Breast Cancer Therapy In article number 2201971, Ruibing Wang and co-workers develop supramolecular peptide (based upon the host–guest interaction between cucurbit[7]uril Phe-Phe-Val-Leu-Lys) capped Au nanocages, to allow self-aggregation into micron-sized clusters inside spermine-overexpressed tumor cells, leading specific accumulation retention of nanocages in breast for synergistic photother...

BACKGROUND Melanoma patients vaccinated with tumor-associated antigens frequently develop measurable peptide-specific CD8+ T cell responses; however, such responses often do not confer clinical benefit. Understanding why vaccine-elicited responses are beneficial in some patients but not in others will be important to improve targeted cancer immunotherapies. METHODS AND FINDINGS We analyzed pe...

Although numerous carbohydrates play significant roles in mammalian cells, carbohydrate-based drug discovery has not been explored due to the technical difficulty of chemically synthesizing complex carbohydrate structures. Previously, we identified a series of carbohydrate mimetic peptides and found that a 7-mer peptide, designated I-peptide, inhibits hematogenous carbohydrate-dependent cancer ...

Malignant gliomas are associated with high mortality due to infiltrative growth, recurrence, and malignant progression. Even with the most efficient therapy combinations, median survival of the glioblastoma multiforme (grade 4) patients is less than 15 months. Therefore, new treatment approaches are urgently needed. We describe here identification of a novel homing peptide that recognizes tumor...

Introduction: Epidermal growth factor receptor (EGFR) has been shown to play a critical role in tumor cell growth and its overexpression has been observed in many epithelial tumors. In the field of cancer vaccine research, displaying the peptide mimotope on the surface of phage particles has shown promising results. Methods: In this study using m13-PVIII phage display system, two constructs we...

Antiangiogenic therapy can produce transient tumor regression in glioblastoma (GBM), but no prolongation in patient survival has been achieved. We have constructed a nanosystem targeted to tumor vasculature that incorporates three elements: (i) a tumor-homing peptide that specifically delivers its payload to the mitochondria of tumor endothelial cells and tumor cells, (ii) conjugation of this h...

A novel fusion peptide FSH33-53-IIKK was designed and expected to combine the follicle stimulating hormone receptor (FSHR) targeting and tumor toxicity. In vitro and in vivo study showed the anti-tumor activity of FSH33-53-IIKK was enhanced compared to that of IIKK only. FSH33-53-IIKK could inhibit the growth of tumor via apoptosis and autophagy pathways. In summary, combining the tumor marker-...

Introduction The membrane-associated form of heat shock protein 70 (Hsp70) represents a promising target for fluorescence-based intraoperative molecular imaging. Contrary to normal tissue cells, Hsp70 is selectively upregulated on the plasma membrane many tumor entities, including HNSCC.We investigated whether topical application fluorescence-labeled peptide tracer (TPP-IRDye800), that specific...

abstract background antibiotic resistance makes antimicrobial peptides (amps) agents an alternative for treatment of pathogenic diseases. they are isolated from various animals invertebrates, vertebrates and plants. the present study shows the electrophoretic pattern of protein and peptides from vicia faba seed and reports our first attempt to study the antibacterial activity of vicia faba seed...
