OBJECTIVE: To determine the methylation profile of the selected CTAs in our colorectal cancer patients.
METHODS: A total of 54 pairs of colorectal cancer samples were subjected to DNA methylation profiling using the Infinium Human Methylation 450K bead chip.
RESULTS: We found that most of the CTAs were hypomethylated, and CCNA1 and TMEM108 genes were among the few CTAs that were hypermethylated.
CONCLUSION: Overall, our brief report has managed to show the overall methylation profile in over the 200 CTAs in colorectal cancer and this could be used for further refining any immunotherapy targets.
METHODS: COVID-19 samples that tested positive by reverse transcription polymerase chain reaction and with cycle threshold values <30 were obtained throughout Malaysia. Sequencing of SARS-CoV-2 complete genomes was performed using Illumina, Oxford Nanopore, or Ion Torrent platforms. A total of 6163 SARS-CoV-2 complete genome sequences were generated over the surveillance period. All sequences were submitted to the Global Initiative on Sharing All Influenza Data database.
RESULTS: From June 2021 to January 2022, Malaysia experienced the fourth wave of COVID-19 dominated by the Delta variant of concern, including the original B.1.617.2 lineage and descendant AY lineages. The B.1.617.2 lineage was identified as the early dominant circulating strain throughout the country but over time, was displaced by AY.59 and AY.79 lineages in Peninsular (west) Malaysia, and the AY.23 lineage in east Malaysia. In December 2021, pilgrims returning from Saudi Arabia facilitated the introduction and spread of the BA.1 lineage (Omicron variant of concern) in the country.
CONCLUSION: The changing trends of circulating SARS-CoV-2 lineages were identified, with differences observed between west and east Malaysia. This initiative highlighted the importance of leveraging research expertise in the country to facilitate pandemic response and preparedness.
METHODS: This was a cross-sectional study conducted among undergraduate pharmacy students in a public university in Malaysia using a validated and pre-tested self-administered questionnaire. The study was conducted in November and December 2019. The data was analysed using descriptive and inferential statistical tests.
RESULTS: Of the 318 female undergraduate students invited, 219 completed the questionnaire (response rate: 68.9%) with 52% aged between 21 and 23 years. The prevalence of dysmenorrhea was 72.1%, and the prevalence of ever-use and current use of CATs was 70.3 and 54.4%, respectively. Bed rest (71.5%), hot compress/heating pad (47.5%) and massage (43.0%) were the most common CATs used by the respondents. The most common reasons for using CAT were to reduce the need for analgesics (61.4%), efficacy (37.3%) and recommendation by others (32.9%). About 23 and 9% of the respondents believed that CATs were equally "effective" and "more effective" than analgesics, respectively. Reducing the need for analgesics (AOR: 4.066, 95% CI: 2.136-7.739) and those who agreed that CATs are effective (AOR: 2.701, 95% CI: 1.337-5.457) were independently associated with the current use CATs for the treatment of menstrual pain.
CONCLUSION: The prevalence of ever-use and current use of CATs is high among female undergraduate pharmacy students. Bed rest and heat applications are the most common CATs used. Reducing the need for analgesics and efficacy are the factors associated with the current use of CATs. Students should be educated about the safe and effective use of CATs to reduce adverse effects and improve their quality of life.
METHOD: Several methods were employed to assess the function of LOC285629 such as gene silencing, qPCR, proliferation assay, BrdU assay, transwell migration assay, ELISA and protein profiler.
RESULTS: Via in silico analyses, we identified significant downregulation of LOC285629, a novel lncRNA, across CRC stages. LOC285629 expression was significantly downregulated in advanced stages (Stage III and IV) compared to Stage I (Kruskal-Wallis Test; p = 0.0093). Further in-house validation showed that the expression of LOC285629 was upregulated in colorectal cancer tissues and cell lines compared to the normal counterparts, but was downregulated in advanced stages. By targeting LOC285629, the viability, proliferative abilities, invasiveness and resistance of colorectal cancer cells towards 5-fluorouracil were reduced. It was also discovered that LOC285629 may regulate cancer progression by targeting several different proteins, namely survivin, BCL-xL, progranulin, PDGF-AA, enolase 2 and p70S6 K.
CONCLUSION: Our findings suggest that LOC285629 may be further developed as a potential therapeutic target for CRC treatment.
