Muscle stem cells can drive cancer that arises in Duchenne muscular dystrophy
People with Duchenne muscular dystrophy (DMD) can develop an otherwise-rare muscle cancer, called rhabdomyosarcoma, due to the muscle cells' continuous work to rebuild the damaged tissue. However, little is known about how the cancer arises, hindering development of a treatment or test that could predict cancer risk.
Those suffering from cancer, heart conditions, strokes, diabetes and lung disease are among the worst affected by delays to their diagnosis and care, a survey of senior doctors reveals.
The objective of this study was to report the incidence of alopecia arising in patients treated with vismodegib, assessing its characteristics, grade of severity, and time of onset.Skin Appendage Disord
CONCLUSIONS: Surprisingly, the DCR registered fewer patients in 2013-2014 than the DLCR, even though they employ the same primary data source. The agreement between the DCR and the DLCR was 87%; this may be increased to 95% if patients who seemed to meet the inclusion criteria of the other register were also included. The discrepancies found were mainly due to different definitions of dates of diagnosis, registrations probably missed by the algorithms and possible registration errors. Discrepancies resulted in a significant difference in MRR, but not in 1y-RS. FUNDING: none. TRIAL REGISTRATION: not relevant. PM...
CONCLUSIONS: Most women did not experience any improvement in their symptoms over time, and no association was found between lack of symptom improvement and believing that the HPV vaccine was causing the symptoms. FUNDING: funded by the Danish Cancer Society. TRIAL REGISTRATION: not relevant. PMID: 32741432 [PubMed - in process]

We report that even before tumor formation, MuSCs exhibit increased self-renewal and an expression signature associated with RMSs. These cells can form tumorspheres in vitro and give rise to RMSs in vivo. Finally, we show that the inflammatory genes Ccl11 and Rgs5 are involved in RMS growth. Together, our results show that DMD severity drives MuSC-mediated RMS development.Graphical Abstract
Dystrophin inactivation, responsible for Duchenne muscular dystrophy (DMD), is recently implicated as an anti-tumor suppressor factor in cancers with myogenic characteristics. Rhabdomyosarcoma (RMS), a mesodermal cancer, shows myogenic features and occurs at a higher frequency in mdx mouse, a DMD model mouse. In humans, as the clinical management of DMD advances to increase the life expectancy of patients, a subsequent issue is anticipated to be that of addressing other complications such as RMS.
The DMD gene encoding dystrophin is mutated in Duchenne muscular dystrophy, a fatal progressive muscle wasting disease. DMD has also been shown to act as a tumor suppressor gene. Rhabdomyosarcoma (RMS) is a mesod...
