In silico identification of drug targets and vaccine candidates against Bartonella quintana: a subtractive proteomics approach

BACKGROUND The availability of genes and protein sequences for parasites has provided valuable information for drug target identification and vaccine development. One such parasite is Bartonella quintana, a Gram-negative, intracellular pathogen that causes bartonellosis in mammalian hosts. OBJECTIVE Despite progress in understanding its pathogenesis, limited knowledge exists about the virulence factors and regulatory mechanisms specific to B. quintana. METHODS AND FINDINGS To explore these aspects, we have adopted a subtractive proteomics approach to analyse the proteome of B. quintana. By subtractive proteins between the host and parasite proteome, a set of proteins that are likely unique to the parasite but absent in the host were identified. This analysis revealed that out of the 1197 protein sequences of the parasite, 660 proteins are non-homologous to the human host. Further analysis using the Database of Essential Genes predicted 159 essential proteins, with 28 of these being unique to the pathogen and predicted as potential putative targets. Subcellular localisation of the predicted targets revealed 13 cytoplasmic, eight membranes, one periplasmic, and multiple location proteins. The three-dimensional structure and B cell epitopes of the six membrane antigenic protein were predicted. Four B cell epitopes in KdtA and mraY proteins, three in lpxB and BQ09550, whereas the ftsl and yidC proteins were located with eleven and six B cell epitopes, respectively. MAINS CONCLUSIONS This insight prioritises such proteins as novel putative targets for further investigations on their potential as drug and vaccine candidates.

Risk Factors of Depression Screened by Two-Sample Mendelian Randomization Analysis: A Systematic Review / 生物医学与环境科学（英文）

OBJECTIVE@#This study explored the potentially modifiable factors for depression and major depressive disorder (MDD) from the MR-Base database and further evaluated the associations between drug targets with MDD.@*METHODS@#We analyzed two-sample of Mendelian randomization (2SMR) using genetic variant depression ( n = 113,154) and MDD ( n = 208,811) from Genome-Wide Association Studies (GWAS). Separate calculations were performed with modifiable risk factors from MR-Base for 1,001 genomes. The MR analysis was performed by screening drug targets with MDD in the DrugBank database to explore the therapeutic targets for MDD. Inverse variance weighted (IVW), fixed-effect inverse variance weighted (FE-IVW), MR-Egger, weighted median, and weighted mode were used for complementary calculation.@*RESULTS@#The potential causal relationship between modifiable risk factors and depression contained 459 results for depression and 424 for MDD. Also, the associations between drug targets and MDD showed that SLC6A4, GRIN2A, GRIN2C, SCN10A, and IL1B expression are associated with an increased risk of depression. In contrast, ADRB1, CHRNA3, HTR3A, GSTP1, and GABRG2 genes are candidate protective factors against depression.@*CONCLUSION@#This study identified the risk factors causally associated with depression and MDD, and estimated 10 drug targets with significant impact on MDD, providing essential information for formulating strategies to prevent and treat depression.

Liver Injury Caused by Psoraleae Fructus： A Review / 中国实验方剂学杂志

Psoraleae Fructus （PF） is a non-toxic Chinese herbal medicine， while the liver injury caused by PF has aroused wide concern in recent years. At present， animal experiments and in vitro studies have been carried out to explore the mechanism， targets， and toxic components of PF in inducing liver injury， which， however， have differences compared with the actual conditions in clinical practice， and there are still some potential hepatotoxic components and targets of PF that have not been discovered. With the continuous progress in systems biology， establishing the drug-induced liver injury model and the liver injury prediction model based on network toxicology can reduce the cost of animal experiments， improve the toxicity prediction efficiency， and provide new tools for predicting toxic components and targets. To systematically explain the characteristics of liver injury in the application of PF and explore the potential hepatotoxic components and targets of PF， we reviewed the related articles published by China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， and PubMed from 1962 to 2021 and analyzed the characteristics and influencing factors of liver injury caused by PF in the patients. Furthermore， we summarized the chemical components of PF and the components entering blood. By reviewing the mechanism， targets， and components of PF in inducing liver injury that were discovered by in vivo and in vitro experiments， we summarized the known compounds in PF that may cause liver injury. Finally， the current methods for building the prediction model of PF-induced liver injury were summarized， and the predicted toxic components and targets were introduced. The possible factors of PF in causing liver injury were explained from three aspects： clinical characteristics， preclinical studies， and computer-assisted network prediction， which provide a reference for predicting the risk of PF-induced liver injury.

