Abstract Uridine-cytidine kinase 2 is an enzyme that is overexpressed in abnormal cell growth and its implication is considered a hallmark of malignancy. Due to the selective expression of UCK2 in malignancy cells, a selective inhibition of this important enzyme necessitates the discovery of its potential inhibitors for malignancy chemotherapy.

Extracts, flavokawain B, and alpinetin compound from your rhizome of was used in the study. The study exhibited that this expression of UCK2 mRNA were substantially reduced in treated HT-29 cells. In addition, downregulation in expression of 18S ribosomal RNA was also observed in all treated HT-29 cells. This was confirmed by fluorescence imaging to measure the level of expression of 18S ribosomal RNA in live cell images. The study suggests the possibility of MDM2 protein was downregulated and its suppression subsequently activates the expression of p53 during inhibition of UCK2 enzyme. The expression of p53 is directly linked to a blockage of cell cycle progression at G0/G1 phase and upregulates Bax, cytochrome studies have shown the ability of the bioactive compounds of flavokawain B and alpinetin to target UCK2 enzyme specifically, inducing cell cycle arrest and subsequently leading to cancer cell death, possibly through interfering the MDM2-p53 signalling pathway. These phenomena have proven that the bioactive compounds could be useful for future therapeutic use in colon cancer. Introduction Uridine-cytidine kinase 2 (UCK2) is an enzyme that catalyses the conversion of uridine and cytidine to their monophosphate form of uridine and cytidine in an alternative salvage pathway of pyrimidine biosynthesis [1]. A formation of 5′-triphosphate form of uridine and cytidine nucleosides are an essential requirement in gene replication. Overexpression of this enzyme have been implicated in several cancers and it is therefore considered a hallmark of cancer. The selective expression and non-immunogenicity of human UCK2 may, however represent a potential target for anticancer drug development [2]. Tumour suppressor protein, p53, prevents cancer development by eliminating cells with mutagenic alterations or potential for neoplastic transformation or blocking their cell cycle permanently or by transient DNA repair [3C5]. p53 is regulated by human double minute 2 (MDM2), an E3 ubiquitin ligase that targets and binds to p53 promoting ubiquitination and degradation of the protein [6,7]. Overexpression of MDM2 leads to inactivation of p53 tumour protein, thereby diminishing its tumour suppressor function [8]. Nonetheless, MDM2 is in turn regulated by ribosomal proteins (RPs) that binds and suppress the MDM2 E3 ubiquitin ligase activity resulting in the stabilization and activation of p53 [9]. These ribosomal proteins are found in stoichiometric amounts in the.Approximately 10 L of the extracted DNA was run on 1% gel electrophoresis and visualized under Gel Doc (Bio-rad, Hercules, CA, US).

These ribosomal protein are located in stoichiometric quantities in the ribosome, hence, these are portrayed in metabolically energetic cells going through proteins synthesis [9 abundantly,10]. The RPs are created via a complicated process composed of transcription, adjustment, digesting of ribosomal RNA (rRNA) and following production of the RPs [6]. Transcription of ribosomal DNA (rDNA) genes by RNA polymerase I generate the 47s rRNA precursor, as well as the digesting and adjustment of the transcript, generate the older 18S hence, 5.8S, and 28S rRNA. The rRNAs are constructed using the RPs to create 60S and 40S subunit from the older ribosome [11,12]. The subunit of 60S includes 28S, 5.8S and 5S rRNAs, whilst the 40S subunit contains 18S rRNA [13] mainly. In response towards the instability of ribosomal biogenesis like the depletion of nucleotides, many RPs are released through the nucleolus and stop MDM2 that goals p53 for degradation, this qualified prospects to p53 cell and induction cycle arrest [14].
