RESUMEN
The current scientific literature has extensively explored the potential role of proteasome inhibitors (PIs) in the NF-κB pathway of leukemia and lymphoma. The ubiquitin-proteasome system (UPS) is a critical component in regulating protein degradation in eukaryotic cells. PIs, such as BTZ, are used to target the 26S proteasome in hematologic malignancies, resulting in the prevention of the degradation of tumor suppressor proteins, the activation of intrinsic mitochondrial-dependent cell death, and the inhibition of the NF-κB signaling pathway. NF-κB is a transcription factor that plays a critical role in the regulation of apoptosis, cell proliferation, differentiation, inflammation, angiogenesis, and tumor migration. Despite the successful use of PIs in various hematologic malignancies, there are limitations such as resistant to these inhibitors. Some reports suggest that PIs can induce NF-κB activation, which increases the survival of malignant cells. This article discusses the various aspects of PIs' effects on the NF-κB pathway and their limitations. Video Abstract.

BACKGROUND: Several studies have demonstrated the improvement in serum lipoproteins by statins in patients with Chronic Kidney Diseases (CKDs), including End-Stage Renal Disease (ESRD). However, the results of these studies are inconclusive. AIM: We aimed to systematically investigate the effect of statins on lipid profiles of patients with CKD by performing a meta-analysis of Randomized Controlled Trials (RCTs). METHODS: Major electronic databases (Scopus, MEDLINE/PubMed, and ISI Web of Science) were searched from inception to August, 2023, to find randomized controlled trials (RCTs) evaluating the effect of different statins on serum lipoproteins in CKD patients. Weighted Mean Difference (WMD) with 95% Confidence Intervals (CI) was used to estimate the effect size. Trial Sequential Analysis (TSA) was performed to confirm the robustness of the evidence. RESULTS: A total of 18 publications were identified. It was found that statins reduced serum levels of Low-Density Lipoprotein (LDL)-C (WMD = -27.81 mg/dl, 95% CI = -34.47 to -21.15, P < 0.001) and total cholesterol (WMD = -25.44 mg/dl, 95% CI = -34.71 to -16.18, P < 0.001) in patients with CKD compared to the control group. Nonetheless, the effect of statins on High-Density Lipoprotein (HDL)-C (WMD = 0.57 mg/dl, 95% CI = -0.71 to 1.85, P = 0.38) and Triglyceride (TG) (WMD = -9.08 mg/dl, 95% CI = -22.22 to 2.06, P = 0.11) was not statistically significant. The results of TSA confirmed the robustness of the evidence and were consistent with the pooled effect size. The findings of subgroup analysis and time response analysis were also significant. CONCLUSION: It was found that statin therapy reduced the levels of LDL-C and total cholesterol in patients with CKD.

Objectives: In this study, the adjuvant activity of aqueous and alcoholic extracts of propolis was examined on the inactivated herpes simplex virus-1 (HSV-1). Materials and Methods: BALB/C mice were administered with inactivated (HSV-1; the KOS strain) plus alcoholic and aqueous extracts, followed by assessment of the cellular and humoral immune responses. Results: Alcoholic and aqueous extracts, as an adjuvant, revealed a significant increase in lymphocyte proliferation and cytotoxic T lymphocyte (CTL) responses versus the HSV-1 group. In addition, HSV-1 plus alcoholic extract showed a remarkable increase in IFN-γ cytokine and IFN-γ/IL-4 ratio. On the other hand, both alcoholic and aqueous extracts in the HSV-1 vaccine suppressed the IL-4 cytokine response as compared with the HSV-1 vaccine. In addition, HSV-1 plus alcoholic extract showed a significant increment in IgG1, IgG2a, and IgG2b isotypes as compared with the HSV-1 vaccine. Conclusion: Propolis extracts seem to modulate the immune response against inactivated HSV-1 model and can be used as a suitable vaccine adjuvant or a component of a complex adjuvant against infectious diseases.
