The modulation of immature dendritic cells (iDCs), which involves processes such as phagocytosis, migration, and maturation, is considered a beneficial research theme. Once activated by an antigen, iDCs turn to mature DCs (mDCs) and migrate towards secondary lymphoid organs, and initiate the progress of cellular immunity. Histone deacetylase inhibitors (HDACis) are also thought to be a major modulator of cellular immunity. Herein, we demonstrate that HDACis (trichostatin-A (TSA), sodium butylate (SB), scriptaid (ST)) play a central regulatory role in the migratory activity of iDCs. In our results, TSA, SB and ST showed the potent inhibitory effect on the migration of iDCs stimulated by MIP-1α. The inhibitory activities of HDACis were found to be caused by reduction of CCR1 expression on the cell surface, and by the inhibition of phosphorylation of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases 1 and 2 (ERK 1/2), and c-Jun N-terminal kinase (JNK).

Due to the lack of effective therapeutic approach, glioblastoma (GBM) remains one of the most malignant brain tumour. By in vitro investigations on primary GBM stem cells, we highlighted one of the underlying mechanisms of drug resistance to alkylating agents, the DNA damage responses. Here, flow cytometric analysis and viability and repopulation assays were used to assess the long-term cytotoxic effect induced by the administration of a fourth-generation platinum prodrug, the (OC-6-44)-acetatodiamminedichlorido(2-(2-propynyl)octanoato) platinum(IV) named Pt(IV)Ac-POA, in comparison to the most widely used Cisplatin.

Doxorubicin (DOXO) has long been used clinically and remains a key drug in cancer therapy. DOXO-induced cardiomyopathy (DICM) is a chronic and fatal complication that severely limits the use of DOXO. However, there are very few therapeutic agents for DICM, and there is an urgent need to identify those that can be used for a larger number of patients.

Graduate Division of Nutritional and Environmental Sciences, University of Shizuoka, Yada 52- 1, Suruga-ku, Shizuoka, 422-8526, Japan.

Background: Skin is exposed to various environmental factors throughout life, and some of these factors are known to contribute to skin aging. Long-term solar UV exposure is a well-known cause of skin aging, as is cigarette smoke, which contains a number of chemicals. In this study, combined effect of UVA and cigarette sidestream smoke (CSS) on matrix metalloproteinase-1 (MMP-1) induction was investigated.

The death of osteoblasts induced by glucocorticoid (GC)-mediated oxidative stress plays a crucial role in the development of steroid-induced osteonecrosis of the femoral head (SIONFH). Improving bone formation driven by osteoblasts has shown promising outcomes in the prognosis of SIONFH. Isovitexin has demonstrated antioxidant properties, but its therapeutic effects on GC-induced oxidative stress and SIONFH remain unexplored.
