Abstract

Previous studies of Lactiplantibacillus plantarum IIA-1A5 have shown its potential as a probiotic in modulating gut microbiota and providing health benefits; however, its effects during pregnancy remain underexplored. The aim of this study was to assess the safety of fermented milk enriched with L. plantarum IIA-IA5 in pregnant mice. An experimental study was conducted at Universitas Andalas, Padang, Indonesia. Two groups of pregnant mice (Mus musculus L.) were used, each with six mice. The control group received sterilized milk (10 mL/kg body weight (BW)), while the intervention group was given fermented milk containing L. plantarum IIA-1A5 (107 colony forming unit (CFU)/mL). The evaluated outcomes included maternal weight changes, fetal counts and measurements, and assessments of fetal morphology and skeletal development. Results indicated that the morphology of fetuses showed no significant differences between the control and intervention groups; both groups demonstrated normal development with no detected resorption sites, growth retardation, or hemorrhage. For skeletal development, both groups had the same bone counts, including frontal, parietal, intraparietal, exoccipital, supraoccipital, nasal, pre-maxilla, mandibular, thoracal, lumbar, sternum, and extremities. This study highlights that L. plantarum IIA-1A5-enriched fermented milk was safe, as no significant morphological or bone developmental abnormalities were observed, indicating its potential as a dietary supplement to support pregnancy health. However, further studies involving larger sample sizes may be needed to provide a more comprehensive assessment of its outcomes and safety.

Abstract

Lactococcus lactis D4 is a probiotic produced through the fermentation of buffalo milk in bamboo, namely "dadih", a traditional food from West Sumatera, Indonesia. To the best of our knowledge, no specific research has investigated the effects of L. lactis D4, derived from dadih extraction, on colorectal cancer or its potential clinical applications. Therefore, the aim of this study was to evaluate the potential of L. lactis D4 from dadih to inhibit colorectal cancer growth in rat models, with a focus on its effects on cell proliferation, apoptosis, and inflammatory responses. An in vivo study was conducted using 37 male Sprague-Dawley rats, allocated into five groups: (1) control (no treatment), (2) dysplasia (induced with 1,2-dimethylhydrazine until dysplasia developed), (3) dysplasia + L. lactis D4 (induced with 1,2-dimethylhydrazine, then treated with L. lactis D4 after dysplasia confirmation), (4) cancer (induced with 1,2-dimethylhydrazine until cancer was confirmed), and (5) cancer + L. lactis D4 (induced with 1,2-dimethylhydrazine until cancer was confirmed, then treated with L. lactis D4 for 15 days). The effects of L. lactis D4 on cancer progression were assessed through immunohistochemical analysis of cell proliferation (cyclin D1, Bcl-2), apoptosis (p53, caspase-3), and inflammation (nuclear factor-κB (NF-κB) and cyclooxygenase-2 (COX-2)). This study found that L. lactis D4 treatment reduced adenocarcinoma and dysplasia severity in colorectal cancer models through significant reduction in cyclin D1, Bcl-2, NF-κB, and COX-2 expression observed across all groups (p<0.01), although changes in dysplasia and cancer subgroups were not statistically significant (p>0.05). No statistically significant change was noted in p53 expression (p=0.518), whereas caspase-3 expression varied significantly across groups (p=0.010). In conclusion, L. lactis D4 reduces the expression of cyclin D1, Bcl-2, NF-κB, and COX-2 proteins, offering insights into its potential to modulating proliferation and inflammation in colorectal cancer growth.
