Increasing evidence indicates the dysregulations and pivotal roles of lncRNAs in the development and progression of various cancers, including pancreatic cancer. Enhanced glycolytic flux and epithelial-to-mesenchymal transition (EMT) have been considered as important factors in driving the malignance of pancreatic cancer. Here, we sought to evaluate the biological role and involved mechanism of lncRNA CASC9 (CASC9) in pancreatic cancer. Our present study showed that CASC9 was upregulated in various pancreatic cancer cell lines. Loss- and gain-of function of CASC9 demonstrated its critical roles in promoting the glycolysis and EMT phenotypes of pancreatic cancer. Moreover, knockdown of CASC9 inhibited the tumorigenicity and metastasis . Additionally, our findings showed that hypoxia induced the expression of CASC9 and enhanced the binding of HIF-1α to its promoter. We also demonstrated that the positive feedback loop of CASC9 and the AKT/HIF-1α signaling cascade partially mediated this biological process. Altogether, our results suggest that CASC9 promotes the glycolysis and EMT of pancreatic cancer by a positive feedback loop with AKT/HIF-1α signaling, which is synergistically enhanced by the tumor hypoxic niche. Our study will provide potential therapeutic targets for treating pancreatic cancer.

KRAS is a proto-oncogene that is found to be mutated in 15% of all metastatic cancers with high prevalence in pancreatic, lung, and colorectal cancers. Additionally, patients harboring KRAS mutations respond poorly to standard cancer therapy. As a result, KRAS is seen as an attractive target for targeted anticancer therapy.

In order to make the drugs can cure the tumor precisely, this paper establishes the tumor immune dynamic model through the differential equation of tumor growth and analyzes the persistence of the tumor immune model. Research on dual anticancer drugs and commonly used coupling methods is carried out to complete the synthesis of polyethylene glycol dual anticancer drug couplers and the antitumor activity is analyzed to derive the degree of inhibition of polyethylene glycol dual anticancer drugs on tumor activity. From the four judging criteria, it was concluded that the polyethylene glycol bis-anti-cancer drug has a better curative effect on tumor cells.

The Kirsten rat sarcoma viral oncogene homolog (KRAS) protein plays a key pathogenic role in oncogenesis, cancer progression, and metastasis. Numerous studies have explored the role of metabolic alterations in KRAS-driven cancers, providing a scientific rationale for targeting metabolism in cancer treatment. The development of KRAS-specific inhibitors has also garnered considerable attention, partly due to the challenge of acquired treatment resistance.

The long-term impact of postoperative morbidity following laparoscopic liver resection for hepatocellular carcinoma is unclear. This study aimed to investigate whether the prognosis of hepatocellular carcinoma patients were affected by postoperative morbidity after laparoscopic liver resection. Hepatocellular carcinoma patients who underwent curative-intent laparoscopic liver resection were included.

Background: Transarterial chemoembolisation (TACE) is standard care for unresectable, non-metastatic hepatocellular carcinoma. We aimed to evaluate the addition of lenvatinib and pembrolizumab to TACE versus dual placebo plus TACE in patients with unresectable, non-metastatic hepatocellular carcinoma.
Methods: In this multicentre, randomised, double-blind, phase 3 study (LEAP-012), patients were recruited from 137 global sites in 33 countries or regions.
