Digital governance must not marginalize smaller states Expert comment LToremark 19 May 2021

For effective and inclusive digital governance, multi-stakeholderism must raise its game.

Last month, the G7 announced it is to work towards a trusted, values-driven digital ecosystem. While this is commendable, the G7 must recognize that key international digital governance decisions should involve all states whose populations will be affected. Not doing so is to deny the legitimate interests of those populations and may cause a lack of trust in international digital governance that embeds longer-term instability.

While a multi-stakeholder approach to digital governance is important, it must be structured in a way that allows for meaningful representation of states’ interests and ensures their representatives have the opportunity and capacity to take part. As the internet becomes fundamental to life in every country of the world, international digital governance is increasingly important to all governments and excluding some states’ perspectives may engender wider risks to international security and governance.

The ‘glitter ball’ of digital governance

International digital governance is playing catch-up with the digital sphere it needs to govern. Its starting point is a ‘glitter ball’ of governance initiatives: a large number of complex facets with overlapping impacts – and an almost impenetrable core. Governance initiatives (see infographic) include governance of the internet itself and its uses, international cybersecurity, international human rights, data management, as well as the impact of digital developments in areas such as armed conflict, trade and health.

Many of the bodies involved – such as the Internet Governance Forum, the Internet Corporation for Assigned Names and Numbers (ICANN) and technical standards bodies – include a wide range of stakeholders, yet there is no one accessible, central body. Furthermore, certain key issues, such as the role and responsibilities of tech platforms, are barely touched upon by international governance mechanisms. There is also currently only a limited role for traditional UN multilateral decision-making, a process which builds in a role for smaller states.

The sheer number of forums involved, each with a different set of working methods and rules on participation, makes it difficult to fully grasp what digital governance looks like as a whole. The UN secretary-general’s High-level Panel on Digital Cooperation recognized the complexity of digital cooperation arrangements and the barriers to inclusion facing small and developing countries as well as under-represented groups. In response, the June 2020 UN Roadmap on Digital Cooperation accepts the need to streamline digital governance while ensuring marginalized voices are heard.

The UN is considering potential models for future governance, each of which would – reassuringly – involve multi-stakeholder participation, dedicated funds to boost participation, consolidation of discussions currently split between different forums and a minor coordinating role for the UN.  

Building in roles for smaller states

As the UN designs new digital governance architecture, it is particularly important to build in roles for small and medium states. Core constituencies affected by decisions should be at the centre and governments – as guardians of public interest – should have a key say in the decision-making process. The distrust generated by built-in power imbalances needs to be addressed, as does the dominance of voices from the Global North in bodies such as ICANN.   

There has been some progress made to increase participation. For example, the Freedom Online Coalition includes a number of developing countries and the 2020 Internet Governance Forum included input from 175 states.

However, participation is not only a matter of having a seat at the table. As discussed at the March 2021 UN Open-ended Working Group on ICTs in the context of international security, capacity-building is vital. The group’s conclusions include the suggested development of a global cyber capacity-building agenda with information sharing and norms guidance under the auspices of the UN. Representatives of small and medium states need a roadmap to understand in which forums they can defend and pursue their interests, and the financial help to do so if necessary.

Managing multi-stakeholder participation

A multi-stakeholder approach has been fundamental to digital governance from the start and has played a vital role in helping to secure the openness and universality of the internet. This approach is rightly seen as essential to effective governance because it introduces diverse expertise, allows the interests of all impacted sectors to be taken into account and helps ensure decisions are accepted by those affected.

However, as identified in a Chatham House report on inclusive global governance, multi-stakeholderism needs to raise its game. One of its downsides is that in the cacophony some important voices may not be heard because they lack resource or capacity to speak up. There is a perennial risk of debate and decision-making being captured by the wealthiest companies or the most powerful states. At present, small and medium states are under-represented in multi-stakeholder forums and it is important that those managing such forums seek to identify and include previously excluded voices.

Multi-stakeholderism should not come at the expense of efficiency. While it does not have to mean huge, inefficient meetings or endless discussion, it should also not mean that smaller, less well-funded voices are not heard. Instead, such processes should enable representation of appropriate interest groups, complemented by wider meetings (such as regional meetings, or sector-specific meetings) as needed. While inclusivity and transparency are key, synergies between regional and global forums can work well –  for example, some countries have adopted national versions of the Internet Governance Forum –  and so too can hybrid models such as the Freedom Online Coalition, which meets both as government members and for regular multi-stakeholder dialogue.

