGylated Gambogic Acid Nanoparticles for the Treatment of Rheumatoid Arthritis","ja":"Utilization of Click Chemistry to Study the Effect of Poly(ethylene) Glycol Molecular Weight on the Self-Assembly of PEGylated Gambogic Acid Nanoparticles for the Treatment of Rheumatoid Arthritis"},"authors":{"en":[{"name":"Nguyen A"},{"name":"ANDO Hidenori"},{"name":"Böttger R"},{"name":"Viswanadham K K"},{"name":"Rouhollahi E"},{"name":"Ishida Tatsuhiro"},{"name":"Li S"}],"ja":[{"name":"Nguyen A"},{"name":"安藤 英紀"},{"name":"Böttger R"},{"name":"Viswanadham K K"},{"name":"Rouhollahi E"},{"name":"石田 竜弘"},{"name":"Li S"}]},"description":{"en":"Many small-molecule drugs exhibit poor aqueous solubility, and various approaches have been developed to improve their solubility and delivery.

In this study, we employed a click chemistry platform to robustly conjugate short-chain methoxypolyethylene glycol (mPEG) of three different molecular weights to a small molecule anti-inflammatory drug, gambogic acid (GA), and studied the SAR. NPs formed with mPEG550 and mPEG5000, referred to as NP-550 and NP-5000, respectively, had larger mean diameters (130.0 ± 16.9 nm and 143.0 ± 0.1 nm, respectively) and higher critical micellar concentrations (CMCs, 9.5 μg mL-1 and 10.5 μg mL-1, respectively) compared to NPs formed with mPEG2000 (NP-2000, mean diameter = 97.8 ± 5.0 nm and CMC = 6.6 μg mL-1). NP-2000 and NP-5000 did not cause significant hemolytic toxicity, whereas NP-550 and free GA induced 90% and 60% hemolysis, respectively. NP-2000 was selected for further studies due to its improved safety, small size and low CMC. In cultured inflammatory macrophages, NP-2000 exhibited activity comparable to free GA in suppressing tumor necrosis factor-α.

We have developed a new liposomal preparation of oxaliplatin (l-OHP), an important anti-tumor drug for treatment of colorectal cancer, using PEGylated liposomes (Lipo-l-OHP), and showed that Lipo-l-OHP exhibits increased anti-tumor activity in tumor-bearing mice compared to the original preparation of l-OHP.

Administration of Lipo-l-OHP promoted accumulation of platinum in rat hind paws, however, it caused negligible morphological and histological alterations on the plantar surface of the paws.
