Article Title: SLCO4A1-AS1 promotes colorectal tumourigenesis by regulating Cdk2/c-Myc signalling.

doi: 10.1186/s12929-022-00789-z

Figure Lengend Snippet: Fig. 2 Promoter hypomethylation promotes SLCO4A1-AS1 expression in CRC. a Schematic map illustrating a predicted CpG island and its DNA methylation probes in the promoter of SLCO4A1-AS1. TSS, transcription start site. b The β-value of methylation of SLCO4A1-AS1 was lower in tumour samples than in normal tissues according to the CRC dataset of TCGA. The β-value of methylation of SLCO4A1-AS1 was linearly related to SLCO4A1-AS1 expression in CRC tissues from TCGA (c) and cell lines from CCLE (d). e Relative expression of SLCO4A1-AS1 in CRC cell lines was measured using qRT-PCR (the left panel). The methylation levels of SLCO4A1-AS1 in CRC cell lines and leukocyte cells were determined by bisulfite sequencing PCR. A total of 5 individual clones were randomly picked for sequencing (the right panel). f The mean methylation levels of these CpG sites were negatively associated with the expression levels of SLCO4A1-AS1 in CRC cells. g SLCO4A1-AS1 expression in CRC cells treated with DNA methyltransferase inhibitor (5-aza-dC). h DNA methylation analyses of SLCO4A1-AS1 in paired CRC tissues and noncancerous tissues using methylation-specific PCR assay.

Article Title: Novel Breast-Specific Long Non-coding RNA LINC00993 Acts as a Tumor Suppressor in Triple-Negative Breast Cancer

doi: 10.3389/fonc.2019.01325

Figure Lengend Snippet: LINC00993 suppresses the growth of triple-negative breast cancer (TNBC) cells in vitro . (A) Structure of LINC00993 expression plasmid for adenovirus. (B) LINC00993 expression adenovirus infection efficiency showed by fluorescence microscope in MDA-MB-231 cells. Original magnification, ×400. Scale bars, 50 μm. (C) Expression of LINC00993 detected by qRT-PCR. MDA-MB-231 cells were infected by adenovirus for 24 h, and RNA was extracted. (D) Image of clone formation assay. (E) Number of clones were counted 2 weeks after plantation. (F) MDA-MB-231 cells were planted into 24-well plates. Twenty-four hours later, adenovirus was added to each well. Three wells of cells were digested and counted every 24 h. (G) LINC00993 expression caused apoptosis shown by TUNEL assay. Green points reflected apoptosis, and we used DAPI to stain DNA. Positive control cells were treated with DNase I, negative control cells were collected without adding TUNEL reaction buffer. Original magnification, ×100. Scale bars, 50 μm. (H) Effect of LINC00993 on cell cycle detected by flow cytometry. (I) Flow cytometry cell cycle results shown in a bar plot. (J) Invasive ability tested by Transwell assay. Twenty thousand cells were plated in each well, cells were observed after 24 h of incubation. (K) Bar plot for the number of cells that migrated across the membrane. *** P < 0.001, based on Student's t -test. Data were presented as mean ± SEM.

doi: 10.1038/gt.2008.77

Figure Lengend Snippet: Figure 3 Mouse UL16-binding protein-like transcript 1 E (MULT1E)/FasTI induces apoptosis. A total of 1 106 cells of TC-1 and clones L-5, L-7 and L-10 were treated with 1 mg/ml NKG2D/Fc for 16 h. The cells were then analyzed for apoptosis and necrosis using Annexin V assay (a–c) or caspase-3 assay (d) according to the manufacturers’ protocols. (a) An example of the fluorescence-activated cell sorting (FACS) data. (b, c) Summaries of data from three separate experiments. The statistical analyses were conducted between the controls (open bars) and NKG2D/Fc-treated cells (solid bars) using two-way analysis of variance (ANOVA). The difference between NKG2D/Fc-treated L-5 cells and NKG2D/Fc-treated L-10 cells was also compared using Student’s t-test. *Po0.05; **Po0.01 and ***Po0.001.

Article Snippet: Induction of apoptosis in cells expressing the fusion protein To determine if cells expressing the fusion protein can be induced to undergo apoptosis, one million cells of TC-1 and clones L-5, L-7 and L-10 were treated with 1 mg/ml of NKG2D/Fc for 16 h. Apoptosis of the cells was measured using two systems: a TACS Annexin V-FITC Apoptosis Kit (R&D Systems) and a caspase-3 fluorometric assay (R&D Systems).
