Article Abstract
Objective: To transfer the gene encoding mammalian aFGF to rabbit corneal endothelial cell and determine transfection efficiency and the effect of Ad-aFGF on proliferation of RCEC.
Methods: Replication-defective adenovirus was used to deliver the LacZ reporter gene to RCEC to determine transfection efficiency by X-gal staining. A cDNA encoding mammalian aFGF was cloned into an adenoviral vector that was used to transfect RCEC. The expression of aFGF gene mRNA and protein were demonstrated by Reverse transcription PCR and Western blot respectively. The effect of Ad-aFGF on proliferation of RCEC was determined by MTT assay.
Results: RT-PCR and Western blot from RCEC infected with Ad-aFGF for 48 h detected a specific cDNA amplification and protein expression of aFGF gene, and no positive result in control cells. Consistently, RCEC infected by MOI 20 of Ad-aFGF demonstrated an enhanced RCEC proliferation compared to controls (F = 217.107, P < 0.05).
Conclusion: Adenoviral-mediated expression of aFGF can stimulate the proliferation of RCEC.

To investigate the effect of recombinant human aFGF (rhaFGF) on acute wounds in a diabetic mouse model focusing on the transition from acute inflammation to chronic inflammation. Diabetes mellitus (DM) mouse models were induced through intraperitoneal injection of streptozotocin and acute diabetic wounds were created on their hind paws. The mice were divided into four groups: Con, Con + rhaFGF, DM, and DM + rhaFGF.

The urgent need to enhance the early vascularization of dermal substitutes to improve their repair efficiency in skin defect wound presents a significant challenge. This study investigated the impact of dual gene-activated scaffolds (DGAS-M), which combined nanocomposite particles (NPs) encapsulating plasmid DNA (pDNA) of VEGF and aFGF, with the aim of enhancing early vascularization and vascular maturation. In this study, we used the liposomes to encapsulate pDNA and loaded on PLGA knitted mesh-reinforced collagen/chitosan scaffolds (PLGAm/CCS) to prepare DGAS-M.

Background: Chronic diabetic wounds pose a significant clinical challenge due to the limited efficacy of current treatments. This study aimed to investigate the role and potential mechanisms of adipose-derived mesenchymal stem cells (ADSCs) overexpressing acidic fibroblast growth factor (aFGF) in diabetic wound healing in a rat model.
Methods: ADSCs were genetically modified to achieve stable overexpression of aFGF.
Transcriptional Rearrangements Associated with Thermal Stress and Preadaptation in Baikal Whitefish ().

Article Synopsis
- The study examines how juvenile Baikal whitefish, both preadapted and non-adapted, respond at the genetic level to heat shock after being exposed to temperature changes during their development.
- Preadapted fish experienced a controlled thermal rise during their growth, while both groups were tested under standard and increased temperature conditions to measure gene expression responses.
- The findings show that preadapted fish had heightened expression in genes related to immune response and growth, while non-adapted fish showed increased activity in metabolism-related genes, highlighting differences in how these two groups handle thermal stress.

Fibroblast Growth Factor 1 (Fgf1), also known as acidic FGF (aFGF), is involved in the regulation of various biological processes, ranging from development to disease pathogenesis. It is a single chain polypeptide and is highly expressed in adult brain and kidney tissues. Its expression has been shown to be directed by multiple tissue-specific promoters, which generate transcripts of varying lengths.
