Article Abstract
Serine proteases are multifunctional and versatile venom components found in viper snakes, including the species, a widely distributed genus notorious for causing the highest number of snakebites across Latin America. These enzymes, representing a significant fraction of venom proteomes, exhibit a wide range of biological activities that influence blood coagulation, fibrinolysis, and inflammation. This review provides a comprehensive overview of serine proteases, with a particular focus on those found in the venom of Brazilian snakes. The discussion begins with a summary of snake species found in Brazil and their medical relevance. Specifically addressing the genus, this review explores the distribution of these species across Brazilian territory and their associated medical importance. Subsequently, the article investigates the biochemistry of venoms and the clinical manifestations induced by envenomation. Finally, it offers an in-depth discussion on the serine proteases, highlighting their biochemical properties, mechanisms of action, and potential therapeutic applications. Furthermore, this review provides an in-depth exploration of the diverse serine proteases found in venoms and their functional significance, from thrombin-like effects to potent fibrinogenolytic actions, which determine the clinical manifestations of envenomation. This review delves into the evolutionary adaptations and biochemical diversity of serine proteases in venoms, emphasizing their critical roles in venom functionality and the resulting pathophysiological effects. Additionally, it opens new avenues for utilizing these enzymes in biomedical applications, underscoring their potential beyond toxinology.

Current antithrombotic therapies face dual constraints of bleeding complications and monitoring requirements. Although natural hirudin provides targeted thrombin inhibition, its clinical adoption is hindered by sourcing limitations. This study developed a recombinant hirudin variant HMg (rHMg) with enhanced anticoagulant activity through genetic engineering and established cost-effective large-scale production methods.

Background: Targeted bottom-up proteomics is of great interest for the straightforward, accurate, and sensitive measurement of specific protein biomarkers from surrogate peptide fragments. However, this approach typically relies on off-line enzymatic digestion with trypsin, a time-consuming step that may be inadequate for covering certain sequence regions containing important post-translational modifications (PTMs).
Results: In this study, we present an in-line enzymatic digestion strategy for the targeted bottom-up analysis of α-synuclein (α-syn), which is a protein biomarker of Parkinson's disease (PD).

Osteoarthritis (OA) is the most prevalent and disabling joint disease, while adipose-derived stem cells (ASCs) have emerged as a promising therapeutic option in pre-clinical studies. However, the therapeutic efficacy of ASCs may be influenced by the source of these cells, especially in obese patients. This study compared the effects of intra-articular injections of ASCs from wild-type (WT) and ob/ob (OB) mice.

Prostate cancer is a common malignant tumor of the male urinary system. Early diagnosis is very important to improve the survival rate and quality of life of patients. In this paper, the screening methods for early prostate cancer will be systematically reviewed, covering serum prostate-specific antigen (PSA) related testing, non-PSA related testing, as well as emerging genetic and genetic testing technologies.
