Several studies have predicted the molecular interactions of the active ingredient of Spirulina platensis as an anti-inflammatory compound. However, these interaction studies did not review the modulation of the NF-κB activation pathway, which involves various factors. This study demonstrated the potential of the bioactive compounds of S. platensis for modulating immune function by reducing inflammation through the inhibition of the NF-κB activation pathway. Phycocyanobilin was predicted to have good potential for molecular docking with multisubunit IκB kinase (IKK)1/IKKA, IKK2/IKKB, NF-κB-inducing kinase, and the IκBα/NF-κB complex. Furthermore, β-carotene exhibited good potential for interactions with NF-κB essential modulator/IKK and the NF-κB complex, and α-glucan had the potential for interactions with COX-2. Therefore, supplementation with S. platensisand its bioactive compounds is expected to provide optimal benefits.

Relative Expression of HIF-1α mRNA in Rat Heart, Brain and Blood During Induced Systemic Hypoxia. Hypoxia is a pathological condition in which the body as a whole or region of the body (tissue or cell) deprived of adequate oxygen supply. The transcriptional regulator hypoxia inducible factor-1 (HIF-1) is an essential mediator of O2 homeostasis. Unlike the β sub unit (HIF-1β), the activity of HIF-1α is controlled in an oxygen-dependent manner. It has been reported that the stability and expression of HIF-1α during hypoxia is remarkably higher than those under normoxic conditions.The aim of this study was to analyze the adaptive tissue responses during induced systemic hypoxia by comparation of relative expression of mRNA HIF-1α in rat heart, brain and blood. Twenty-five male Sprague Dawley rats were subjected to systemic hypoxia by placing them in the hypoxic chamber supplied by 8-10% of O2 for 0, 1, 7, 14 and 21 days, respectively. The relative expression level of HIF-1α mRNA in brain, heart and leucocyte cells were analyzed using quantitative RT-PCR assay (Real Time PCR) based on Pfaff’s formula. This study demonstrates that the increased of relative expression of HIF-1α mRNA during induced systemic hypoxia reached its maximum level at day 7 (in heart) or at day 14 (in brain), whereas in leucocyte cells the stimulation of HIF-1α expression was intensively maintained up to 21 days although the expression has reached the remarkably high level. We could conclude that HIF-1α as an oxygen sensing during systemic hypoxia has different capacity and sensitivity in brain, heart and blood tissues, due to the importance of oxygen homeostasis in each tissue

Pro- and anti-inflammatory mediators need to be released in a balanced way to maintain a healthy state as we age. One important regulatory element in the equilibrium of pro- and anti-inflammatory mediators is NF-κB. The purpose of this study was to examine how S. platensis affected the control of inflammatory mediators in young, healthy, emerging adults and adults in rats. In this investigation, 200 mg/kg BW of S. platensis extract was administered to six groups of male Wistar rats, ages 12, 18, and 24 weeks, along with a control group. In both the treatment and control groups, NF-κB p65 protein expression was lower at 24 weeks than it was at 12 and 18 weeks. TNF-α and COX-2 proteins were lower in the treatment group than in the control group. All age groups in the treatment group had higher levels of IL-10 protein than the control group. The quantity of NF-κB p65 was positively correlated with COX-2 and TNF-α. By raising the concentration of NF-κB p65, the ethanolic extract of S. platensis altered a mediator of cellular immunity. A decrease followed this in TNF-α and COX-2 and a rise in IL-10 in the rat spleen at different ages.

Background: Hypertensive disorders, particularly preeclampsia, are major contributors to maternal mortality and neonatal morbidity. Angiogenic imbalance plays a critical role in placental ischemia, a hallmark of preeclampsia. Purpose: This study aimed to investigate the roles of endoglin, soluble endoglin (sEndoglin), and matrix metalloproteinase-14 (MMP-14) in the angiogenic imbalance observed in preeclampsia placentas compared to normal-term placentas. Method: A cross-sectional study was conducted using 68 placental samples: 34 from normal-term pregnancies and 34 from preeclampsia cases. Concentrations of endoglin, sEndoglin, and MMP-14 were measured using the sandwich ELISA method, and protein levels were determined using the Christian Warburg method. Data were analyzed using SPSS version 20. Results: The concentration of endoglin in preeclampsia placentas was slightly higher (1.37 [0.2–2.2] ng/μg protein) compared to normal placentas (1.12 [0.6–14.1] ng/μg protein), although the difference was not statistically significant. In contrast, sEndoglin (0.05 [0.0–0.01] ng/μg protein vs. 0.02 [0.0–0.3] ng/μg protein) and MMP-14 (0.14 [0.1–0.6] ng/μg protein vs. 0.11 [0.1–1.3] ng/μg protein) concentrations were significantly higher in preeclampsia placentas compared to normal placentas. All parameters showed a gradual decrease with advancing gestational age. sEndoglin and MMP-14 demonstrated a strong positive correlation (r = 0.658, p < 0.001), while endoglin and MMP-14 exhibited a moderate positive correlation (r = 0.554, p < 0.001). Conclusion: Endoglin, sEndoglin, and MMP-14 were differentially expressed in preeclampsia placentas, with sEndoglin and MMP-14 significantly elevated. These findings highlight their potential role in angiogenic imbalance and may provide insight into the pathophysiology of preeclampsia.
