Unlabelled: Objetive: To investigate the effects of PKF118-310 on cell cycle and proliferation of K562 cell lines and its mechanism.

Methods: After treatment of PKF118-310 with different concentration, the proliferation inhibition on K562 cell lines was detected by MTT, the existance of β-catenin and TCF-4 in the cells was observed by immunohistochemistry. The change of the cell cycle was detected by flow cytometry. The expressions of caspase-3, β-catenin, TCF and BCL-9 were detected by Western blot.

Results: PKF118-310 can inhibit the proliferation of K562 cell line by S phase blocking. The β-catenin and TCF in the cells were observed by immunohistochemistry. After treating this cell line with PKF118-310 of different concentrations for 72 h, the expression level of caspase-3 increased, the expression levels of β-catenin, TCF and BCL-9 significantly decreased.

Conclusion: PKF118-310 induces cycle arest of K562 cells at the S phase and inhibits the proliferation of these cells through decreasing β-catenin/TCF/BCL-9 thrascriptional activity.

NFKB1 as a key player in Tumor biology: from mechanisms to therapeutic implications.

Cell Biol Toxicol

January 2025

Department of Obstetrics and Gynecology, Shengjing Hospital of China Medical University, No. 36 Sanhao Street, Heping District, Shenyang , Liaoning Province, China.

NFKB1, a core transcription factor critical in various biological process (BP), is increasingly studied for its role in tumors. This research combines literature reviews, meta-analyses, and bioinformatics to systematically explore NFKB1's involvement in tumor initiation and progression. A unique focus is placed on the NFKB1-94 ATTG promoter polymorphism, highlighting its association with cancer risk across diverse genetic models and ethnic groups, alongside comprehensive analysis of pan-cancer expression patterns and drug sensitivity.

Knockdown of miR-182 changes the sensitivity of triple-negative breast cancer cells to cisplatin.

Nucleosides Nucleotides Nucleic Acids

Division of Hematology, Department of Internal Medicine, Medical Faculty, Tekirdağ Namık Kemal University, Tekirdağ, Turkey.

Breast cancer is the most common malignancy that affects women. MicroRNAs (miRNAs) play an essential role in cancer therapy and regulate many biological processes such as cisplatin resistance. The study's objective was to determine whether miR-182 dysregulation was the cause of cisplatin resistance in TNBC cell line MDA-MB-231.

Extensive homologous recombination safeguards oocyte genome integrity in mammals.

Nucleic Acids Res

January 2025

MOE Key Laboratory of Biosystems Homeostasis and Protection, College of Life Sciences, Zhejiang University, No.866 Yuhangtang Road, 310058, Hangzhou, China.

Meiosis in mammalian oocytes is interrupted by a prolonged arrest at the germinal vesicle stage, during which oocytes have to repair DNA lesions to ensure genome integrity or otherwise undergo apoptosis. The FIRRM/FLIP-FIGNL1 complex dissociates RAD51 from the joint DNA molecules in both homologous recombination (HR) and DNA replication. However, as a type of non-meiotic, non-replicative cells, whether this RAD51-dismantling mechanism regulates genome integrity in oocytes remains elusive.

The link of FOXO1 and FOXO4 transcription factors to development of the lens.

Dev Dyn

January 2025

Department of Pathology and Genomic Medicine, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.

Background: The FOXOs regulate the transcription of many genes, including ones directly linked to pathways required for lens development. However, this transcription factor family has rarely been studied in the context of development, including the development of the lens. FOXO expression, regulation, and function during lens development remained unexplored.
