| Abstract |
Neoadjuvant chemotherapy is commonly used to treat patients with locally advanced breast cancer and a common option for primary operable disease. However, systemic toxicity including cardiotoxicity and inefficient delivery are significant challenges form any chemotherapeutics. The development of targeted treatments that lower the risk of toxicity has, therefore, become an active area of research in the field of novel cancer therapeutics. Mesoporous silica nanoparticles (MSNs) have attracted significant attention as efficient drug delivery carriers, due to their high surface area and tailorable mesoporous structures. Eph receptors are the largest receptor tyrosine kinase family, which are divided into the A- and the B-type. Eph receptors play critical roles in embryonic development and human diseases including cancer. EphA2 is expressed in breast cancer cells and has roles in carcinogenesis, progression and prognosis of breast cancer. A homing peptide with the sequence YSAYPDSVPMMSK (YSA) that binds specifically to EphA2 was used to functionalize MSN. We focus on a novel EphA2-targeted delivery MSN system for breast cancer cells. We show that the EphA2 receptor is differentially expressed in breast cancer cells and highly expressed in the HER2-negative breast cancer cell line MCF7. Our results suggest that EphA2-targeted MSN for doxorubicin delivery (MSN-YSA-DOX) are more effective than MSN-DOX in treating breast cancer cell lines in vitro. Our preliminary observations suggest that the EphA2-targeted MSN delivery system may provide a strategy for enhancing delivery of therapeutic agents to breast cancer cells expressing EphA2, and potentially reduce toxicity while enhancing therapeutic efficacy. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 February 2018.
All research outputs
#19,221,261
of 23,815,455 outputs
Outputs from Cancer Chemotherapy and Pharmacology
#2,044
of 2,501 outputs
Outputs of similar age
#334,252
of 443,839 outputs
Outputs of similar age from Cancer Chemotherapy and Pharmacology
#20
of 27 outputs
Altmetric has tracked 23,815,455 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,501 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 11th percentile – i.e., 11% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 443,839 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
