Abstract
BACKGROUND Clostridium piliforme (causative agent of Tyzzer disease) infects various animals, including primates, and hence a threat to animal and human health worldwide. At present, it is detected using traditional methods, such as path morphology, polymerase chain reaction and enzyme-linked immunosorbent assay. Therefore, it is necessary to develop convenient, efficient visual molecular biological methods for detecting C. piliforme. OBJECTIVES To establish a method with good specificity, high sensitivity and simple operation for the detection of C. piliforme. METHODS In this study, we designed internal and external primers based on the conserved 23S rRNA region of C. piliforme to develop a biotin-labelled diarrhoea-suffered loop-mediated isothermal amplification (LAMP) system for detecting of C. piliforme and assessed the specificity, sensitivity and repeatability of the LAMP system. RESULTS The LAMP system did not exhibit cross-reactivity with 24 other common pathogenic species, indicating that it had good specificity. The minimum concentration of sensitivity was 1 × 10-7 ng/μL. Mouse models (Meriones unguiculatus) of Tyzzer disease were established and a LAMP-lateral flow dipstick (LAMP-LFD) was developed for detecting C. piliforme. The detection rate of C. piliforme was 5.08% in clean-grade animals and 9.96% in specific-pathogen-free-grade animals from Jiangsu, Zhejiang and Shanghai. In addition, the detection rates of C. piliforme were 10.1%, 8.6% and 20%, in animals from Hangzhou, Wenzhou and Shaoxing, respectively. The detection rate of C. piliforme was higher in experimental animals used in schools than in those used in companies and research institutes. CONCLUSIONS The LAMP-LFD method established in this study can be used to detect C. piliforme in animals handled in laboratory facilities of universities, pharmaceutical enterprises and research and development institutions.

BNIP3 as a potential biomarker for the identification of prognosis and diagnosis in solid tumours. Mol Cancer 2023; 22:143.

Abstract
BACKGROUND Traditional radiotherapy and chemotherapy have been intensively studied for their role in the treatment of tumours. However, these therapies often cause side effects for patients, which calls for the development of novel treatment options for tumours. B-cell lymphoma-2 (Bcl-2)/adenovirus E1B 19 kDa-interacting protein 3 (BNIP3) reportedly apoptosis-inducing effects in tumour cells and is associated with the progression and treatment of multiple tumours. Nevertheless, little is known about its potential role in tumour diagnosis and targeted therapy. FINDINGS The results of the study demonstrated that the interaction of BNIP3 with HDAC1 may affect the progression of breast invasive cancer (BRCA), sarcoma (SARC), kidney renal clear cell carcinoma (KIRC), and low-grade glioma (LGG). BNIP3 seemed to exert its effects in BRCA and SARC primarily through gene silencing and integrator complex, and in KIRC and LGG, mainly by affecting olfactory function, suggesting that targeted therapy can be developed based on the above signalling pathway and downstream molecules. INTERPRETATION BNIP3 has emerged as a promising therapeutic and diagnostic target for BRCA, SARC, KIRC, and LGG, providing new insights into tumour molecular therapies in the clinic.
