Abstract
Antimicrobial peptides (AMPs) are becoming next-generation alternative antibacterial agents because of the rapid increase in resistance in bacteria against existing antibiotics, which can also be attributed to the formation of resilient biofilms. However, their widespread use is limited because of their poor absorption, higher dosage requirements, and delayed onset of the bioactivity to elicit a desired response. Here we developed a short AMP that specifically targeted Fusobacterium nucleatum. We conjugated 23R to a statherin-derived peptide (SDP) through rational design; this conjugate binds to FomA, a major porin protein of F. nucleatum. The SDP-tagged 23R exhibited rapid and highly specific bactericidal efficacy against F. nucleatum. Further, IC50 values were in the nanomolar range, and they were 100-fold lower than those obtained with unconjugated 23R. In a human gut microbiota model, 0.1 nM SDP-23R achieved 99% clearance of F. nucleatum ATCC 25586 without markedly altering resident microbiota. Here we demonstrated that binding-peptide-coupled AMPs show increased killing efficacy and specificity for the target pathogen without affecting the resident microbiota.

Abstract
In recent years, substantial therapeutic efficacy of antibody-drug conjugates (ADCs) has been validated through approvals of 16 ADCs for the treatment of malignant tumors. However, realization of the maximum clinical use of ADCs requires surmounting extant challenges, mainly the limitations in tumor penetration capabilities when targeting solid tumors. To resolve the hurdle of suboptimal tumor penetration, miniaturized antibody fragments with engineered formats have been harnessed for ADC assembly. By virtue of their reduced molecular sizes, antibody fragment-drug conjugates hold considerable promise for efficacious delivery of cytotoxic agents, thus conferring superior therapeutic outcomes. This review will focus on current advancements in novel ADC development utilizing smaller antibody formats from ~6 to 80 kDa, with particular emphasis on single-domain antibodies, which have been widely applied in novel ADC design. Additionally, strategies to optimize clinical translation are discussed, including half-life extension, acceleration of internalization, and reduction of immunogenic potential.

Abstract
Colorectal cancer (CRC) is a common malignant tumor, and traditional treatments include surgical resection and radiotherapy. However, local recurrence, distal metastasis, and intestinal obstruction are significant problems. Oral nano-formulation is a promising treatment strategy for CRC. This study introduces physiological and environmental factors, the main challenges of CRC treatment, and the need for a novel oral colon-targeted drug delivery system (OCDDS). This study reviews the research progress of controlled-release, responsive, magnetic, targeted, and other oral nano-formulations in the direction of CRC treatment, in addition to the advantages of oral colon-targeted nano-formulations and concerns about the oral delivery of related therapeutic agents to inspire related research.

Abstract
Phage display was first described by George P. Smith when it was shown that virus particles were capable of presenting foreign proteins on their surface. The technology has paved the way for the evolution of various biomolecules presentation and diverse selection strategies. This unique feature has been applied as a versatile platform for numerous applications in drug discovery, protein engineering, diagnostics, and vaccine development. Over the decades, the limits of biomolecules displayed on phage particles have expanded from peptides to proteomes and even alternative scaffolds. This has allowed phage display to be viewed as a versatile display platform to accommodate various biomolecules ranging from small peptides to larger proteomes which has significantly impacted advancements in the biomedical industry. This review will explore the vast array of biomolecules that have been successfully employed in phage display technology in biomedical research.

[PMID: 38151631 DOI: 10.1007/s12032-023-02273-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 11/27/2023] [Indexed: 12/29/2023]
Abstract
The epithelial cell adhesion molecule (EpCAM) is a critical glycoprotein involved in cell cycle progression, proliferation, differentiation, migration, and immune evasion. Its role as a target for bispecific antibodies has shown promise in annihilating cancer cells. EpCAM's potential as a biomarker for tumor-initiating cells, characterized by self-renewal and tumorigenic capabilities, underscores its value in early cancer detection, immunotherapy, and targeted drug delivery. While EpCAM monotherapies have been met with limited success, bispecific antibodies targeting both EpCAM and other proteins have exhibited encouraging results in colorectal cancer (CRC) research. The integration of EpCAM-directed nanotechnology in drug delivery systems has emerged as a pivotal innovation in CRC treatment. Moreover, developing chimeric antigen receptor (CAR) T-cell and CAR natural killer (NK) cell therapies opens promising therapeutic avenues for EpCAM-positive CRC patients. Although preliminary, this review sets the stage for future advances. Additionally, this study advances our understanding of the role of non-coding RNAs in CRC, which may be pivotal in gene regulation and could provide insights into the molecular underpinning. The findings suggest that lncRNA, miRNA, and circRNA could serve as novel therapeutic targets or biomarkers, further enriching the landscape of CRC diagnostics and therapeutics.

Abstract
The early and non-invasive diagnosis of tumor diseases has been widely investigated by the scientific community focusing on the development of sensors/biomarkers that act as a way of recognizing the adhesion of circulating tumor cells (CTCs). As a challenge in this area, strategies for CTCs capture and enrichment currently require improvements in the sensors/biomarker's selectivity. This can be achieved by understanding the biological recognition factors for different cancer cell lines and also by understanding the interaction between surface parameters and the affinity between macromolecules and the cell surface. To overcome some of these concerns, electrochemical sensors have been used as precise, fast-response, and low-cost transduction platforms for application in cytosensors. Additionally, distinct materials, geometries, and technologies have been investigated to improve the sensitivity and specificity properties of the support electrode that will transform biochemical events into electrical signals. This review identifies novel approaches regarding the application of different specific biomarkers (CD44, Integrins, and EpCAm) for capturing CTCs. These biomarkers can be applied in electrochemical biosensors as a cytodetection strategy for diagnosis of cancerous diseases.
