West African Medicinal Plant Substances and Molecules Activities Against Viral Hepatitis B and Hepatocellular Carcinoma
Zongo PFI, Bayala B and Simpore J
Chronic hepatitis B virus (HBV) infection remains a major global public health problem with devastating consequences, such as hepatocellular carcinoma. Currently, approved treatments are limited to interferon and nucleoside/nucleotide analogues for chronic hepatitis B and chemotherapy, radiotherapy, and surgery for cancer. Both treatments have their limitations, making complete cure an elusive goal. Therefore, the identification of new therapeutic targets using medicinal plants and the development of new antiviral and anticancer strategies are of utmost importance.

Zheng B, Zhang W, Xie S, Han Y, Liu G, Liu Y, Gao M, Wang S and Liu Q
Selinexor treats lung cancer, particularly non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). This review summarizes the prevalence and types of lung cancer and emphasizes the challenges associated with current treatments like resistance and limited effectiveness. Selinexor is a selective inhibitor of nuclear export (SINE) that has emerged as a potential therapy that targets the nuclear export of tumor suppressor proteins. The mechanisms of selinexor, its potential in combination therapies, and challenges like side effects and drug resistance are explained in this review. Key findings highlight the effectiveness of selinexor in preclinical studies, particularly against KRAS-mutant NSCLC and in combination with chemotherapy for SCLC. The review concludes with a discussion of future directions and underscores the potential of selinexor to improve the treatment strategies for lung cancer.

Phosphofructokinase-1 in Cancer: A Promising Target for Diagnosis and Therapy
Ishaq AR, Younis T, Lin S, Usman M, Wang T and Chen ZS
Tumor cells have distorted enzymatic houses, which change the metabolic state from oxidative phosphorylation to glycolysis with high lactate levels in a hypoxic environment. Redrafting the metabolic profile is an emerging hallmark of cancer. Glycolytic enzyme amplification occurs in about 70% of all malignancies. Current studies have found that PFK-1 overexpression is linked to cell migration, proliferation, and Overall Survival (OS) rate in various human cancer cell lines. This review intended to uncover the bona fide therapeutic target for cancer therapy and elucidate the role of PFK-1 in cancer. Furthermore, this review has outlined the listed pharmacological and genetic inhibitors of PFK-1. Following this review, future studies on PFK-1 should emphasize the molecular pathways implicated in PFK-1 overexpression in cancer development. The terms "PFK-1", "PFKP-1", "PFKL-1", "PFKM-1", "PFKM-1 and cancer", "PFKP-1 and cancer", "PFKL-1 and cancer", and "inhibitors of PFK-1" were used to retrieve the information from a variety of databases, including PubMed, Scopus, Google Scholar, and ScienceDirect. In a variety of malignancies, inhibiting the expression of PFK-1 isoforms has been reported to be the most effective therapeutic method. Overexpression of PFK-1 isoforms induces the Warburg effect, cell proliferation, and carcinogenesis by downregulating apoptotic proteins, such as active caspase-3, caspase-9, and caspase-8. YY1, synoviolin, Sh-RNA-507, SNAI, miR-520a/b/e, miR-128, and β-miR-6517 are some of the putative genetic inhibitors against PFK-1 that have been used to manage the development of malignancies. Pharmacological inhibitors, such as penfluridol, synoviolin/HRD1, quercetin, ginsenoside 20(S)-Rg3, triptolide, worenine, acetylsalicylic acid, and salicylic acid, can regulate the advancement of malignancies by inhibiting PFK-1. Thus, PFK-1 is a promising molecular biomarker for cancer treatment. A prospective investigation can validate the unbiased approaches for discovering brandnew PFK-1 inhibitors for cancer treatment.

Ruthenium Complex Suppresses Proliferation of Residual Hepatocellular Carcinoma after Incomplete Radiofrequency Ablation Therapy
Yu ZJ, Guo SW, Wang BS, Ouyang S, Zhang XH, Zhao ZZ and Wang JQ
Radiofrequency ablation (RFA) is an effective therapy for hepatocellular carcinoma (HCC). However, incomplete radiofrequency ablation (IRFA) can promote the progression of residual cancer cells, which is a serious problem in the clinical application of RFA. Therefore, it is of great significance to explore the mechanism and countermeasures of the progression of residual tumors after IRFA. Our previous study confirmed that IRFA can activate the hypoxia/ autophagy pathway of residual tumors in mice and then induce the proliferation of residual tumor cells. Additionally, we found a metal ruthenium complex [Ru(bpy)2(ipad)](ClO4)2 (Ru, where bpy = 2,2'-bipyridine and ipad = 2-(anthracene-9,10-dione-2-yl)imidazo[4,5-f][1,10]phenanthroline) can effectively inhibit hypoxia-inducible factor (HIF-1α) and has good anti-tumor effect in a hypoxic environment; however, whether Ru could suppress the proliferation of residual tumor cells after IRFA is unknown.

Adhesin Component Member STAG2 Enhances Cisplatin Tolerance in Colorectal Cancer Cells through the Epithelial-Mesenchymal Transition Pathway
Zhou P, Ye M, Chen C and Zhang R
Platinum-based compounds are commonly used as an initial treatment for colorectal cancer (CRC). However, the development of drug resistance in patients with CRC necessitates the administration of high drug concentrations during clinical treatment, thereby augmenting the toxicity of platinum-based compounds and increasing the mortality rate. STAG2 is a significantly associated drug-resistance gene in many cancers, but it has not been studied in colorectal cancer. Therefore, the present study aimed to investigate the role and drug sensitivity of the cisplatin-resistant gene STAG2.
