Background: Coronavirus disease-2019 (COVID-19) results in acute lung injury. This study examined the usefulness of serum transforming growth factor-beta 1 (TGF-β1) and connective tissue growth factor (CTGF) levels in predicting disease severity in COVID-19 patients with pulmonary involvement.
Methods: Fifty patients with confirmed COVID-19 and pulmonary involvement between September 2020, and February 2021 (Group 1) and 45 healthy controls (Group 2) were classified into three subgroups based on clinical severity: moderate, severe, and critical pneumonia. Serum TGF-β1 and CTGF concentrations were measured on days 1 and 7 of admission in Group 1 using an enzyme-linked immunosorbent assay. These concentrations were also measured in control cases. The mean serum TGF-β1 and CTGF levels were then compared among COVID-19 patients, based on clinical severity.
Results: Significantly higher mean serum TGF-β1 and CTGF levels were observed on both days in Group 1 than in the control group. The mean serum TGF-β1 and CTGF levels on day 7 were also significantly higher than those on day 1 in Group 1. The critical patient group had the highest serum TGF-β1 and CTGF levels on both days, and the difference between this group and the moderate and severe pneumonia groups was significant. Cutoff values of 5.36 ng/mL for TGF-β1 and 626.2 pg/mL for CTGF emerged as predictors of COVID-19 with pulmonary involvement in receiver-operating characteristic curve analysis.
Conclusions: TGF-β1 and CTGF are potential markers that can distinguish COVID-19 patients with pulmonary involvement and indicate disease severity. These findings may be useful for initiating treatment for early-stage COVID-19.

Skin scar formation is a critical pathological process in wound healing, but its underlying regulatory mechanisms remain incompletely elucidated. By integrating analyses of Bulk-RNA seq and single-cell RNA sequencing (scRNA-seq) data, we identified that ferroptosis-related biological processes potentially play a key role in skin scar formation. Further mechanistic studies demonstrated that in human dermal fibroblast cells, the ferroptosis regulator TIMP metallopeptidase inhibitor 1 (TIMP1) significantly promotes fibroblast differentiation toward a mature phenotype through interactions with cystatin C (CST3), characterized by upregulated expression of myofibroblast differentiation markers such as α-smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF), along with enhanced cell proliferation and migration abilities.

The Hippo signaling pathway, a critical regulator of cell proliferation, apoptosis, and tumor progression, is often dysregulated in NSCLC and contributes to chemo-resistance. This study investigated the potential of epigallocatechin-3-gallate (EGCG), a green tea polyphenol, to overcome OSI resistance by modulating the Hippo signaling pathway, specifically through inhibition of the YAP-1 (Yes-associated protein)-TEAD (TEA domain transcription factor)-CTGF (connective tissue growth factor) axis.

Connective tissue growth factor (CTGF) is notably upregulated in scar tissue, making it a promising target for therapeutic intervention. Here, we have designed and screened an antisense oligonucleotide (ASO) that binds specifically to the exon five sequence of CTGF, with particular emphasis on the use of 2'-O-methoxyethyl (MOE) and locked nucleic acid (LNA) modifications to enhance stability and specificity. experiments demonstrated that both MOE-ASO#1 and LNA-ASO#1 significantly inhibited fibroblast proliferation and extracellular matrix protein expression.

The transcriptional activity of TEAD4 (transcriptional enhancer associated domain proteins), one of the final effectors of the Hippo pathway, can be dysregulated or mutated in cancer. Consequently, targeting the interaction between TEAD and its co-activator YAP (Yes Associated Protein) to disrupt the YAP:TEAD (Y:T) heterodimer has emerged as a promising anti-cancer strategy. Therefore, in this study, we aimed to identify novel scaffolds targeting the TEAD Interface 3 surface as effective anticancer agents against colorectal and ovarian cancer.

The effects of the phenolic compounds punicalagin and ellagic acid, derived from pomegranate, were analyzed on the gene expression of cultured human fibroblasts. The focus was placed on genes associated with growth factors, differentiation markers, and extracellular matrix (ECM) components, all of which play a crucial role in effective wound healing. The human dermal fibroblast cell line CCD-1064Sk was used, and the bioactive compounds punicalagin and ellagic acid were administered to cultured fibroblasts at concentrations of 10 and 10 M, respectively.
