Background: Cadmium (Cd) exposure is a risk factor for cardiovascular disease (CVD); however, understanding the effects of Cd at the cellular level remains incomplete. Since growth differentiation factor-15 (GDF-15) is a cytokine produced in many cell types in response to tissue injury and inflammation that may capture several pathways between Cd and CVD, this study examined the relationship between blood Cd levels and serum GDF-15 concentrations in community-dwelling older adults.
Methods: Cd and GDF-15 were measured in 1942 non-smoking individuals aged 65+ with no previous history of CVD. The association of Cd with GDF-15 was evaluated in linear regression models that adjusted for sociodemographic, lifestyle and biological risk factors, inflammatory biomarkers (IL-6, C-reactive protein and neutrophil to lymphocyte ratio), and markers of vascular damage (NTproBNP and cTnT-hs).
Results: Geometric mean Cd exposure was 0.11 μg/L (0.09 in never- and 0.15 in former-smokers) and geometric mean GDF-15 was 1186.21 pg/mL (1182.67 in never- and 1191.66 in former-smokers). In multivariable analyses, we found a dose-response association between Cd levels and GDF-15: adjusted mean percentage differences in GDF-15 (95% confidence interval) per 2-fold increase in Cd concentrations in the overall non-smoking population and in never smokers were, respectively, 2.54% (1.01, 4.06) and 2.50% (0.47, 4.54). In spline regression, the dose-response relationship was progressive over the range of Cd concentrations with no significant departures from linearity.
Conclusions: Cd exposure may be related to enhanced GDF-15 expression. Future studies with repeated GDF-15 measurements should confirm the present findings to better understand the biological mechanisms underlying this association.

Background: Growth Differentiation Factor 15 (GDF15) has been described as influencing skeletal physiology. Nevertheless, no systematic appraisal of the effect of GDF15 on skeletal muscle tissues has been developed to the present day.
Objective: The aim of the present work was to review the evidence on the topic.

Colorectal cancer (CRC) ranks second in mortality worldwide while metastasis accounts for most CRC-related deaths. Thus, understanding cell migration, a crucial step in metastasis, is imperative for developing new therapies. Growth Differentiation Factor-15 (GDF15), a member of the Transforming Growth Factor β superfamily, is overexpressed in CRC and promotes metastasis with a so far unknown mechanism.

Phthalate exposure is linked to prostate enlargement through sex hormonal changes and oxidative stress. However, its role and action mechanism in prostate cancer remain unclear. This study examined two patient cohorts: 204 patients undergoing prostate biopsy (24 benign and 180 malignancies) and 85 with confirmed prostate cancer receiving robotic-assisted radical prostatectomy.

Background: Our previous research demonstrated that growth differentiation factor 15 (GDF15) exhibited superior predictive capability for metabolic dysfunction-associated steatohepatitis (MASH) development with an AUC of 0.86 at 10 years before disease diagnosis. However, the specific pathways and molecular mechanisms associated with GDF15 expression during MASH development remain to be fully investigated in humans.

Aims: Early identification of healthy subjects prone to develop cardiac dysfunction may be instrumental to prevention strategies. Our study aimed to evaluate whether circulating levels of growth differentiation factor-15 (GDF-15) could predict adverse changes in echocardiographic indexes of cardiac structure and function in an initially healthy populational familial cohort with a long follow-up (STANISLAS cohort).
Methods And Results: We evaluated 1679 participants (49 ± 14 years, 48% males) included in the fourth visit (V4) of the STANISLAS cohort with available GDF-15 measurements (Olink proteomic analysis) and echocardiographic parameters.
