Therefore, CDKs are desirable targets for cancer treatment. Since abnormal expression of CDK4/6 is the etiology of glioblastoma, it is imperative to investigate the mechanism underlying CDK4/6 selectivity for inhibitors compared to CDK1/2, another member of the family.

Reactive oxygen species (ROS) play a dual role in the pathophysiology of acute myeloid leukemia (AML), functioning as both signaling molecules and agents of cellular damage. This review offers an in-depth analysis of ROS production in AML, highlighting their impact on essential cellular pathways that govern cell survival, proliferation, and apoptosis. It explores both natural and synthetic pharmacological agents that modulate ROS generation and enhance oxidative stress, assessing their therapeutic potential and the challenges they present in clinical practice.
View Article and Find Full Text PDFFerroptosis denotes a distinct form of controlled cell death marked by substantial iron buildup and significant lipid peroxidation, playing a crucial role in several disease processes linked to cell death. Given the liver's essential functions in iron and lipid metabolism and its vulnerability to oxidative damage, more research has investigated the correlation between ferroptosis and numerous hepatic diseases, including metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD). NAFLD has arisen as a worldwide public health concern due to elevated morbidity and high death rates.

Long non-coding RNAs (lncRNAs), defined as RNA transcripts longer than 200 nucleotides, have emerged as pivotal regulators in the initiation and progression of various malignancies. In oncology, programmed cell death (PCD) serves as the primary mechanism for tumor cell elimination, comprising processes such as apoptosis, pyroptosis, autophagy, and ferroptosis.

Oropharyngeal cancer, a subset of head and neck cancer, is increasingly recognized as a unique clinical entity primarily influenced by high-risk human papillomavirus (HPV) infections, particularly HPV-16. This review delves into the viral life cycle of HPV-16 and its interactions with host cells, with a specific focus on the crucial roles played by the viral oncoproteins E6 and E7. These oncoproteins drive cellular proliferation by targeting critical tumor suppressor proteins like p53 and Rb, resulting in uncontrolled cell growth and genomic instability.

The extracellular matrixes (ECM), as well as the microenvironmental signals, play an essential role in osteogenesis by regulating intercellular pathways. Recently, it has been demonstrated that a newly identified RNA, circular RNA, contributes to the osteogenesis process. Circular RNA (circRNA), the most recently identified RNA, is involved in the regulation of gene expression at transcription to translation levels.
