AIM:To evaluate the killing effects of CDDP, 5-Fu and VCR on human hepaoma cell line (7721).METHODS:The median-effect principle was used.RESULTS:Killing effects of the individual drug were enhanced as the median concentration increased. Antagonism was produced when two drugs were used at a higher concentration (CI > 1), and synergism was achiened when CI < 1. Finally, the effect was influenced by both the ratios of drug concentration and the sequence of administration.CONCLUSION:The drug administration order and drug concentrations are significant factors that need to be considered in clinical practice.

Cancers still globally endanger millions of people yearly; the incidences/mortalities of colorectal cancers are particularly increasing. The natural nanoparticles (NPs) and marine biopolymers were anticipated to provide effectual safe significances for managing cancers. The transformation of curcumin to nano-curcumin (NCur) was conducted with gum Arabic.

Breast cancer was the most frequent cause of cancer death in females in 2022. Despite the development of personalized therapies, chemotherapy frequently remains the only available treatment method. However, the administration of classic antineoplastic drugs, like cisplatin (CDDP), often causes severe side effects and may lead to drug resistance making the therapy inefficient.

This study explores the design, synthesis, and evaluation of a novel series of isobenzofuran-based imidazo[2,1-b][1,3,4]thiadiazole derivatives, targeting their antimicrobial and anticancer properties. These compounds integrate the pharmacologically significant 1,3,4-thiadiazole and imidazole moieties, which are known for their potential in drug development, although imidazo[2,1-b][1,3,4]thiadiazole-based drugs are not yet available on the market. Therefore, the aim of this study is to develop novel derivatives that could serve as promising candidates for future therapeutic applications.

Cisplatin, a platinum-based chemotherapeutic agent, can be used to treat cervical cancer (CC), but cisplatin resistance is increased during the cisplatin treatment. Long non-coding RNA PGM5-AS1 reportedly participates in CC tumorigenesis; however, its role in CC patients with cisplatin resistance has not been revealed. The present aimed to examine the role of PGM5-AS1 in modulating cisplatin resistance in CC.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.
