Article Abstract
Background: Clear cell renal cell carcinoma (ccRCC) is one of the most common tumors in the world and affects human health seriously. is a mitotic regulator which is essential to the metaphase-to-anaphase transition in cell cycle. Although plays a crucial role in the malignant progression of tumors, there are few reports on its role in ccRCC.
Methods: The transcriptional expression profile and clinical data of were downloaded from TCGA database and verified by qRT-PCR. Kaplan-Meier plotter was used to analyze the effect of on overall survival (OS), disease specific survival (DSS) and progression-free interval (PFI) of patients with ccRCC. Univariable and multivariable Cox regression analysis were used to determine the independent prognostic factors of ccRCC. The effects of on cell migration and invasion were detected by wound healing assay and transwell invasion assay, and CCK-8 assay, colony formation assay and cell cycle assay were used to detect the effect of on cell proliferation. In addition, the changes in cell cycle related proteins were detected by western blot.
Results: was highly expressed in human ccRCC and was positively correlated with pathologic stage, TNM stage and histologic grade. In addition, patients with high expression of had a poor prognosis. Univariable and multivariable Cox regression analysis identified that was an independent prognostic factor of ccRCC. Additionally, was also closely related to immune cell infiltration. Experiments identified that the knockdown of could significantly inhibit the proliferation, migration and invasion abilities of ccRCC. The expression of cyclin D1, CDK4 and CDK6 was also significantly reduced after knockdown.
Conclusions: plays a vital role in the development of ccRCC and may become a potential therapeutic target in the future.

Wings apart-like protein (WAPL) has emerged as a key player in maintaining genome integrity through its regulation of cohesin dynamics, which govern chromatin architecture and gene expression. WAPL mainly acts as a cohesin release factor and ensures proper chromosomal segregation during mitosis by promoting sister chromatid resolution. Owing to its prominent role in cell biology, WAPL dysregulation can cause genomic instability and disrupt chromosomal cohesion, leading to diseases such as cancer.

The Mediterranean Basin, a hotspot for tomato production, is one of the most vulnerable areas to climate change, where rising temperatures and increasing soil and water salinization represent major threats to agricultural sustainability. Thus, to understand the molecular mechanisms behind plant responses to this stress combination, an RNA-Seq analysis was conducted on roots and shoots of tomato plants exposed to salt (100 mM NaCl) and/or heat (42°C, 4 h each day) stress for 21 days. The analysis identified over 8000 differentially expressed genes (DEGs) under combined stress conditions, with 1716 DEGs in roots and 2665 in shoots being exclusively modulated in response to this specific stress condition.

Background: Preoperative embolization is hypothesized to reduce blood loss and operative time for meningioma resection, but the impact of preoperative embolization on long-term oncological outcomes and molecular features of meningiomas is incompletely understood. Here we investigate how preoperative embolization influences perioperative and long-term outcomes and molecular features of atypical WHO grade 2 meningiomas.
Methods: Patients who underwent resection of WHO grade 2 meningiomas from 1997 to 2021 were retrospectively identified from an institutional database.

Anaphase-promoting complex/cyclosome (APC/C) regulates the cell cycle by destruction of target proteins ubiquitination. However, understanding the control of APC/C has remained elusive. We identify APC2, the catalytic core subunit of APC/C, as a binding partner of active regulator of SIRT1 (AROS).

Introduction: The presence of severe hypoxic stress can drive tumor growth, angiogenesis, and metastatic characteristics via up-regulated hypoxia-inducible factor 1-alpha (HIF-1α). Hence, targeting HIF-1α is considered a promising strategy, as increased HIF-1α activity is a key factor in the aggressive phenotype of malignancies. In this study, we aimed to investigate the anti-cancer effects of several flavonoids, both single and in combination with PX-478, in breast cancer cell lines.
