Product Details
Lentiviruses, part of the retroviridae family, are widely used for stable cell line establishment due to high
transduction efficiency, low immunogenicity, and durable expression. Unlike gammaretroviruses, lentiviruses infect
non-replicating cells, making them powerful tools for gene function studies. Creative Biogene offers a diverse
premade lentiviral collection with human, rat, and other organisms' genes, tagged or reporter options. Our
ready-to-use lentiviruses efficiently deliver specific target expression to various cell types, including primary
and non-dividing cells. For customized projects, utilize our top-notch lentiviral services.

Case Study
Case Study 1
Researchers employed lentiviral vectors to investigate the impact of Glaucocalyxin A (GLA) on gastric cancer (GC).
GLA-induced apoptosis in GC cells, involving increased caspase-3 activity and elevated levels of cleaved caspase-3
and cleaved PARP. The downregulation of Murine Double Minute Clone 2 (MDM2) and Ring Finger Protein 6 (RNF6) by GLA
was attributed to miR-3658, which GLA upregulated through demethylation and abrogation of EZH2-mediated epigenetic
silencing. The study indicates GLA's therapeutic potential for GC through posttranscriptional regulation of
oncogenes.
Figure 1. GLA treatment significantly downregulated oncogenes Mdm2 and
RNF6 in gastric cancer cells, as identified in our previous gene regulation screening. Human MDM2 and RNF6
lentivirus particles were from Creative Biogene, New York, USA. (Liu Y, et al., 2022)
Case Study 2
Ewing sarcomas commonly develop in the pelvic and stylopod bones, such as the femur and humerus, possibly due to the
transformation of mesenchymal stem/progenitor cells (MSCs) induced by the EWS-FLI1 oncogene. Researchers
utilized lentiviral transduction to investigate the impact of EWS-FLI1 on embryonic superficial zone (eSZ)
cells expressing posterior Hox genes in Ewing sarcoma tumorigenesis. They isolated eSZ cells from various bones,
revealing that stylopod eSZ cells are more susceptible to EWS-FLI1-induced transformation, consistent with
the predominant presentation of Ewing sarcoma in pelvic and stylopod bones. Surprisingly, loss of Hoxd13
had no impact on EWS-FLI1-induced transformation, indicating its dispensability in mouse MSCs. These
findings underscore anatomically-defined differences in MSCs contributing to the distinct susceptibility of skeletal
sites to Ewing sarcoma.
Figure 2. Researchers successfully isolated Hox+ eSZs from zeugopod
and stylopod, demonstrating their tolerance to lentiviral-mediated EWS-FLI1 expression. (Pfaltzgraff ER,
et al., 2019)
