Targeted delivery chemo-drugs to leukemia cells shows promise, but the diverse subtypes of leukemia make single-ligand nanomedicine often ineffective. Herein, a dual-aptamer decorated, reduction-responsive dimeric prodrug-based nanoparticle (NP), termed SXP-NPs, was developed using the two leukemia-specific aptamers Sgc8c and XQ-2d, a reduction-responsive podophyllotoxin (POD) dimeric prodrug, and DSPE-PEG2000. Because the receptors of XQ-2d (CD71) and Sgc8c (PTK7) are overexpressed in different subtypes of leukemia cells, SXP-NPs can broadly and selectively recognize these leukemia cells after intravenous administration, subsequently releasing POD in response to the intracellular high-reduction environment to kill the leukemia cells. In vitro experiments showed that these simple SXP-NPs can specifically bind to various leukemia cancer cells and kill them. In vivo experiments revealed that SXP-NPs can remarkably reduce spleen weight, decrease white blood cell counts, and extend overall survival in a preclinical leukemia animal model. The in vitro and in vivo validation demonstrated that SXP-NPs offer several advantages, including high drug-loading potential, broad-spectrum recognition of leukemia cells, reduced systemic toxicity, and enhanced therapeutic effects of the drug.

These limitations can be addressed by encapsulating the extracts in nanovesicles to enhance their release and bioavailability. This study aims to develop nanovesicles using Olea europaea leaf extract to exploit its potential anti-cancer properties. Soy lecithin was used to form liposomes for encapsulation of the olive leaf extract. In addition, ethanol and glycerol were added to form ethosomes and glycerosomes, respectively. The antiproliferative effect of both the free extract and the three formed nanovesicles was tested in MCF7 and MCF10A cell lines. To comprehend the mechanisms leading to reduced cell viability after exposure to olive leaf extract and its nanovesicles, levels of reactive oxygen species (ROS), mitochondrial membrane potential, and apoptotic stage were evaluated. The results suggest that both, the nanovesicles and the free extract, are antiproliferative agents against MCF7 tumour cells. However, when examining the impact of olive leaf extract and the formulated nanovesicles on MCF10A cells, no reduction in cell viability was observed. Our findings indicate that the anti-tumour effect of the extract and its nanovesicles may be due to increased oxidative stress, mediated by mitochondrial damage.

However, their efficacy against pancreatic cancer was insufficient in clinical trials, necessitating an imperative exploration of underlying mechanisms and new therapeutic strategies. In this study, we indicated that αTROP2-MMAE, an antibody-drug conjugate targeting TROP2, induced apoptosis through the caspase-9/PARP pathway and exerted potent antitumor effects against TROP2-positive pancreatic cancer. Simultaneously, RNA sequencing suggested significant changes in autophagy after αTROP2-MMAE treatment. The formation of autophagosomes and activation of autophagic flux were markedly induced through mechanisms associated with suppressing the activation of the Akt/mTOR pathway. The addition of pharmacological inhibitors of autophagy enhanced the cytotoxicity and apoptosis caused by αTROP2-MMAE, revealing the cytoprotective role of autophagy in TROP2-positive pancreatic cancer. In the subcutaneous xenograft model using BxPC3 cells, the combined administration of αTROP2-MMAE and an autophagy inhibitor elevated the tumor inhibition rate of αTROP2-MMAE from 71.6 % to 99.0 %, resulting in the eradication of tumors in half of the mice.