A multi-stakeholder approach should also not lose sight of the key role of states – and where mandated, sub-state entities – in making public policy decisions.

An important role for the UN

For 75 years, the UN has acted as a bulwark of international security and shared values, and a promoter of economic and social development. If misused, technology has the potential to undermine this bulwark, to facilitate conflict, erode rights and undermine development. The UN must encourage the harnessing of technology for society’s benefit, while leading a collective effort to guard against the risks through the retention and growth of a universal, open internet – particularly in the face of growing digital authoritarianism exacerbated by COVID-19.

The UN can also help protect against a commercial culture that threatens to trample fundamental freedoms of privacy and autonomy in its pursuit of wealth and to widen economic and social gulfs by leaving large swathes of the world behind. If the UN is to play this role effectively – and for the benefit of all its members ­– it requires the active participation of all states, large and small.

Apolipoprotein A-I (ApoA-I) of high-density lipoprotein (HDL) is essential for the transportation of cholesterol between peripheral tissues and the liver. However, specific mutations in Apolipoprotein A-I (ApoA-I) of high-density lipoprotein (HDL) are responsible for a late-onset systemic amyloidosis, the pathological accumulation of protein fibrils in tissues and organs. Carriers of these mutations do not exhibit increased cardiovascular disease risk despite displaying reduced levels of ApoA-I/ HDL-cholesterol. To explain this paradox, we show that the HDL particle profile of patients carrying either L75P or L174S ApoA-I amyloidogenic variants a higher relative abundance of the 8.4 nm vs 9.6 nm particles, and that serum from patients, as well as reconstituted 8.4 and 9.6 nm HDL particles (rHDL), possess increased capacity to catalyze cholesterol efflux from macrophages. Synchrotron radiation circular dichroism and hydrogen-deuterium exchange revealed that the variants in 8.4 nm rHDL have altered secondary structure composition and display a more flexible binding to lipids compared to their native counterpart. The reduced HDL-cholesterol levels of patients carrying ApoA-I amyloidogenic variants are thus balanced by higher proportion of small, dense HDL particles and better cholesterol efflux due to altered, region-specific protein structure dynamics.

Nonsmall cell lung cancer (NSCLC) is a leading cause of cancer-related deaths. While mutations in Kras and overexpression of Myc are commonly found in patients, the role of altered lipid metabolism in lung cancer and its interplay with oncogenic Myc is poorly understood. Here we use a transgenic mouse model of Kras-driven lung adenocarcinoma with reversible activation of Myc combined with surface analysis lipid profiling of lung tumors and transcriptomics to study the effect of Myc activity on cholesterol homeostasis. Our findings reveal that the activation of Myc leads to the accumulation of cholesteryl esters (CEs) stored in lipid droplets. Subsequent Myc deactivation leads to further increases in CEs, in contrast to tumors in which Myc was never activated. Gene expression analysis linked cholesterol transport and storage pathways to Myc activity. Our results suggest that increased Myc activity is associated with increased cholesterol influx, reduced efflux, and accumulation of CE-rich lipid droplets in lung tumors. Targeting cholesterol homeostasis is proposed as a promising avenue to explore for novel treatments of lung cancer, with diagnostic and stratification potential in human NSCLC.

Despite the crucial function of the small intestine in nutrient uptake our understanding of the molecular events underlying the digestive function is still rudimentary. Recent studies demonstrated that enterocytes do not direct the entire dietary triacylglycerol toward immediate chylomicron synthesis. Especially after high-fat challenges, parts of the resynthesized triacylglycerol are packaged into cytosolic lipid droplets for transient storage in the endothelial layer of the small intestine. The reason for this temporary storage of triacylglycerol is not completely understood. To utilize lipids from cytosolic lipid droplets for chylomicron synthesis in the endoplasmic reticulum, stored triacylglycerol has to be hydrolyzed either by cytosolic lipolysis or lipophagy. Interestingly, triacylglycerol storage and chylomicron secretion rates are unevenly distributed along the small intestine, with the proximal jejunum exhibiting the highest intermittent storage capacity. We hypothesize that correlating hydrolytic enzyme activities with the reported distribution of triacylglycerol storage and chylomicron secretion in different sections of the small intestine is a promising strategy to determine key enzymes in triacylglycerol remobilization. We employed a serine hydrolase specific activity-based labeling approach in combination with quantitative proteomics to identify and rank hydrolases based on their relative activity in 11 sections of the small intestine. Moreover, we identified several clusters of enzymes showing similar activity distribution along the small intestine. Merging our activity-based results with substrate specificity and subcellular localization known from previous studies, carboxylesterase 2e and arylacetamide deacetylase emerge as promising candidates for triacylglycerol mobilization from cytosolic lipid droplets in enterocytes.

