Purpose: The project is aimed to detect anti-mitotic spindle apparatus antibody (MSA) and anti-centromere antibody (ACA) and explore the clinical value for the diagnosis of small cell lung cancer (SCLC), providing clinical evidence for molecular studies of SCLC.
Methods: 93 SCLC patients, 208 patients with other cancers and 50 healthy controls were enrolled in this study. MSA antibodies were detected by enzyme linked immunosorbent assay (ELISA). MSA, ACA and anti nuclear antibodies (ANA) were examined by indirect immuno-fluorescence (IIF). And the results were retrospectively analyzed.
Results: ① the positivity for MSA and ACA by IIF assay was respectively 36.56% and 30.11% in SCLC group, higher than in other tumor groups (P<0.01), ② in correlative analysis, the RR (Relative Ratio) value between MSA and SCLC was as high as 12.93, 12.74, and the RR value of ACA and ANA with SCLC was respectively 4.31 and 3.48. ③ the area under ROC (Receiver operating characteristic) curve (AUC) of MSA detection for SCLC was 0.778, with medium diagnostic value.
Conclusion: MSA and ACA might serve as a new marker for SCLC because of its high detection rate. These two markers may participate in the occurrence and development of SCLC, resulting from the highly strong risk. So, the study have some application value for early detection, clinical diagnosis and potential treatments of SCLC.

Targeting chromosomally unstable tumors with a selective KIF18A inhibitor.
Nat Commun

Chromosome instability is a prevalent vulnerability of cancer cells that has yet to be fully exploited therapeutically. To identify genes uniquely essential to chromosomally unstable cells, we mined the Cancer Dependency Map for genes essential in tumor cells with high levels of copy number aberrations. We identify and validate KIF18A, a mitotic kinesin, as a vulnerability of chromosomally unstable cancer cells.

The Canadian prairie ecosystem is subjected to abiotic and biotic conditions that induce plants to produce secondary metabolites that affect mammalian physiology. Extracts prepared from certain plant species native to Canadian prairie and montane cordillera ecosystems have previously been shown to have anti-mitotic activity on human cancer cell lines. In this study, we investigated the glacier lily, Erythronium grandiflorum (Liliaceae), in which the species was the most phylogenetically distant from Asteraceae and had anti-mitotic activity.

Anti-mitotic drugs are clinically used as anti-cancer treatments. Polo-like kinase 1 (PLK1) is a promising target against cancer cell division due to its importance in the whole process of mitosis, and thus PLK1-targeting agents have been developed in the last few decades. Clinical trial studies show that several PLK1 inhibitors are generally well-tolerated.

Mechanical force generation plays an essential role in many cellular functions, including mitosis. Actomyosin contractile forces mediate changes in cell shape in mitosis and are implicated in mitotic spindle integrity via cortical tension. An unbiased screen of 150 small molecules that impact actin organization and 32 anti-mitotic drugs identified two molecular targets, Rho kinase (ROCK) and tropomyosin 3.

Pharmacophore hybridization is an attractive strategy to identify new leads against multifactorial diseases such as cancer. Based on literature analysis of compounds possessing 'vicinal diaryl' fragment in their structure, we considered Discoipyrroles A-D and Combretastatin A-4 (CA-4) as possible components in hybrid design. Discoipyrrole C (Dis C) and CA-4 were used as reference compounds in these studies and their hybrids, in the form of 4,5-diaryl-1H-pyrrol-3(2H)-ones, were synthesized from suitable amino acid precursors though their ynone intermediates.
