HIF1A-dependent overexpression of MTFP1 promotes lung squamous cell carcinoma development by activating the glycolysis pathway.

Introduction: Mitochondrial fission process 1 () is an inner mitochondrial membrane (IMM) protein implicated in the development and progression of various tumors, particularly lung squamous cell carcinoma (LUSC). This study aims to provide a more theoretical basis for the treatment of LUSC.

Methods: Through bioinformatics analysis, was identified as a novel target gene of .

JHD205, A Novel Abemaciclib Derivative, Exerts Antitumor Effects on Breast Cancer by CDK4/6.

Background: Efficient targeted molecular therapeutics are needed for the treatment of triple-negative breast cancer (TNBC), a highly invasive and difficult-to-treat form of breast cancer associated with a poor prognosis.

Objectives: This study aims to evaluate the potential of selective CDK4/6 inhibitors as a therapeutic option for TNBC by impairing the cell cycle G1 phase through the inhibition of retinoblastoma protein (Rb) phosphorylation.

Methods: In this study, we synthesized a compound called JHD205, derived from the chemical structure of Abemaciclib, and examined its inhibitory effects on the malignant characteristics of TNBC cells.

USP14 regulates heme metabolism and ovarian cancer invasion through BACH1 deubiquitination and stabilization.

The deubiquitinating enzyme USP14 has been established as a crucial regulator in various diseases, including tumors, neurodegenerative diseases, and metabolic diseases, through its ability to stabilize its substrate proteins. Our group has utilized proteomic techniques to identify new potential substrate proteins for USP14, however, the underlying signaling pathways regulated by USP14 remain largely unknown. Here, we demonstrate the key role of USP14 in both heme metabolism and tumor invasion by stabilizing the protein BACH1.

WXJ-202, a novel Ribociclib derivative, exerts antitumor effects against breast cancer through CDK4/6.

Cyclin-dependent kinases 4 and 6 () are key regulatory proteins in the cell division and proliferative cycle in humans. They are overactive in many malignant tumors, particularly in triple-negative breast cancer (TNBC). Inhibition of targets can have anti-tumor effects.

Synthesis and biological evaluation of novel aromatic amide derivatives as potential BCR-ABL inhibitors.

BCR-ABL1 kinase is a key driver of the pathophysiology of chronic myeloid leukemia (CML). Current treatments need to broaden the chemical diversity of BCR-ABL1 kinase inhibitors to overcome drug resistance. We designed and synthesized a series of aromatic amide derivatives based on several generations of BCR-ABL1 kinase inhibitors.

The USP18-FBXO6 axis maintains the malignancy of ovarian cancer.

Ubiquitin-specific protease 18 (USP18) is a deubiquitinating enzyme that reverses the post-translational modification of target proteins by ISG15 or ubiquitin, and is involved in a variety of cellular processes, including signal transduction, viral infection, and cancer development. Although high levels of USP18 mRNA have been observed in several types of cancer, its pathological significance in ovarian cancer (OV) is still elusive. Here, by integrating the Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and Genotypic Tissue Expression (GTEx) databases, we found that USP18 was abnormally up-regulated in OV tissues, and the increased expression of USP18 was associated with poor prognosis.

SOX9-mediated UGT8 expression promotes glycolysis and maintains the malignancy of non-small cell lung cancer.

UDP-glycosyltransferases (UGTs) catalyze the covalent addition of sugars to small lipophilic chemicals and are associated with a wide range of diseases including cancer. The human genome contains 22 UGT genes which could be classified into four families: UGT1, UGT2, UGT3, and UGT8. The UGT8 family contains only one member which utilizes UDP galactose to galactosidate ceramide.
