Strategies for blocking the fibrogenic actions of connective tissue growth factor (CCN2): From pharmacological inhibition in vitro to targeted siRNA therapy in vivo

Connective tissue growth factor (CCN2) is a major pro-fibrotic factor that frequently acts downstream of transforming growth factor beta (TGF-β)-mediated fibrogenic pathways. Much of our knowledge of CCN2 in fibrosis has come from studies in which its production or activity have been experimentally attenuated. These studies, performed both in vitro and in animal models, have demonstrated the utility of pharmacological inhibitors (e.g. tumor necrosis factor alpha (TNF-α), prostaglandins, peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonists, statins, kinase inhibitors), neutralizing antibodies, antisense oligonucleotides, or small interfering RNA (siRNA) to probe the role of CCN2 in fibrogenic pathways. These investigations have allowed the mechanisms regulating CCN2 production to be more clearly defined, have shown that CCN2 is a rational anti-fibrotic target, and have established a framework for developing effective modalities of therapeutic intervention in vivo

Hormone replacement therapy in women with iatrogenic premature ovarian insufficiency after radiotherapy for cervical cancer:A retrospective cohort and survey study

Objectives: This study assessed the uptake of hormone replacement therapy (HRT) in cervical cancer patients with iatrogenic menopause. Survival in relation to HRT use was assessed via a retrospective chart study, and the severity of menopausal symptoms, motivations and barriers to starting HRT were examined via questionnaires. Study design: In total, 293 women under the age of 51 and treated with radiotherapy for cervical cancer between 2010 and 2020 were identified. Medical records were searched for information on HRT use. If still living, women were sent digital questionnaires addressing menopausal symptoms, quality of life (QoL) and potential barriers and motivations concerning HRT use. Univariable data were analysed using Mann-Whitney U, chi-square, and Fisher's exact test, while logistical regression was used to analyse relationships between certain variables and use of HRT and survival. Results: Overall HRT uptake was 78.1 %, which was related to age and Charlson Comorbidity Index, but independent of the duration of radiotherapy or FIGO stage. Overall survival was higher for HRT users (χ2(1) = 4.3, p = 0.038). Questionnaires were sent to 193 patients and 100 completed it (response rate 51.8 %). Main reasons for HRT use were relief of hot flushes and improvement in QoL. For women below age 51, QoL was indeed higher for current HRT users than for non-HRT users (EQ-index 0.8 vs. 0.7, p = 0.008). Conclusions: HRT prescription rate was inversely correlated with age. Survival was not negatively affected by HRT use. It is important to stress the benefits of HRT and address women's fears regarding its use.</p
