Protected edit request on 5 December 2019[edit]

Change: under ”Mechanism of action”; include: It has been reported off-target effects of Dz13, not related to the inactivation of c-Jun [1][2][3]

Change: under “References”; include: [1] [2] [3]

Change: under “Investigations”, before the sentence “A series of investigations”; include: Six of Khachigian's research articles have been retracted and one corrected due to unresolved concerns over missing or manipulated data. [4] [5] [6]

Change: under “Investigations”, end of paragraph; include: “This conclusion has been challenged”.[7]

Reason for change: important to include more information from another point of view. Moroks (talk) 13:28, 5 December 2019 (UTC)[reply]

 Not done for now: please establish a consensus for this alteration before using the {{edit protected}} template. — Martin (MSGJ · talk) 22:33, 5 December 2019 (UTC)[reply]

Change: Under the headline “Mechanism of action”; include as the third paragraph:

Oligonucleotides such as Dz13 may be used with carriers such as cationic polymers for improved cellular delivery and efficacy.[1] Dz13 in such polymers inhibits tumor cell proliferation and migration by suppressing levels of c-Jun and MMPs,[2] reduces H1N1 and H7N2 viral replication and increases survival of mice infected with influenza A[3] and suppresses c-Jun and solid tumor growth in biomimetic nanoballs.[4] Dz13 has also been used in dermal drug delivery systems for enhanced skin penetration of DNAzyme.[5]

Under “References”; include:

[1] [2] [3] [4] [5]

Reason for change:

Provides critical information on Dz13 from different laboratories.


Moroks suggested on 5 December 2019 to “Change: under “Investigations”, before the sentence “A series of investigations”; include: Six of Khachigian's research articles have been retracted and one corrected due to unresolved concerns over missing or manipulated data. [4] [5] [6]”. This sentence should not be included since it is neither relevant nor factual as explained below.

Reasons for not inserting Moroks’ proposed sentence:

(a) Only one (1) of the 6 retracted articles relates to Dz13.[6] This is the “2010 paper” already noted in the existing first sentence “In 2013, trials of Dz13 …”. It is mischievous to refer to the 5 other papers on this page as these do not relate to Dz13; (b) None of the publisher retraction notices for any of these 6 research articles refer to manipulated data;[7] (c) Although data manipulation was initially alleged, the independent expert panels investigating this article found genuine error or honest oversight, not deliberate or intentional conduct.[8] [9]
