Doxorubicin-loaded functionalized selenium nanoparticles for enhanced antitumor efficacy in cervical carcinoma therapy.

Doxorubicin-loaded functionalized selenium nanoparticles for enhanced antitumor efficacy in cervical carcinoma therapy. Mater Sci Eng C Mater Biol Appl. 2020 Jan;106:110100 Authors: Xia Y, Xiao M, Zhao M, Xu T, Guo M, Wang C, Li Y, Zhu B, Liu H Abstract Development of novel tumor-targeted drug vehicles for cancer therapy is very important and has become one of major topics for designing nanoscale chemotherapeutics delivery systems. In the present study, selenium nanoparticles (SeNPs) was decorated with hyaluronic acid (HA) to prepare HA-SeNPs nanoparticles which were used to load doxorubicin (DOX) to fabricate tumor-targeted functionalized selenium nanoparticles HA-Se@DOX. In vitro and in vivo antitumor activities of HA-Se@DOX in human cervical carcinoma treatment were investigated. HA-Se@DOX showed selective cellular uptakes between cervical cancer HeLa cells and human umbilical vein endothelial cells (HUVEC). In vitro release result indicated that DOX was released from HA-SeNPs faster in acidic environment in comparison with normal physiological environment and 76.9% DOX was released in pH 5.4 during initial 30 h. HA-Se@DOX showed high activity to inhibit HeLa cell proliferation and triggered HeLa cell apoptosis via activating Bcl-2 signaling pathway. In vivo antitumor study showed that HA-Se@DOX inhibited tumor growth through suppressing cancer cells proliferation and inducing cancer cells apoptosis. Interestingly, HA-Se@DOX exhibited stronger ant...

Publication date: Available online 26 December 2019Source: Reports of Practical Oncology &RadiotherapyAuthor(s): Ramaiah Vinay Kumar, Suman BhaskerAbstractObesity has become epidemic both in developed and developing countries. Socio-economic (SE) development has resulted in increased prevalence of obesity across all social groups in developing countries that is contrary to the effects of a rising SE status on prevalence of obesity in the developed world. Obesity is not only associated with metabolic syndrome, cardiovascular disease, diabetes but is also a risk factor for cancer and is responsible for increased cancer m...

Conclusion: Our study demonstrates that ATMi can function like EGFRi in human tumor cells to inhibit tumor cell growth and sensitize the tumor cells to IR, suggesting that ATMi treatment as an alternative approach may exert anticancer effects on EGFRi-resistant tumor cells and facilitate radiotherapy.

DiscussionWith a look to the possibility of a 5-year survival in patients with a N+ status in level IV and V, the justification for a radical approach to the neck appears questionable. However, modified radical neck dissection appears to be a suitable for a high-risk oral cancer subgroup. A randomised controlled trial is needed to define guidelines for the neck dissection extent in c/pN + cases.

Targeting p53 activity has been suggested as an important strategy in cancer therapy. The purpose of this study was to describe a mechanism by which curcumin restores p53 levels in human cancer cell lines.HeLa,...

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...

Conclusion and Future Perspectives This review illustrates our current knowledge of USP7, including its source and characterization, structure, binding partners and substrates in various biological processes. Besides, how USP7 regulates various aspects of a cell under both normal and pathological states are elaborated in detail. As the processes of ubiquitination and deubiquitination are extremely dynamic and context-specific, a series of studies have linked USP7 to different cancers. The biology, particularly the immune oncology mechanisms, reveal that USP7 inhibitors would be useful drugs, thus it is vital to develop hi...
