Current Proteomics - Volume 20, Issue 2, 2023

Dry Blood Spots (DBS) have been used in combination with liquid chromatography-mass spectrometry for targeted proteomics to identify sensitive and specific novel biomarkers. DBS presents several advantages over other traditional blood sampling methods. This review discusses the past, present and future of the technology, focusing on studies with clinical and population relevance. Arguments for and against DBS are pre Read More

Background: Chlamydiasis is a widespread bacterial infection in the world. Serological tests are expensive, and in addition, intrinsic antigens can cause cross-reactions and make the diagnosis process difficult. Multi-epitope protein antigens are novel and potential diagnostic markers that have the capability of more accurate and cheaper diagnosis. Therefore, in this study, the main goal is to design a new protein vaccine, includi Read More

Background: Cold exposure can induce inflammation-related injury in lung tissue, but the exact mechanism is still unclear.Objective: The study aimed to clarify the proteomic characteristics of lung tissue under cold exposure.Methods: Forty mice were randomly equally divided into a control group and a model group. The model group was exposed to - 20°C for two weeks (4 hours per day), while the control group was maintai Read More

Background: Ricin is the most toxic protein known. It is part of the ribosome-inactivating proteins, RIPs, type 2, which has generated importance in his research; it is possible to detoxify this protein with phenolic compounds; however, it is essential to understand how this detoxification occurs. To analyze using electrophoresis, UV-visible spectroscopy, and high-performance liquid chromatography (HPLC) the protein ricin with the fl Read More

Introduction: Ovarian cancer is a common gynecological malignancy. It is one of the leading causes of death among women worldwide. The incidence of ovarian cancer ranks third, and mortality is the first among gynecological malignant tumors. CCL2 (Chemokine C-C motif Ligand 2) is associated with the progression of a variety of tumors, including ovarian cancer. However, the mechanism of CCL2 in A2780 cell growth Read More

Background: Neonate lung injury is a common phenomenon after perinatal asphyxia.Objective: To evaluate proteomic profiles of exosomes isolated from lung injury offspring serum after perinatal asphyxia.Methods: Serum samples were collected at 12 h, 24 h, and 72 h after birth in neonates with perinatal asphyxia-induced lung injury. Exosomes were isolated, and the concentration and size distribution were assessed. The exo Read More
