Abstract

Iron overload, often arising from repeated transfusions in thalassemia major, disrupts iron homeostasis and induces oxidative stress. Deferasirox is a widely used oral chelator, yet its effects on splenic iron-regulatory gene expression remain unclear. This study investigated the impact of deferasirox on ferritin heavy chain (Fth1), ferroportin (Slc40a1), and heme oxygenase-1 (Hmox1) expression in a rat model of splenic iron overload. Eighteen male Wistar rats were randomly assigned into three groups (n = 6 each): normal (N), iron dextran-induced overload without treatment (KN), and iron overload treated with deferasirox (KP). Gene expression was quantified by real-time PCR using the 2−ΔΔCT (Livak) method, with statistical analysis performed via one-way ANOVA and Tukey’s post hoc test. Iron overload significantly upregulated Fth1 (2.26-fold) and Slc40a1 (1.72-fold) versus controls (p < 0.05). Deferasirox treatment reduced Fth1 (3.28-fold decrease) and Slc40a1 (1.15-fold reduction) relative to untreated overload, though not significantly (p > 0.05). In contrast, Hmox1 expression markedly increased (55.25-fold, p < 0.05) following deferasirox administration. These results indicate that deferasirox selectively modulates splenic iron-regulatory genes, suggesting both chelation and adaptive stress-response mechanisms, thereby supporting its therapeutic role in managing iron overload.

Abstract

Indonesia is the second largest supplier of white shrimp (Litopenaeus vannamei, Boone 1931) in the USA market. Hence, the need for its sustainable production and improved growth. Probiotics, among others, are known for their growth enhancing attributes. Therefore, this study was conducted to determine the effects of powder and liquid probiotics on the growth of white shrimps at the Minaloka Jaya shrimp ponds, Grabag District, Purwerojo Regency, Central Java. The shrimps were cultivated for 60 days and applied with three probiotic treatments, namely commercial liquid probiotics with dosage of 10 mL/kg feed, powder probiotics with dosage of 10 g/kg feed and liquid probiotic with dosage of 10 mL/kg feed. Each probiotic preparation was administered four times a day to over 150,000 vannamei shrimps which were cultured in a semi-intensive system. Probiotics in powder and liquid forms contain Lactobacillus fermentum, L acidophilus, L. plantarum, L, curvatus, Bacillus licheniformis, B. subtilis, and B. polimyxa. B. megaterium, B. coagulans, Pseudomonasputida, Nitrosomonas sp. and Nitrobacter sp. Using the Randomized Block Design (RBD), the three treatments were replicated five times. The application of probiotics in both powder and liquid forms had increased the growth yield of the vannamei shrimp. However, the powder probiotic had shown better growth performance than the commercial liquid probiotics and liquid preparation of probiotics. Probiotic powder form provides a specific growth rate (SGR) of 8.18%, absolute body length of 9.68 cm, absolute biomass of 6.78 g, and feed conversion ratio (FCR) of 1.93.
