Background: It has been reported that the tumor suppressor gene, PTEN, which is inactivated in many malignant tumors, plays an important role in apoptosis, cell cycle arrest, cell migration, and cell spread. For cancer gene therapy, one of the most important problems is low gene transfection efficiency.
Methods: In the present study, to take full advantage of adenovirus in gene expression, we prepared mannan-modified recombinant adenovirus using the PTEN gene (Man-Ad5-PTEN) and investigated the effect of Man-Ad5-PTEN combined with docetaxel (Man-Ad5-PTEN-docetaxel) on tumor growth in a murine model of hepatocellular carcinoma.
Results: Man-Ad5-PTEN effectively suppressed tumor growth and induced significant apoptosis of murine H22 hepatoma in vivo. Apoptosis levels in tumor-bearing mice treated with Man-Ad5-PTEN-docetaxel were significantly higher than those in tumor-bearing mice treated with naked Ad5-PTEN, Man-Ad5-PTEN, or docetaxel alone. Treatment with Man-Ad5-PTEN-docetaxel resulted in a significant inhibitory effect in this tumor model. Compared with the controls treated with phosphate-buffered solution, the tumor inhibition rate with naked Ad5-PTEN, docetaxel, Man-Ad5-PTEN, and Man-Ad5-PTEN-docetaxel was 48.69%, 49.98%, 75.88%, and 96.93%, respectively.
Conclusion: These results suggest that combined treatment with Man-Ad5-PTEN and other chemotherapeutic agents may be a potent adjuvant therapeutic approach for the treatment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) poses a serious threat to human life and health. Nowadays, liver-targeting drug delivery systems have been proven as a promising strategy in treating HCC. Angelica sinensis polysaccharide (ASP), a plant polysaccharide with good biocompatibility, has excellent aqueous solubility and intrinsic liver-targeted capability.

The photothermal conversion efficiency (PCE) stands as a pivotal determinant in the therapeutic efficacy of photothermal nanoagents (PTNAs) within the context of photothermal therapy (PTT). The dearth of universal strategies to greatly enhance PCE has markedly curtailed the practical deployment of PTNAs. Now this problem is addressed by proposing a universal approach founded on molecular rotors and J-aggregates, "highly efficient molecular motor matrix", to greatly elevate the PCE of traditional PTNAs.

Background: Chronic pain and cancer interact bidirectionally, with pain enhancing sensory peptides and potentially promoting tumor growth. Despite this, most chemotherapy-induced neuropathic pain (CIPN) studies overlook the contribution of cancer itself to neuropathy, focusing instead on chemotherapy-induced mechanisms. Animal models of chemotherapy-induced neuropathic pain (CINP) have been developed by injecting chemotherapeutic drugs such as paclitaxel into normal animals without cancer.

Hyaluronic acid derivatives have broad prospects in the in vivo targeted delivery of insoluble antitumor drugs. In this study, rhein-selenocystamine-hyaluronic acid (RSeHA) polymeric micelles (PMs) were designed and developed to load celastrol (Cela) to solve its poor water solubility, low bioavailability, and severe toxicity for breast cancer treatment. Cela-loaded RSeHA PMs (Cela/RSeHA PMs) with a particle size of 159.
