The actin cytoskeleton is extremely dynamic and supports diverse cellular functions in many physiological and pathological processes, including tumorigenesis. However, the mechanisms that regulate the actin-related protein 2/3 (ARP2/3) complex and thereby promote actin polymerization and organization in cancer cells are not well-understood. We previously implicated the proline-rich 11 (PRR11) protein in lung cancer development. In this study, using immunofluorescence staining, actin polymerization assays, and siRNA-mediated gene silencing, we uncovered that cytoplasmic PRR11 is involved in F-actin polymerization and organization. We found that dysregulation of PRR11 expression results in F-actin rearrangement and nuclear instability in non-small cell lung cancer cells. Results from molecular mechanistic experiments indicated that PRR11 associates with and recruits the ARP2/3 complex, facilitates F-actin polymerization, and thereby disrupts the F-actin cytoskeleton, leading to abnormal nuclear lamina assembly and chromatin reorganization. Inhibition of the ARP2/3 complex activity abolished irregular F-actin polymerization, lamina assembly, and chromatin reorganization due to PRR11 overexpression. Notably, experiments with truncated PRR11 variants revealed that PRR11 regulates F-actin through different regions. We found that deletion of either the N or C terminus of PRR11 abrogates its effects on F-actin polymerization and nuclear instability and that deletion of amino acid residues 100–184 or 100–200 strongly induces an F-actin structure called the actin comet tail, not observed with WT PRR11. Our findings indicate that cytoplasmic PRR11 plays an essential role in regulating F-actin assembly and nuclear stability by recruiting the ARP2/3 complex in human non-small cell lung carcinoma cells.

Incorporation of ribonucleotides into DNA can severely diminish genome integrity. However, how ribonucleotides instigate DNA damage is poorly understood. In DNA, they can promote replication stress and genomic instability and have been implicated in several diseases. We report here the impact of the ribonucleotide rATP and of its naturally occurring damaged analog 1,N6-ethenoadenosine (1,N6-ϵrA) on translesion synthesis (TLS), mediated by human DNA polymerase η (hpol η), and on RNase H2–mediated incision. Mass spectral analysis revealed that 1,N6-ϵrA in DNA generates extensive frameshifts during TLS, which can lead to genomic instability. Moreover, steady-state kinetic analysis of the TLS process indicated that deoxypurines (i.e. dATP and dGTP) are inserted predominantly opposite 1,N6-ϵrA. We also show that hpol η acts as a reverse transcriptase in the presence of damaged ribonucleotide 1,N6-ϵrA but has poor RNA primer extension activities. Steady-state kinetic analysis of reverse transcription and RNA primer extension showed that hpol η favors the addition of dATP and dGTP opposite 1,N6-ϵrA. We also found that RNase H2 recognizes 1,N6-ϵrA but has limited incision activity across from this lesion, which can lead to the persistence of this detrimental DNA adduct. We conclude that the damaged and unrepaired ribonucleotide 1,N6-ϵrA in DNA exhibits mutagenic potential and can also alter the reading frame in an mRNA transcript because 1,N6-ϵrA is incompletely incised by RNase H2.

With issues of immigration policy very much at the forefront of the 2016 elections, this annual conference offers policy and legal analysis on key immigration topics facing the country and the incoming administration and Congress in 2017.

The 13th annual Immigration Law & Policy Conference offered policy and legal analysis on key immigration topics, including: the election and the future of immigration policy; refugee resettlement in the United States; immigration detention and enforcement; and the impacts of the Supreme Court opinion in the important U.S. vs Texas case

As policymakers in a number of countries, the United States among them, debate limiting family-based immigration, this issue brief explores family-migration trends and policies in the United States, Australia, Canada, the United Kingdom, and several other European countries. Family admissions play a key role, even in countries that prioritize economic or other immigration streams.

The White House immigration plan offered as a solution to resolve the fate of DREAMers seeks legal immigration cuts unlike any seen since 1924. In addition to a decrease of up to 40 percent in family-sponsored immigration, the proposal demands vast increases in enforcement and a retrenchment in protections for those seeking humanitarian relief. In exchange, one-sixth of the unauthorized population could gain legal status.

