Abstract
Most existing hydrogels, even recently developed injectable hydrogels that undergo a reversible sol-gel phase transition in response to external stimuli, are designed to gel immediately before or after implantation/injection to prevent the free diffusion of materials and drugs; however, the property of immediate gelation leads to a very weak tumour-targeting ability, limiting their application in anticancer therapy. Therefore, the development of tumour-specific responsive hydrogels for anticancer therapy is imperative because tumour-specific responses improve their tumour-targeting efficacy, increase therapeutic effects, and decrease toxicity and side effects. In this review, we introduce the following three types of tumour-responsive hydrogels: (1) hydrogels that gel specifically at the tumour site; (2) hydrogels that decompose specifically at the tumour site; and (3) hydrogels that react specifically with tumours. For each type, their compositions, the mechanisms of tumour-specific responsiveness and their applications in anticancer treatment are comprehensively discussed.

Characterization of PDL1 enhanced siRNA/albumin liposome for effective therapeutic function in lung cancer. J Cancer Res Clin Oncol 2022:10.1007/s00432-022-04298-2. [PMID: 35997823 DOI: 10.1007/s00432-022-04298-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 08/15/2022] [Indexed: 10/15/2022]
Abstract
PURPOSE The applications of liposomes are limited due to poor structural stability and short drug circulation time. This study aims to build an albumin-based liposomal delivery system to provide strategies for tumor specificity, efficient gene delivery and effective release of albumin liposomes. METHODS In this study, siRNA loaded PDL1-targeted albumin liposome was constructed for the treatment of lung cancer and its function was evaluated. Physical parameters such as particle size, potential and infrared spectrum were detected and microscopic morphology was observed by electron microscopy to detect the binding and uptake capacity of albumin liposome with cells. The optimal preparation process and binding ratio of PDL1-targeted albumin liposome/siRNA complex were determined. RESULTS The constructed siRNA loaded PDL1-targeted albumin liposomes has low toxicity, high loading rate and tumor cell targeted gene therapy ability. Moreover, it increased T cell activation and down-regulated siRNA expression, effectively realizing the inhibition of lung cancer cells. CONCLUSION The results showed that the PDL1-targeted albumin liposome could be used as a high efficient delivery vector of siRNA, and was a high efficient and safe nano vector for tumor targeted gene therapy.
