| 1 | In vivo flow cytometry reveals a circadian rhythm of circulating tumor cells显示文摘Circulating tumor cells(CTCs)is an established biomarker of cancer metastasis.The circulation dynamics of CTCs are important for understanding the mechanisms underlying tumor cell dissemination.Although studies have revealed that the circadian rhythm may disrupt the growth of tumors,it is generally unclear whether the circadian rhythm controls the release of CTCs.In clinical examinations,the current in vitro methods for detecting CTCs in blood samples are based on a fundamental assumption that CTC counts in the peripheral blood do not change significantly over time,which is being challenged by recent studies.Since it is not practical to draw blood from patients repeatedly,a feasible strategy to investigate the circadian rhythm of CTCs is to monitor them by in vivo detection methods.Fluoresce nee in vivo flow cytometry(IVFC)is a powerful optical technique that is able to detect fluoresce nt circulating cells directly in living animals in a noninvasive manner over a long period of time.In this study,we applied fluorescence IVFC to monitor CTCs noninvasively in an orthotopic mouse model of human prostate cancer.We observed that CTCs exhibited stochastic bursts over cancer progression.The probability of the bursting activity was higher at early stages than at late stages.We longitudinally monitored CTCs over a 24-h period,and our results revealed striking daily oscillations in CTC counts that peaked at the onset of the night(active phase for rodents),suggesting that the release of CTCs might be regulated by the circadian rhythm. | Xi Zhu Yuanzhen Suo Yuting Fu Fuli Zhang Nan Ding Kai Pang Chengying Xie Xiaofu Weng Meilu Tian Hao He Xunbin Wei | 2021 | Light(Science & Applications)2021，10，6： | 6 |
| 2 | Reply to Comment on “In vivo flow cytometry reveals a circadian rhythm of circulating tumor cells”显示文摘Dear Editor,We thank Niedre et al.for their correspondence regarding our recent paper1.They proposed a point that the temporal distribution of circulating tumor cells(CTCs)monitored by diffuse in vivo flow cytometry in a multiple myeloma mouse model in their previous work2 might be different from our results.Niedre et al.claimed that CTC detection statistics deviated from Poisson but did not found circadian variations in CTC numbers in a multiple myeloma mouse model.They also cite another literature by Juratli.et al.3,in which the authors reported that CTC numbers did not always correlate with tumor size during cancer progression.However,by establishing an orthotopic mouse model of prostate cancer and utilizing the technology in vivo flow cytometry(IVFC),we found CTCs exhibited bursting activity and daily oscillation in an orthotopic model of prostate cancer. | Xi Zhu Yuanzhen Suo Yuting Fu Fuli Zhang Nan Ding Kai Pang Chengying Xie Xiaofu Weng Meilu Tian Hao He Xunbin Wei | 2021 | Light(Science & Applications)2021，10，10： | 2 |