President Trump has made reshaping the U.S. immigration system a top priority. Yet the fragmented nature of policy-making in the United States—with power split between branches and levels of government—has made it difficult to pursue some of his most ambitious proposals. This report explores the evolution of migration policy under Trump, and what these changes may mean in the long run.

During its first year, the Trump administration methodically put in place a series of bureaucratic barriers that could significantly reduce opportunities for foreigners to come to the United States legally. Among the actions taken during 2017: Imposition of a much-challenged travel ban suspending the entry of nationals from certain Muslim-majority countries, cuts to refugee admissions, and increased scrutiny for visa applicants.

Faced with a lack of employment opportunities and recurrent poverty, Albanian youth migrate to Italy alone in the hopes of improving their educational prospects or making money for their families. Yet upon arrival, they face many vulnerabilities. While some protections for unaccompanied minors exist in the Italy, the system is greatly fragmented and challenges, including how to return them to Albania, remain persistent.

The Trump administration’s decision to terminate the Deferred Action for Childhood Arrivals (DACA) deportation-relief program launched in 2012 has sparked new urgency to find a longer-term fix for "DREAMers," the unauthorized immigrants brought to the United States as children. This Policy Beat article examines movement in the courts and in Congress on the DREAM Act and similar proposals, exploring likely paths forward.

In its first year, the Trump administration moved to deliver on some of Donald Trump’s campaign promises on immigration, including ramping up enforcement in the U.S. interior and ending the Deferred Action for Childhood Arrivals (DACA) program. The administration also announced the termination of Temporary Protected Status (TPS) for nationals of some countries. This article explores some of the top policy changes.

On the campaign trail, Donald Trump made immigration the centerpiece of his campaign, offering a more detailed policy agenda than on any other issue. In the year since the election that propelled the Republican into the White House, how has the Trump administration’s record matched up with the rhetoric? This policy brief examines the executive orders and other changes to existing policy and practice made during 2017.

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.

The Trump administration has significantly cranked up the immigration enforcement machinery in the U.S. interior. Yet even as arrests and deportations are up in the early Trump months, they remain less than half their peaks. This report demonstrates how pushback from California and other "sanctuary" locations makes it quite unlikely that ICE will be able to match record enforcement levels.

Discussion at this event focused on findings from MPI's report examining the interior immigration enforcement system in the United States, including ICE data on deportations and arrests, and the responses of state and local governments, civil society, and consulates.

The Trump administration took sweeping action in 2018 to slow legal immigration, make life harder for some immigrants already in the United States, rebuff would-be asylum seekers, and reduce refugee resettlement. Shaping a narrative of crisis at the border, the administration significantly changed the U.S. asylum system, deployed troops and tear gas, and separated families—yet Central American migrants continued to arrive.

Approximately 11,500 unaccompanied children were apprehended at the U.S.-Mexico border in May, putting this year on track to exceed 2014's surge. As the U.S. government struggles to care for these child migrants, with public outrage mounting over reports of unsafe, filthy conditions in initial Border Patrol custody, the failure of the executive branch and Congress to plan for increased shelter and care demands are increasingly apparent, as this article explores.

As federal and state governments ramp up efforts to implement the Workforce Innovation and Opportunity Act, these fact sheets compare key characteristics of the foreign born and the U.S. born that are relevant to understanding needs for adult education and workforce training services. The fact sheets cover the United States, the 20 states and 25 counties with the largest immigrant populations, and New York City.

This fact sheet uses U.S. and Mexican apprehensions data to trace the evolving trends in unaccompanied child and family migration from Central America through Mexico and to the United States, and discusses the push factors and pull factors responsible for the increase in flows seen in recent years, as well as the growing role of smuggling organizations.

During his first 100 days in office, President Trump has taken a sweeping set of actions on immigration, ranging from imposing a travel ban to cutting refugee admissions, "extreme" vetting, and fortifying immigration enforcement at the border and in the U.S. interior. This fact sheet examines the major immigration actions taken to date, legal challenges, and related policy and personnel developments.

