Oncogenic potential of bcl-2 demonstrated by gene transfer.
Reed JC, Cuddy M, Slabiak T, Croce CM, Nowell PC
Follicular lymphoma is the most common human B-cell malignancy in the United States and Western Europe. Most of the tumours contain t(14;18) chromosome translocations involving the human bcl-2 gene. Translocation of bcl-2 sequences from chromosome 18 into the transcriptionally active immunoglobulin locus at chromosome band 14q32 in B cells deregulates bcl-2 gene expression, resulting in the accumulation of high levels of bcl-2 messenger. Human bcl-2 transcripts generate two proteins, p26 bcl-2-alpha and p22 bcl-2-beta, by virtue of alternative splice-site selection. Both proteins have in common their first 196 NH2-terminal amino acids but share little similarity with other sequences in a data bank. Although the biological and biochemical functions of bcl-2 are unknown, recent subcellular localization studies indicate that p26 bcl-2-alpha associates with cellular membranes, consistent with a stretch of hydrophobic amino acids in its carboxy terminus. The bcl-2 gene may represent a novel oncogene having no known retroviral counterpart. Here we demonstrate the oncogenic potential of bcl-2 through a gene transfer approach. Nature. 1988 Nov 17;336(6196):259-61.

Molecular analysis of mbcl-2: structure and expression of the murine gene homologous to the human gene involved in follicular lymphoma.
Negrini M, Silini E, Kozak C, Tsujimoto Y, Croce CM
We have cloned the mouse bcl-2 (mbcl-2) genomic locus and analyzed it in detail. The gene is comprised of two exons separated by more than 15 kb. Two species of mRNAs are produced, and DNA sequencing analysis shows that they code for two proteins differing at their C terminus: a 7.5 kb transcript codes for a polypeptide of 236 amino acids, mbcl-2 alpha, and a 2.4 kb transcript, which derives from the 5' exon only, codes for a protein of 199 amino acids, mbcl-2 beta. The gene is characterized by very long (5' about 1.4 kb, and 3' about 5.1 kb) untranslated regions surrounding the relatively short coding region. We have mapped the 5' end of the mbcl-2 mRNAs by S1 protection analysis, and we have analyzed the promoter region. The expression of the mbcl-2 gene was analyzed in different cell lines and in mouse tissues. Expression is tissue-specific in adult tissues: spleen and thymus express the highest level of mbcl-2 transcripts. The mbcl-2 gene maps to mouse chromosome 1. Cell. 1987 May 22;49(4):455-63.

miRNA	Regulation	Description	Pubmed
hsa-miR-15a	overexpression by mature miRNA transfection	Then we investigated whether both miRNAs affect Bcl2 protein expression or this effect is restricted to only one of them.We have transiently transfected miR-15a and miR-16-1 sense and antisense oligo RNAs into the same MEG-01 cell line. As shown in Fig. 2B, separate transfections of miR-15a-sense and miR-16-1-sense, respectively, completely abolished BCL2 expression,whereas transfection of antisense RNAs did not. Similar data were obtained by cotransfection with both sense RNAs or both antisense RNAs, confirming that both miR-15a and miR-16-1 influence Bcl2 protein expression.	Ref.
hsa-miR-15a	overexpression by mature miRNA transfection	We haveevaluated mRNA levels by amplifying BCL2 cDNA from cells transfected with the pSR-miR-15_16-WT or with specific miR-15a and miR-16-1 RNA oligos by RT-PCR. No differences in the levels of BCL2 expression were observed between any of these samples and control cells (untransfected or transfected with the empty vector) (Fig. 2B). This result demonstrates that miR-15a and miR-16-1 do not affect mRNA stability and regulate Bcl2 expression at the posttranscriptional level.	Ref.
hsa-miR-15a/hsa-miR-16	overexpression	By proteomics analysis, we identified proteins whose intensity was reduced 4-fold or more in the pRS15/16 group with respect to the pRS-E group. We isolated 27 different proteins (Table 3 and SI Table 9). Interestingly, BCL2, which we had already shown as a target of miR-15a/16-1 (22), and WT1, another predicted target of these miRNAs, were identified. The targeted proteins have a variety of biological functions and can be grouped into four groups. The first group includes proteins that play a role in regulation of cell growth and cell cycle (Ruvbl1, Anxa2, Rcn1, Cct7, Sugt1, Cdc2, Psf1), another category is formed by antiapoptotic proteins (Grp78, Bcl2,Pdia2), and proteins involved in human tumorigenesis, either as oncogenes, or as tumor-suppressor genes (Wt1, MageB3, Rab9B).	Ref.
hsa-miR-15a/hsa-miR-16	overexpression	To validate the results obtained by transcriptomic or proteomic analyses, we assayed the expression of nine genes (four identified by the EST microarray, two by proteomics, and three identified by neither of the techniques and therefore considered as negative controls), by qRT-PCR in MEG-01 cells transfected with pRS15/16 or pRS-E (control). As shown in Fig. 2A, the transfection with miR-15a/16-1 reduces the expression of both microarray identified mRNAs (PDCD4, RAB21, IGSF4, SCAP2) and proteomics identified proteins (Bcl2, Wt1).	Ref.

hsa-miR-16	overexpression by mature miRNA transfection	We haveevaluated mRNA levels by amplifying BCL2 cDNA from cells transfected with the pSR-miR-15_16-WT or with specific miR-15a and miR-16-1 RNA oligos by RT-PCR. No differences in the levels of BCL2 expression were observed between any of these samples and control cells (untransfected or transfected with the empty vector) (Fig. 2B). This result demonstrates that miR-15a and miR-16-1 do not affect mRNA stability and regulate Bcl2 expression at the posttranscriptional level.	Ref.
hsa-miR-34a	downregulation by LNA antisense miRNA oligonucleot	To inhibit all three miRNA34 members, we cotransfected Wi38 cells with antisense locked nucleic acid (LNA) oligonucleotides (miRNA34as) targeting all three isoforms. Inhibition of miRNA34 in Wi38 cells led to an increase in BCL2 levels within 36 hr (Figure 4C).	Ref.
