Currently, the selenium-doped hydroxyapatite (Se-HAp) nanoparticles have received immense therapeutic and tissue repairing values owing to their antitumor activities. However, a high concentration of Se is toxic towards normal and stem cells whereas its low concentration cannot effectively remove the cancer cells. Therefore, the current study was aimed to improve the anticancer activity of Se-HAp nanoparticles through catechins (CC) modification owing to their high cancer therapeutic value. The sequentially developed catechins modified Se-HAp nanocomposites (CC/Se-HAp) were characterized for various physicochemical propert...

Authors: Zhang J, Miao Y, Ni W, Xiao H, Zhang J Abstract Photothermal therapy (PTT) is a rapidly developing approach for cancer therapy, which has been widely recognized to exert high efficacy as compared to chemotherapy. However, the limited tumour homing property of currently available drug delivery systems (DDSs) is the bottleneck for the efficient delivery of photothermal agents. Here in this study, we surface modified silica nanoparticles (SLN) with the cell membrane (CM) derived from 143B cells to construct a platform (CM/SLN) capable of targeting the homogenous 143B cells. In addition, indocyanine green (ICG...

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Authors: De Marinis F, Barberis M, Barbieri V, Marchianò A, Gasparini S, Migliorino MR, Romano G, Spinnato F, Vitiello F, Gridelli C Abstract INTRODUCTION: In the era of personalized cancer therapy, the sampling of adequate tumor tissue for histologic diagnosis and genomic profiling is crucial, not only at the initial diagnosis but also in the event of resistant and recurrent disease when sequential biopsies may be required to evaluate somatic mutations and histologic changes. Areas covered: The identification of genetic driver alterations led to the selection of patients who are most likely to benefit from ...

This study investigated the cytotoxicity of Mg and Mg ‐Ti microparticles to human osteosarcoma cells. Osteosarcoma cells were killed in a dosage‐dependent manner when cells, with a cell seeding density of 30,000 cells/cm2, were cultured with 0 to 2500 µg/mL of Mg or Mg‐Ti in cell culture media for 24–72 h. Mg‐Ti killed cells more effectively, where 1250 µg/mL of Mg‐Ti killed cells completely by 24 h, while 2500 µg/mL of Mg killed nearly all cells, but not all. Killing due to particle corrosion occurred mostly during the first 24 h, and so the percent cell viability between 24 and 72 h show...