Research Progress of Antibody-drug Conjugates in Small-cell Lung Cancer / 肿瘤防治研究

Antibody-drug conjugates (ADCs) are novel drugs consisting of monoclonal antibodies targeting tumor-specific or tumor-associated antigens coupled with different numbers of payloads via linkers. ADCs have shown promising clinical benefits in the treatment of a variety of malignancies. Small-cell lung cancer (SCLC) is a hypo-differentiated neuroendocrine tumor with an extremely high degree of malignancy. Although SCLC is sensitive to radiotherapy and chemotherapy, it has a poor prognosis due to characteristics such as early susceptibility to metastasis and recurrence. Progress in the treatment of SCLC is very limited, and more durable and effective therapies should be developed to improve prognosis. However, the progress of SCLC-related therapeutic agents has been limited by the lack of specific molecular targets. This article reviews the basic principles and mechanisms of ADCs, highlights the research progress of relevant drugs against some targets in SCLC, and summarizes new targets that may be developed as targeted drugs.

Research progress of effect of gut microbiota on non-small cell lung cancer / 中国胸心血管外科临床杂志

@#The human gut microbiota regulates many host pathophysiological processes including metabolic, inflammatory, immune and cellular responses. In recent years, the incidence and mortality of lung cancer have increased rapidly, which is one of the biggest challenges in the field of cancer treatment today, especially in non-small cell lung cancer. Animal models and clinical studies have found that the gut microbiota of non-small cell lung cancer patients is significantly changed compared with the healthy people. The gut microbiota and metabolites can not only play a pro-cancer or tumor suppressor role by regulating immune, inflammatory responses and so on, but also be related with radiotherapy and chemotherapy of non-small cell lung cancer and the resistance of immunotherapy. Therefore, gut microbiota and related metabolites can be both potential markers for early diagnosis and prognosis in patients with non-small cell lung cancer and novel therapeutic targets for targeted drugs. This study will review the latest research progress of effect of gut microbiota on non-small cell lung cancer, and provide a new diagnosis and treatment ideas for non-small cell lung cancer.

The role of retinal signaling molecules in the occurrence and progression of myopia / 中华眼底病杂志

With the surged prevalence of myopia, the pathogenic mechanism underlying myopia has attracted attention. At present, it is generally believed in the flied that the reduced blood perfusion in the choroid is crucial for myopigenesis. Then, in the process of myopigenesis, how are the blurred visual signals transmitted to the choroidal blood vessels through the retina and retinal pigment epithelium, leading to the reduced choroidal blood perfusion. The cellular and molecular mechanisms underpinning this process remain elusive. In recent years, the theory of scleral hypoxia has attracted much attention. Popular signaling molecules in current research include dopamine, epidermal growth factor, retinoic acid, cholinergic molecules and adenosine, etc. These factors are likely to participate in signal transduction in retina and RPE, thus causing changes in choroidal blood flow and affecting the occurrence and development of myopia. Therefore, these signaling factors and their downstream pathways may provide new ideas for the prevention and control of myopia targets.

The Structure and Function of the Bunyavirus Nucleoprotein / 中国生物化学与分子生物学报

Bunyavirus is widely distributed, highly contagious, and has a high fatality rate. It is a negative- strand RNA virus that has a major impact on public health around the world. The development of vaccines and the search for drugs are the key to prevent bunyavirus infection. The nucleoprotein (NP) of viruses is necessary for the synthesis of viral RNA, which combines with viral RNA to form the nucleocapsid, participates in viral assembly and RNA transcription, and plays an important role in viral proliferation. In addition, NP also has B cell and T cell epitopes, which can induce cellular and humoral immunity, so NP is an ideal target for vaccine design and drug development. Given its abundance and specificity, NP is also commonly used in the detection of viral diseases. More and more bunyavirus NP structures and structures of NP-RNA complexes have been resolved. Researchers have discovered two important antiviral targets through these structures, the terminal arm and the RNA binding cleft. This paper reviews the function and three-dimensional structure of the bunyavirus NP and the research progress of NP as an antiviral target, in order to provide a theoretical basis for the prevention and treatment of the bunyavirus disease.

Biological Implication of Chimeric RNAs in Cancer / 中国生物化学与分子生物学报

Chimeric RNA is a fusion transcript composed of exons from two or more different genes and generated by chromosome rearrangement or RNA splicing. Chimeric RNAs have the potential to encode novel proteins or function as non-coding RNAs. Chimeric RNAs were ubiquitously expressed across different cancers and normal tissues. To date, mechanistic and functional studies of chimeric RNAs still remain unclear. Precise definition and terminology in the research field of chimeric RNA will be discussed in this review. The formation, classification and clinical significance of chimeric RNAs in cancer progression will be summarized. Previous studies showed that products of chimeric RNAs may play important roles in regulating cell proliferation, motility, invasion and apoptosis through encoded fusion proteins or long non-coding chimeric RNAs. In cancer, chimeric RNA and its encoded specific protein or non-coding RNA can regulate tumorigenesis by changing cell phenotypes or directly affecting gene expression or regulatory pathways, which have the potential to be important diagnostic biomarkers and therapeutic targets. In recent years, more and more cancer-specific chimeric RNAs have been discovered from multiple types of cancers and used as therapeutic targets due to their vital roles in disease prognosis. Therefore, this review will focus on the functions and applications of chimeric RNAs in different tumors, which can shed a light on cancer diagnosis and therapeutics from the new perspective.
