Targeting CDK6 in cancer: State of the art and new insights.

Cyclin-dependent kinase 6 (CDK6) plays a vital role in regulating the progression of the cell cycle. More recently, CDK6 has also been shown to have a transcriptional role in tumor angiogenesis. Up-regulated CDK6 activity is associated with the development of several types of cancers.

Targeting Pim kinases for cancer treatment: opportunities and challenges.

Pim oncogenes are highly expressed in many types of hematological and solid cancers. Pim kinases regulate the network of signaling pathways that are critical for tumorigenesis and development, making Pim kinases the attractive drug targets. Currently, two approaches have been employed in designing Pim kinase inhibitors: ATP-mimetics and non-ATP mimetics; but all target the ATP-binding pocket and are ATP-competitive.

Spectrum of head and neck lesions diagnosed by fine-needle aspiration cytology in the pediatric population.

Fine-needle aspiration cytology (FNAC) of the head and neck region is well accepted as a diagnostic procedure in the adult population. FNAC in the pediatric population is gaining acceptance as clinicians add this technique to the diagnostic armamentarium. An experience with FNAC of the head and neck region in the pediatric population is described from 2 large inner-city hospitals.

Neuropeptide Y delays hippocampal kindling in the rat.

Chronic intrahippocampal infusion of the neurotrophin brain-derived neurotrophic factor (BDNF) has been shown to delay kindling epileptogenesis in the rat and several lines of evidence suggest that neuropeptide Y could mediate these inhibitory effects. Chronic infusion of BDNF leads to a sustained overexpression of neuropeptide Y in the hippocampus, which follows a time course similar to that of the suppressive effects of BDNF on kindling. In vivo, acute applications of neuropeptide Y or agonists of its receptors exert anticonvulsant properties, especially on seizures of hippocampal origin.
