Activity and Tissue Distribution of Antisense Oligonucleotide CT102 Encapsulated with Cytidinyl/Cationic Lipid against Hepatocellular Carcinoma
Insulin-like
growth factor 1 receptor (IGF1R), a cell surface receptor
with tyrosine kinase (TK) activity, has ligands abnormally expressed
in acute leukemia, multiple myeloma, breast, prostate, cervical, and
nonsmall cell lung cancers, Ewing’s sarcoma, and other malignant
tumors. IGF1R mediates the malignant proliferation, invasion, and
metastasis of tumor cells through a variety of signal transduction
pathways, and it is also involved in tumor angiogenesis and tumor
cell antiapoptosis. In this study, the neutral cytidinyl lipid DNCA
and cystine skeleton cationic lipid CLD from our laboratory could
be optimized to encapsulate antisense oligonucleotide (ASO) CT102
to form stable and uniform Mix/CT102 nanoparticles (NPs), which could
specifically target tumor cells that highly expressed IGF1R in vivo by intravenous administration. Compared with naked
CT102, the lipid complex could promote the uptake and late apoptosis
levels of HepG2 and Huh-7 cells, inhibiting cell proliferation efficiently.
We also found that Mix/CT102 could enter nucleus in about 2 h, effectively
downregulating the mRNA level of IGF1R. The in vivo efficacy experiment demonstrated that in the group that received
the optimal dose of Mix/CT102, tumor volume was reduced 8-fold compared
with the naked dose group. Meanwhile, in vivo distribution
studies showed that the nanoparticles had a predominant accumulation
capacity in liver tissue. These results indicated that clinicians
can expect the Mix/CT102 nanocomposite to be very effective in reducing
the dose and frequency of clinically administered CT102, thereby reducing
the side effects of ASOs
Data_Sheet_1_Probiotic lactic acid bacteria alleviate pediatric IBD and remodel gut microbiota by modulating macrophage polarization and suppressing epithelial apoptosis.docx
IntroductionThe incidence of pediatric inflammatory bowel disease (PIBD) continues to rise. It was reported that the probiotic lactic acid bacteria Pediococcus pentosaceus (P. pentosaceus) can interfere with intestinal immunity, but it is still unknown whether it can alleviate PIBD and the concrete mechanism of immune regulation is unclear.MethodsFor this study, 3-week-old juvenile mice were selected for modeling the development of PIBD. The mice treated with 2% DSS were randomly divided into two groups, which were given P. pentosaceus CECT8330 and equal amounts of solvent, respectively. The feces and intestinal tissue were collected for the mechanism exploration in vivo. THP-1 and NCM460 cells were used to investigate the effects of P. pentosaceus CECT8330 on macrophage polarization, epithelial cell apoptosis, and their crosstalk in vitro.ResultsP. pentosaceus CECT8330 obviously alleviated colitis symptoms of juvenile mice, including weight loss, colon length shortening, spleen swelling, and intestinal barrier function. Mechanistically, P. pentosaceus CECT8330 could inhibit intestinal epithelial apoptosis by suppressing the NF-κB signaling pathway. Meanwhile, it reprogramed macrophages from a pro-inflammatory M1 phenotype to an anti-inflammatory M2 phenotype, leading to a decreased secretion of IL-1β which contributes to the reduction in ROS production and epithelial apoptosis. Additionally, the 16S rRNA sequence analysis revealed that P. pentosaceus CECT8330 could recover the balance of gut microbiota, and a significantly increased content of Akkermansia muciniphila was particularly observed.ConclusionP. pentosaceus CECT8330 shifts macrophage polarization toward an anti-inflammatory M2 phenotype. The decreased production of IL-1β leads to a reduction in ROS, NF-κB activation, and apoptosis in the intestinal epithelium, all of which help to repair the intestinal barrier and adjust gut microbiota in juvenile colitis mice.</p