Mallory-Denk-bodies (MDBs) are hepatic protein aggregates associated with inflammation both clinically and in MDB-inducing models. Similar protein aggregation in neurodegenerative diseases also triggers inflammation and NF-B activation. However, the precise mechanism that links protein aggregation to NF-B-activation and inflammatory response remains unclear. Herein we find that treating primary hepatocytes with MDB-inducing agents (N-methylprotoporphyrin (NMPP), protoporphyrin IX (PPIX), or Zinc-protoporphyrin IX (ZnPP)) elicited an IBα-loss with consequent NF-B activation. Four known mechanisms of IBα-loss i.e. the canonical ubiquitin-dependent proteasomal degradation (UPD), autophagic-lysosomal degradation, calpain degradation and translational inhibition, were all probed and excluded. Immunofluorescence analyses of ZnPP-treated cells coupled with 8 M urea/CHAPS-extraction revealed that this IBα-loss was due to its sequestration along with IBβ into insoluble aggregates, thereby releasing NF-B. Through affinity pulldown, proximity biotinylation by antibody recognition, and other proteomic analyses, we verified that NF-B subunit p65, which stably interacts with IBα under normal conditions, no longer binds to it upon ZnPP-treatment. Additionally, we identified 10 proteins that interact with IBα under baseline conditions, aggregate upon ZnPP-treatment, and maintain the interaction with IBα after ZnPP-treatment, either by cosequestering into insoluble aggregates or through a different mechanism. Of these 10 proteins, the nucleoporins Nup153 and Nup358/RanBP2 were identified through RNA-interference, as mediators of IBα-nuclear import. The concurrent aggregation of IBα, NUP153, and RanBP2 upon ZnPP-treatment, synergistically precluded the nuclear entry of IBα and its consequent binding and termination of NF-B activation. This novel mechanism may account for the protein aggregate-induced inflammation observed in liver diseases, thus identifying novel targets for therapeutic intervention. Because of inherent commonalities this MDB cell model is a bona fide protoporphyric model, making these findings equally relevant to the liver inflammation associated with clinical protoporphyria.

The origin recognition complex (ORC), composed of six subunits, ORC1–6, binds to origins of replication as a ring-shaped heterohexameric ATPase that is believed to be essential to recruit and load MCM2–7, the minichromosome maintenance protein complex, around DNA and initiate DNA replication. We previously reported the creation of viable cancer cell lines that lacked detectable ORC1 or ORC2 protein without a reduction in the number of origins firing. Here, using CRISPR-Cas9–mediated mutations, we report that human HCT116 colon cancer cells also survive when ORC5 protein expression is abolished via a mutation in the initiator ATG of the ORC5 gene. Even if an internal methionine is used to produce an undetectable, N terminally deleted ORC5, the protein would lack 80% of the AAA+ ATPase domain, including the Walker A motif. The ORC5-depleted cells show normal chromatin binding of MCM2–7 and initiate replication from a similar number of origins as WT cells. In addition, we introduced a second mutation in ORC2 in the ORC5 mutant cells, rendering both ORC5 and ORC2 proteins undetectable in the same cells and destabilizing the ORC1, ORC3, and ORC4 proteins. Yet the double mutant cells grow, recruit MCM2–7 normally to chromatin, and initiate DNA replication with normal number of origins. Thus, in these selected cancer cells, either a crippled ORC lacking ORC2 and ORC5 and present at minimal levels on the chromatin can recruit and load enough MCM2–7 to initiate DNA replication, or human cell lines can sometimes recruit MCM2–7 to origins independent of ORC.
