The Vestigial-Like Family Member 4 (VGLL4) functions as a native inhibitor of cell proliferation and tumor growth through multiple signaling pathways. We first discovered that VGLL4 causes G2/M phase arrest in hepatocellular carcinoma (HCC) cells. Then, we designed a novel survivin-regulated oncolytic adenovirus Ad-sp-VGLL4 carrying the VGLL4 gene. Ad-sp-VGLL4 exerted high HCC-targeting-selectivity but is less harmful to normal cells. This adenovirus construction enhanced antitumor activity due to G2/M phase arrest and enhanced apoptosis. It's also indicated that Ad-sp-VGLL4 could suppress the growth of transplanted tumor of HCC in vivo experiment. Taken together, our results suggest that Ad-sp-VGLL4 possesses strong antitumor capacity and has great potential use for HCC therapy.

Clear cell renal cell carcinoma is a prevalent urological malignancy, imposing substantial burdens on both patients and society. In our study, we used bioinformatics methods to select four putative target genes associated with EMT and prognosis and developed a nomogram model which could accurately predicting 5-year patient survival rates. We further analyzed proteome and single-cell data and selected PLCG2 and TMEM38A for the following experiments.

Corynoline (COR) is an isoquinoline alkaloid derived from the traditional Chinese medicine Corydalis bungeana Turcz, known for its analgesic, antibacterial, neuroprotective, and osteoporosis-alleviating properties. However, its potential molecular effects against osteosarcoma (OS) remain unclear, warranting further investigation. This study demonstrated that COR inhibits OS cell proliferation and promotes apoptosis in a dose-dependent manner.

: In the quest for sustainable and biocompatible materials, silk fibroin (SF), derived from natural silk, has emerged as a promising candidate for nanoparticle production. This study aimed to fabricate silk fibroin particles (SFPs) using a novel swirl mixer previously presented by our group, evaluating their characteristics and suitability for drug delivery applications, including magnetic nanoparticles and dual-drug encapsulation with curcumin (CUR) and 5-fluorouracil (5-FU). : SFPs were fabricated via microfluidics-assisted desolvation using a swirl mixer, ensuring precise mixing kinetics.

Although curcumin is a well-known natural polyphenol with many biological activities, its clinical application has been limited by low aqueous solubility and stability. Therefore, curcumin derivatives have been proposed to overcome these limitations and increase anticancer activity. This study tested curcumin derivatives with modified feruloyl moieties ( and ) and the β-diketo moiety () to better understand their anticancer mechanism against human bladder cancer cells.

Colorectal cancer is one of the most common cancers worldwide and has a high mortality rate. In this study, we investigated the cytotoxic, proapoptotic, and anti-invasive effects of the synthetic indole phytoalexin MB-653. The antiproliferative effect was determined using an MTT assay, showing IC values of 5.
