Journal of Integrative Plant Biology, EarlyView.Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Therapeutic Challenge with a CDK 4/6 Inhibitor Induces an RB-Dependent SMAC-Mediated Apoptotic Response in Non-Small Cell Lung Cancer. [PDF]
, 2018 Purpose: The retinoblastoma tumor suppressor (RB), a key regulator of cell-cycle progression and proliferation, is functionally suppressed in up to 50% of non-small cell lung cancer (NSCLC).

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation
Photochemistry and Photobiology, EarlyView.UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

The Role of the Ubiquitination–Proteasome Pathway in Breast Cancer: Use of Mouse Models for Analyzing Ubiquitination Processes [PDF]
, 2013 Turnover of several regulatory proteins results from targeted destruction via ubiquitination and subsequent degradation through the proteosome. The timely and irreversible degradation of critical regulators is essential for normal cellular function.

The Silent Link: Exploring the Impact of Periodontal Diseases on Head and Neck Carcinogenesis
Clinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.ABSTRACT Objectives Oral dysbiosis can accelerate the progression of head and neck squamous cell carcinoma (HNSCC) by fostering a pro‐inflammatory, immunosuppressive, and metabolically altered environment. This narrative review examines the relationships between periodontitis‐associated bacteria and HNSCC, focusing on their impact on oncogenic pathways,

The Cyclin-dependent Kinase Inhibitor p27Kip1 Is Involved in Thyroid Hormone-mediated Neuronal Differentiation [PDF]
Journal of Biological Chemistry, 1999 The thyroid hormone (triiodothyronine, T3) is essential for normal brain maturation. To determine the mechanisms by which T3 controls neuronal proliferation and differentiation, we have analyzed the effect of this hormone on the expression and activity of cell cycle-regulating molecules in neuroblastoma N2a-beta cells that overexpress the beta1 isoform

P27 Expression in Endothelin-1 Stimulated Mitogenesis [PDF]
, 2007 Bovine corneal endothelial cells (BCECs) have been shown in our lab to synthesize and secrete endothelin-1 (ET-1). The endothelin-1 binds ETA receptors, this elevates intracellular calcium, stimulate DNA replication and cell division.

Targeting EZH2 in Cancer: From Molecular Mechanisms to Clinical Translation
MedComm – Oncology, Volume 5, Issue 2, June 2026.The abnormal overexpression or gain‐of‐function mutations of EZH2 play a significant role in cancer occurrence and progression, highlighting the importance and potential of EZH2 as a cancer biomarker. Therefore, screening for effective and safe small‐molecule inhibitors, degraders, and natural compounds targeting EZH2 through preclinical cancer models ...

The Cyclin-dependent Kinase Inhibitors p57 and p27 Regulate Neuronal Migration in the Developing Mouse Neocortex [PDF]
Journal of Biological Chemistry, 2007 Neuronal precursors remain in the proliferative zone of the developing mammalian neocortex until after they have undergone neuronal differentiation and cell cycle arrest. The newborn neurons then migrate away from the proliferative zone and enter the cortical plate. The molecules that coordinate migration with neuronal differentiation have been unclear.
