Molecular biology techniques are indispensable tools in biochemistry, genetics, and biophysics. These techniques involve the manipulation and analysis of DNA and RNA, enabling groundbreaking advances in understanding genetic processes. Among these methods, gene synthesis and cloning are pivotal in synthetic biology, allowing researchers to create artificial genes and study protein function. Gene synthesis, in particular, facilitates the creation of completely synthetic double-stranded DNA molecules, free from the constraints of preexisting sequences. This method has been used to generate functional bacterial or yeast chromosomes, even ones containing up to one million base pairs.

At Creative Biogene, we provide comprehensive molecular biology services, focusing on gene synthesis & cloning, gene mutation, plasmid preparation, recombinant protein expression, oligonucleotide synthesis, and DNA methylation.

Client Case Studies & Research Outcomes

Case Study 1

CTLA-4 insufficiency is a genetic immune disorder characterized by an impaired ability to regulate immune responses, often resulting in severe autoimmune diseases. A promising therapeutic approach is autologous T-cell gene therapy, which avoids the complications associated with allogeneic hematopoietic stem cell transplantation. Researchers in this study developed a homology-directed repair (HDR) gene-editing strategy to restore CTLA-4 function by inserting the CTLA-4 cDNA into its genomic locus in primary human T cells. This innovative approach regulated CTLA-4 expression in CD4+ T cells and restored functional transendocytosis of CD80 and CD86, key immune regulatory proteins. Experiments with patient-derived T cells demonstrated successful protein expression recovery, while in vivo studies using gene-corrected T cells in CTLA-4−/− mice showed the potential to prevent lymphoproliferation and ameliorate immune dysregulation.

The researchers utilized Creative Biogene's Oligonucleotide Synthesis Service to obtain high-quality small double-stranded oligonucleotides (dsODNs) essential for HDR editing. After synthesis, the dsODNs were integrated into RNP complexes for T-cell editing. Genomic DNA samples, post-editing, were shipped to Creative Biogene, where advanced next-generation sequencing (NGS) and data analysis were conducted.

Figure 1 illustrates the CRISPR-Cas9 approach for targeting the CTLA-4 gene locus, displaying the mutational landscape of CTLA-4 insufficiency, the design of the homology-directed repair donor, and the average gene repair efficiency across multiple healthy donors. (doi: 10.1126/scitranslmed.abn5811)Figure 1. The researchers utilized CRISPR-Cas9 to target the CTLA-4 locus and repair a point mutation using HDR. High-quality dsODNs synthesized by Creative Biogene facilitated precise gene editing, while next-generation sequencing verified HDR efficiency, achieving an average GFP expression rate of 55.83%.

Case Study 2

ABI1, an adaptor protein, regulates actin polymerization and cell signaling pathways. Dysregulation of ABI1 has been implicated in cancer development, influencing inflammation and cell survival processes. To explore ABI1's functions, the researchers employed proximity-dependent labeling (PDL) combined with mass spectrometry to map its interactome. Using a novel data filtering strategy, they identified 212 proximal interactors, including components of the WAVE2 complex and the TAK1-NF-κB signaling pathway. Functional assays further revealed that ABI1 modulates TAK1/RIPK1-dependent apoptosis, offering new insights into its role in cancer biology.

The researchers utilized Creative Biogene's Gene Synthesis and Cloning Service to synthesize the pcDNA3.1(+) construct containing the TurboID linker and ABI1 sequence. This construct was crucial for generating MSCV-IRES-GFP retroviruses, enabling precise expression of ABI1 in NIH/3T3 cells.

Figure 2 developed MSCV-TurboID vectors for ABI1 proximity labeling, established stable cell lines through single-cell sorting, and characterized cellular behaviors to prepare for comprehensive protein interaction mapping using PDL/MS. (doi: 10.1002/1878-0261.13374)Figure 2. The researchers developed ABI1 proximity-dependent labeling (PDL) tools using MSCV-TurboID vectors. These constructs facilitated retroviral transduction of NIH/3T3 cells, enabling the generation of GFP-positive cell lines for interactome analysis, wound-healing assays, and EdU incorporation studies. (Petersen M, et al., 2023)

Case Study 3

Verticillium wilt of olive (VWO), caused by Verticillium dahliae, severely affects olive crops by disrupting vascular function. Tolerant cultivars offer an effective management strategy, but understanding their root-level defense mechanisms remains incomplete. Current research highlights structural, genetic, biochemical, and physiological differences between tolerant and susceptible cultivars, shedding light on how tolerance is mediated at multiple mechanistic levels.

The researchers investigated six olive cultivars with varying VWO tolerance, focusing on root architecture, lignin content, and defense-related gene expression. Using primers custom-designed and synthesized by Creative Biogene, they conducted time-course qPCR analyses to evaluate the expression of genes involved in lignin biosynthesis (e.g., C4H and CO-MT), fungal cell wall degradation (β-1.3-glucanase), and innate immunity activation (BAK1 and WRKY5). Their findings revealed that tolerant cultivars exhibited higher basal lignin levels, less branched roots, and a rapid genetic response post-inoculation.

Figure 3 depicts the time-course expression patterns of β-1,3 glucanase and BAK1 genes in control and Verticillium dahliae-inoculated plants, highlighting gene expression differences between tolerant and susceptible cultivars with statistical significance markers. (doi: 10.3389/fpls.2022.863055)Figure 3. The researchers employed a time-course gene expression analysis comparing β-1,3 glucanase and BAK1 gene expressions in control and Verticillium dahliae-inoculated plants across tolerant and susceptible cultivars.
