how about the toxicity from the ARMMs? e.g. delivery of WT p53 into mice may cause apoptosis in cells in normal tissues.

01:16:17
What would you predict to happen when you have mixtures of metals - arsenic + something else (e.g., Mn or Chromium)?

01:16:42
Would you expect same pattern as arsenic?

01:17:30
Great -thanks

01:17:37
Are other non-coding RNAs being investigated by your group as part of the research in EVs?

01:18:12
have you examined what sort of EVs are favored for release following metal exposures (exosomes, ARMMs, microvesicles)?

01:18:12
How do exosomes contribute or not to your studies

01:19:35
do ARMM EVs differ from exosomes mainly based on the presence of the ARRCD protein or are there other different cargo that stand out between these two types of EVs?

01:21:09
How are ARMMs primarily incorporated by recipient cells? Is there an activation of clathrin/calveolin-mediated endocytosis or are then incorporated by plasma membrane fusion?

01:21:30
Have you used any specific antibody-based column purification strategies to differentiate exosomes from ARMMs

01:23:10
How is the functional association or connection between ARRCD 1 and ARRCD1 may like? Since they seem like to play kind of specific roles in regulating the process of virus budding ?

01:24:00
Once ARMMs are internalized, are they targeted to lysosome or endosome of the recipient cells

01:25:58
Sorry ARRCD3

01:27:28
I saw that overexpression of ARRDC1 increases EV release by cells. Is there an increase in ARRDC1 in cells following metal exposure?

01:28:21
Outstanding work and look forward to learning more about the ARMMs, exosomes in metals toxicology in the future. Thank you

01:30:21
Thank you!
