In America, of course, we don’t have that kind of state coercion. There are currently no laws that shape what academics or journalists can say; there is no government censor, no ruling-party censor. But fear of the internet mob, the office mob, or the peer-group mob is producing some similar outcomes. How many American manuscripts now remain in desk drawers—or unwritten altogether—because their authors fear a similarly arbitrary judgment? How much intellectual life is now stifled because of fear of what a poorly worded comment would look like if taken out of context and spread on Twitter?
Fear of cancel culture and social repercussions prevents people from speaking and communicating as they might otherwise.
Compare this with the right to reach, particularly for those without editors, filtering, or having built a platform and understanding how to use it responsibly.

Facebook could shift the burden of proof toward people and communities to demonstrate that they’re good actors—and treat reach as a privilege, not a right.
Nice to see someone else essentially saying something along the lines that "free speech" is not the same as "free reach".
Traditional journalism has always had thousands of gatekeepers who filtered and weighed who got the privilege of reach. Now anyone with an angry, vile, or upsetting message can get it for free. This is one of the worst parts of what Facebook allows.

In accordance with the ability of mutant SPOP to repress the function of endogenous wild type SPOP in a dominant negative manner, the over-expression of mutant SPOP (SPOP-Y87C, -F102C, -W131G, -F133S) phenocopied the effect of SPOP knockdown on ERG mediated invasion in PC3 cells.
ERG inhibits Neoplasm Invasiveness.
-
In line with these findings, gene ontology analysis of AR-ERG co-bound gene signature in VCaP cells indicated that the most striking transcriptional changes were linked to cellular differentiation and cell cycle arrest that are directly induced by DHT and repressed by ERG (e.g., HOXA genes, CDKN1A and p21, Fig.
ERG inhibits cell differentiation.

-
Similarly, knockdown of SPOP in VCaP cells reduced cell growth in 3D cell culture and impaired ERG mediated gene transcription.
ERG inhibits transcription, DNA-templated.
-
The oncogenic effect was paralleled by an increase in the expression of the oncogenic transcription factors MYC and HOXB13 and a decrease in the cell cycle inhibitor p21 as seen in an organoid line derived from Spop F133V -mutant transgenic mice 13.
CDKN1A inhibits cell cycle.

ZMYND11 induces AR signaling pathway and represses ERG activity.
-
In accordance with the ability of mutant SPOP to repress the function of endogenous wild type SPOP in a dominant negative manner, the over-expression of mutant SPOP (SPOP-Y87C, -F102C, -W131G, -F133S) phenocopied the effect of SPOP knockdown on ERG mediated invasion in PC3 cells.
SPOP inhibits Neoplasm Invasiveness.
-
We found two degron sequences that were required for efficient SPOP mediated ubiquitylation and protein degradation.
SPOP inhibits proteolysis.
-
Moreover, knockdown of ERG reduced SPOP protein levels in VCaP cells, while forced expression of a DeltaERG led to the upregulation of SPOP mRNA and protein levels in PC3 cells.
-
Thus, we wondered if ERG itself may directly upregulate SPOP transcription to support its own oncogenic activity.
-
Indeed, knockdown of TRIM24 by two short-hairpin RNAs partially reverted the growth inhibition mediated by mutant-SPOP in VCaP cells and reduced AR signaling, while over-expression of AR was sufficient to decrease cellular growth.
AR activates cell growth.
-
In agreement with the established repressive function of ZMYND11 on ERG, we found that over-expression of HA-ZMNYD11-DM2 was sufficient to repress ERG induced invasion and established target genes in PC3 cells.
ERG activates Neoplasm Invasiveness.
-
We then asked if the elevated SPOP levels in the context of forced DeltaERG expression have a functional impact on the oncogenic activity of DeltaERG in the androgen independent PC3 cells, in which ERG promotes tumor cell invasion 31.
ERG activates Neoplasm Invasiveness.
-
ZMYND11 induces AR signaling pathway and represses ERG activity.
-
We postulated that ZMYND11 upregulation could contribute to the synthetic sick relationship by repressing the ERG oncogene 's transcriptional activity or enhancing AR signaling.
-
Mutant SPOP induced androgen receptor signaling antagonizes ERG activity.
-
Conversely, we assessed the consequence of ERG overexpression in LNCaP cells under low DHT levels where mutant SPOP triggers AR signaling and tumor growth XREF_BIBR, XREF_BIBR.
-
Taken together, the data imply a mutual incompatibility of mutant SPOP induced AR signaling and the function of the ERG oncogene.
