Aptamer-conjugated nano-liposome for immunogenic chemotherapy with reversal of immunosuppression.

J Control Release 2022 Jun 24. Epub 2022 Jun 24.

Department of Bioscience and Biotechnology, Konkuk University, Seoul 05029, Republic of Korea. Electronic address:

Cancer cells have various immune evasion mechanisms that resist the immune cells by reprogramming the tumor microenvironment (TME), such as programmed death-ligand 1 (PD-L1) and indoleamine 2,3-dioxygenase-1 (IDO1) overexpression. One of the approaches to restore antitumor immune response by T-cells is through induction of immunogenic cell death (ICD). Thus, drug carrier containing IDO1 siRNA and ICD inducer would be effective anticancer regimen to modulate the immunosuppressive TME by reversing the IDO1-mediated immunosuppression in a synergistic combination with ICD induction.

Intraoperative Ultrasound-Guided Excision of Non-Palpable and Palpable Breast Cancer: Systematic Review and Meta-Analysis.

Ultraschall Med 2022 Jun 27. Epub 2022 Jun 27.

Department for Women's Health, University of Tübingen, Tübingen, Germany.

Wire-guided localization (WGL) is the most frequently used localization technique in non-palpable breast cancer (BC). However, low negative margin rates, patient discomfort, and the possibility of wire dislocation have been discussed as potential disadvantages, and re-operation due to positive margins may increase relapse risk. Intraoperative ultrasound (IOUS)-guided excision allows direct visualization of the lesion and the resection volume and reduces positive margins in palpable and non-palpable tumors. Read More

Walking Dead Tumor Cells for Targeted Drug Delivery Against Lung Metastasis of Triple Negative Breast Cancer.

Adv Mater 2022 Jun 27:e2205462. Epub 2022 Jun 27.

State Key Laboratory of Drug Research & Center of Pharmaceutics, Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai, 201203, China.

Lung metastasis is challenging in patients with triple-negative breast cancer (TNBC). Surgery is always not available due to the dissemination of metastatic foci and most of drugs are powerless because of poor retention at metastatic sites. TNBC cells generate inflamed microenvironment and overexpress adhesive molecules to promote the invasion and colonization. Read More

Tools for Contralateral Prophylactic Mastectomy Decision Making.

J Clin Oncol 2022 Jun 27:JCO2102782. Epub 2022 Jun 27.

Division of Surgical Oncology and Endocrine Surgery, University of Texas Health, San Antonio, TX.

Purpose: Women with unilateral breast cancer are increasingly opting for the removal of not only the involved breast, but also for the removal of the opposite uninvolved breast (contralateral prophylactic mastectomy [CPM]), although the risk of contralateral breast cancer (CBC) has decreased in recent years. Models to predict the absolute risk of CBC can help a woman decide whether to undergo CPM. Our objective is to illustrate that a better decision can be made if the patient and doctor also have estimates of the absolute risks of regional and distant recurrences and mortality from non-breast cancer causes.

MY11 exerts antitumor effects through activation of the NF-κB/PUMA signaling pathway in breast cancer.

Invest New Drugs 2022 Jun 27. Epub 2022 Jun 27.

Institute of Chinese Traditional Surgery, Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai, 200032, China.

Breast cancer is the most common malignancy in women worldwide, and the discovery of new effective breast cancer therapies with lower toxicity is still needed. We screened a series of chalcone derivatives and found that MY11 ((E)-1-(2-hydroxy-4,6-dimethoxyphenyl)-3-(4-piperazinylphenyl) prop-2-en-1-one) had the strongest anti-breast cancer activity. MY11 inhibited the growth of MDA-MB-231 and MCF-7 breast cancer cells by arresting the cell cycle and promoting apoptosis, through regulation of the cell cycle and apoptosis-related proteins.

Small-Molecule Gankyrin Inhibition as a Therapeutic Strategy for Breast and Lung Cancer.

J Med Chem 2022 Jun 27. Epub 2022 Jun 27.

Department of Pharmaceutical Sciences, College of Pharmacy and Health Sciences, St. John's University, Queens, New York 11439, United States.

Gankyrin is an oncoprotein responsible for the development of numerous cancer types. It regulates the expression levels of multiple tumor suppressor proteins (TSPs) in liver cancer; however, gankyrin's regulation of these TSPs in breast and lung cancers has not been thoroughly investigated. Additionally, no small-molecule gankyrin inhibitor has been developed which demonstrates potent anti-proliferative activity against gankyrin overexpressing breast and lung cancers. Read More
