Targeting delivery of partial VAR2CSA peptide guided N-2-Hydroxypropyl trimethyl ammonium chloride chitosan nanoparticles for multiple cancer types

Publication date: January 2020Source: Materials Science and Engineering: C, Volume 106Author(s): Kai Zhao, Guogang Cheng, Baozhen Zhang, Dan Li, Jinyu Han, Jie Chen, Baobei Wang, Mengxia Li, Tianxia Xiao, Aiwen Le, Beini Sun, Zheng Jin, Jian Zhang, Xiujun FanAbstractTo developing a multiple cancer types targeting drug delivery carrier system, a 28 amino acids from the VAR2CSA was synthesized as the placental CSA-binding peptide (plCSA-BP). Its specific binding ability to cancer cells was tested on cancer tissue array, and the results showed that plCSA-BP could bind to multiple cancer types. Then, the plCSA-BP was used as a guiding peptide to coat nanoparticles synthesized from N-2-HACC (CSA/HACC-NPs) which were loaded with prodigiosin (CSA/HACC-PNPs) or indocyanine green (CSA/HACC-INPs). The cancer cells specific targeting and efficacy of the CSA/HACC-PNPs were tested by different cancer cells in vitro and various cancer xenograft model in vivo. A scramble peptide (SCR) was used as control and synthesized SCR/HACC-PNPs and SCR/HACC-INPs. The results showed that the CSA/HACC-INPs could specifically uptake by JEG-3, PC3 and A594 cells, and the CSA/HACC-PNPs exhibited better anti-cancer activity and lower toxic effect in subcutaneous choriocarcinoma and prostatic tumor models compared with the free prodigiosin, HACC-PNPs and SCR/HACC-PNPs. So, the CSA/HACC-NPs could be used as a specific delivery carrier for multiple cancer types, and provided an alternate treatment option of va...

Louwen Yuan Tumor progression and pregnancy have several features in common. Tumor cells and placental trophoblasts share many signaling pathways involved in migration and invasion. Preeclampsia, associated with impaired differentiation and migration of trophoblastic cells, is an unpredictable and unpreventable disease leading to maternal and perinatal mortality and morbidity. Like in tumor cells, most pathways, in which p21 is involved, are deregulated in trophoblasts of preeclamptic placentas. The aim of the present study was to enlighten p21’s role in tumorigenic choriocarcinoma and trophoblastic cell l...

Abstract Nongestational choriocarcinoma is rare, especially in postmenopausal women. It may be derived from the transformation of germ cells or dedifferentiation of other tumor tissue cells. It is usually found in the ovaries but rarely in the uterus. Pure nongestational uterine choriocarcinoma in postmenopausal women is exceptional. Thirty-four cases of choriocarcinoma have been found during the past 25 y at the Tianjin Medical University General Hospital. We retrospectively reviewed the medical records of these 34 cases and found only two cases of nongestational uterine choriocarcinoma, both of which were postme...

In this study, we generated TCam-2 cells double-deficient for SOX2 and FOXA2 using the CRISPR/Cas9 technique and xenografted those cells into the flank of nude mice. Upon loss of SOX2 and FOXA2, TCam-2 maintained a seminoma cell fate for at least twelve weeks, demonstrating that both factors are key players in the reprogramming to an EC-like cell fate. Therefore, our study adds an important piece to the puzzle of GCT development and plasticity, providing interesting insights in what can be expected in a patient, when GCT cells are confronted with different microenvironments.

This study demonstrates that propofol suppresses cell proliferation and metastasis through up-regulation of miR-495 and down-regulation of Twist1 in JEG3 cells. Highlights Propofol inhibits proliferation and metastasis in JEG-3 cells; miR-495 is up-regulated by propofol in JEG-3 cells; miR-495 suppression blocks the effect of propofol in JEG-3 cells; Propofol decreases Twist1 expression through up-regulating miR-495; Propofol inhibits TGF-β signalling via regulation of Twist1.

In this study, it was shown that the main factor determining the nature of the biodistribution of conjugates is their lipophilicity. Conjugates of siRNA with lower lipophilicity; i.e., derivatives of retinoic acid, lithocholic acid, and docosahexanoic acid with greater efficiency than cholesterol conjugates accumulated in the kidneys, bladder, and lungs of the mouse after subcutaneous injection (Biscans et al., 2018). This fact is consistent with previous data that showed that more lipophilic conjugates bind more efficiently to serum components, and thus are not excreted by the kidneys (Wolfrum et al., 2007; Osborn et al.,...
