Article Abstract
The aim of this study was to investigate how myeloperoxidase (MPO) G-463A gene polymorphism and enzyme levels varied among patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) and to find the relationship between the MPO gene, enzyme levels, and clinical parameters. We studied the sera from 40 healthy volunteers, patients with CLL (n = 34) and MM (n = 28). In subjects with homozygote GG genotype, MPO levels were higher in the patients with both CLL and MM than in the control group. This difference was statistically significant in patients with CLL. In conclusion, homozygote GG genotype is found to be associated with an increasing amount of serum MPO. In accordance with the results of the study, we assess that the increase in the MPO enzyme level in the patient groups with CLL and MM generated bactericidal effects as well as the increased formation of ROP, thus setting off a pro-cell death pathway and playing a role on the pathogenesis of lymphoproliferative malignancies through this mechanism.

Alopecia areata (AA) is an autoimmune condition marked by hair loss, linked to inflammatory processes involving the interleukin-1 receptor type 1 (IL-1R1) pathway. This study aims to explore the relationship between IL-1R1 gene expression, serum IL-1R1 levels, and hsa-miR-19b-3p in relation to AA severity. Using a case-control design, we assessed 100 AA patients and 100 healthy controls, measuring serum IL-1R1 through enzyme-linked immunosorbent assay (ELISA) and analyzing IL-1R1 gene and hsa-miR-19b-3p expression levels via quantitative real-time PCR (qRT-PCR).

Background: The cerebral Renin-Angiotensin System might have a role in anxiety and depression development.
Objective: We explored the effects of Angiotensin II Type 1 receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACE-Is) on anxiety and depression in Parkinson's Disease (PD).
Methods: Four hundred and twenty-three newly diagnosed drug-naïve PD patients were evaluated using the State-Trait Anxiety Inventory (STAI) and Geriatric Depression Scale (GDS-15) tests and were monitored at baseline and for up to 3 years.
Construction of Escherichia coli cell factory for efficient synthesis of indigo.

Indigo is widely used in dyes, medicines and semiconductors materials due to its excellent dyeing efficiency, antibacterial, antiviral, anticancer, anti-corrosion, and thermostability properties. Here, a biosynthetic pathway for indigo was designed, integrating two enzymes (EcTnaA, MaFMO) into a higher L-tryptophan-producing the strain Escherichia coli TRP. However, the lower catalytic activity of MaFMO was a bottleneck for increasing indigo titers.

Sulfur metabolism is an essential aspect of fungal physiology and pathogenicity. Fungal sulfur metabolism comprises anabolic and catabolic routes that are not well conserved in mammals, therefore is considered a promising source of prospective novel antifungal targets. To gain insight into sulfur-related metabolism during infection, we used a NanoString custom nCounter-TagSet and compared the expression of 68 key metabolic genes in different murine models of invasive pulmonary aspergillosis, at 3 time-points, and under a variety of conditions.

The complex interaction between circadian rhythms and physiological functions is essential for maintaining human health. At the heart of this interaction lies the PERIOD proteins (PERs), pivotal to the circadian clock, influencing the timing of physiological and behavioral processes and impacting oxidative stress, immune functionality, and tumorigenesis. PER1 orchestrates the cooperation of the enzyme GPX1, modulating mitochondrial dynamics in sync with daily rhythms and oxidative stress, thus regulating the mechanisms managing energy substrates.
