Feedback control of PLK1 by Apolo1 ensures accurate chromosome segregation.

Stable transmission of genetic material during cell division requires accurate chromosome segregation. PLK1 dynamics at kinetochores control establishment of correct kinetochore-microtubule attachments and subsequent silencing of the spindle checkpoint. However, the regulatory mechanism responsible for PLK1 activity in prometaphase has not yet been affirmatively identified.

Cisplatin combined with laser‑activated nanotherapy as an adjuvant therapy for head and neck cancer.

Head and neck cancers (HNCs), in general, have a poor prognosis with a worldwide 5‑year survival rate of <50%. Numerous HNC patients with locoregionally advanced, difficult‑to‑treat, inoperable, recurrent and drug‑resistant tumors may require additional treatment options when the standard of care surgery, chemotherapy and radiation are not viable. The poor outcomes justify exploring strategies to increase the efficacy of lower doses of drugs, such as cisplatin, by combining these drugs with other treatment modalities and manipulating the dosing schedule.

A histological evaluation and in vivo assessment of intratumoral near infrared photothermal nanotherapy-induced tumor regression.

Purpose: Nanoparticle (NP)-enabled near infrared (NIR) photothermal therapy has realized limited success in in vivo studies as a potential localized cancer therapy. This is primarily due to a lack of successful methods that can prevent NP uptake by the reticuloendothelial system, especially the liver and kidney, and deliver sufficient quantities of intravenously injected NPs to the tumor site. Histological evaluation of photothermal therapy-induced tumor regression is also neglected in the current literature.

Nanodiamonds enhance therapeutic efficacy of doxorubicin in treating metastatic hormone-refractory prostate cancer.

Enhancing therapeutic efficacy is essential for successful treatment of chemoresistant cancers such as metastatic hormone-refractory prostate cancer (HRPC). To improve the efficacy of doxorubicin (DOX) for treating chemoresistant disease, the feasibility of using nanodiamond (ND) particles was investigated. Utilizing the pH responsive properties of ND, a novel protocol for complexing NDs and DOX was developed using a pH 8.

Nanodiamond-DGEA peptide conjugates for enhanced delivery of doxorubicin to prostate cancer.

The field of nanomedicine has emerged as an approach to enhance the specificity and efficacy of cancer treatments as stand-alone therapies and in combination with standard chemotherapeutic treatment regimens. The current standard of care for metastatic cancer, doxorubicin (DOX), is presented with challenges, namely toxicity due to a lack of specificity and targeted delivery. Nano-enabled targeted drug delivery systems can provide an avenue to overcome these issues.