As the 100-day milestone for the Trump administration approaches, MPI's Doris Meissner and Muzaffar Chishti are joined by the former Director of U.S. Immigration and Customs Enforcement, Julie Myers Wood, and former DHS Assistant Secretary for Policy and Planning C. Stewart Verdery for a discussion of the administration's track record to date on immigration, the policies articulated in its executive orders, legal challenges, reactions by publics and policymakers, and the possible long-term effects of these policies.

Marking the release of an MPI study, this discussion examines the operation of today’s interior enforcement system and how state and local governments, civil society, and consulates are responding.

This discussion on the 1986 Immigration Reform and Control Act (IRCA) showcases MPI Fellow Charles Kamasaki's book, Immigration Reform: The Corpse That Will Not Die. Kamasaki is joined by other veterans of the IRCA debate for a conversation on the lessons, the intended and unintended consequences, and how the law’s legacy has shaped contemporary politics on immigration.

While the Global Compact for Safe, Orderly, and Regular Migration was formally adopted by 164 of the UN's 193 Member States, it's worth asking how it became a point of contention and ultimately was rejected by more than a dozen countries. The answer? A long lag time between negotiation and adoption, during which overheated claims against it went largely unanswered, as this commentary explores.

Migration and development are intimately linked, but they have not always shared the international policy stage. As UN Member States kick off negotiations for the Global Compact for Safe, Orderly, and Regular Migration—and with adoption planned for 2018—this brief examines the evolving relationship between these policy areas and considers what a global compact has to offer, if well designed.

Development assistance may be a blunt tool for reshaping migration patterns—and indeed one that could increase flows over the short term. Shifting the focus away from increasing individuals’ skills and assets toward investments in the broader economic or governance structures that are a prerequisite for growth and stability may offer more alternatives to emigration in the long run.

As the final phase of preparations for the historic adoption of a Global Compact for Safe, Orderly, and Regular Migration approaches, this webinar explores two central objectives of the compact: enhancing the availability and flexibility of pathways for regular migration, and investing in skills development.

The Member States of the United Nations convened in December to adopt the Global Compact for Safe, Orderly, and Regular Migration (GCM). Ahead of the adoption, this side event in Marrakech (open only to those with GFMD credentials) considered the coordination and mechanisms most needed to achieve the commitments laid out in the GCM.

The world’s first international agreement on migration was approved by 164 countries in December 2018, but not without turbulence. U.S. withdrawal from the nonbinding Global Compact on Safe, Orderly, and Regular Migration, on grounds it could impinge on sovereignty, triggered similar actions by others, particularly in Eastern Europe. Amid ongoing political ripple effects, attention now turns to implementation of the deal's goals.

Faced with labor shortages in key sectors of the economy, South Korea has moved carefully in recent decades toward accepting greater numbers of workers—albeit in temporary fashion. Its Employment Permit System, launched in 2003, earned international accolades for bringing order and legality to immigration in the country, although several challenges remain to be addressed as this Country Profile explores.

This volume from MPI's Transatlantic Council on Migration aims to fill the analytical gap regarding the question of what greater global cooperation on governing the flow of international migrants could achieve. The book focuses on a set of fundamental questions: What are the key steps to building a better, more cooperative system of governance? What are the goals that can be achieved through greater international cooperation? And, most fundamentally, who (or what) is to be governed?

This report by MPI and the Asian Development Bank lays out a realistic roadmap toward freer movement among skilled professionals within the ASEAN Economic Community (AEC), encouraging cooperation among ASEAN Member States in recognizing foreign qualifications and making government investments in training and educations systems that prepare workers in accordance with common standards.

While it has been years since the Association of Southeast Asian Nations signed accords to facilitate the movement of professionals in seven occupations, implementation of these Mutual Recognition Arrangements remains "painfully slow and uneven across countries." This final report in an MPI-Asian Development Bank series explores MRA implementation by sector, and offers recommendations to help achieve the goal of greater skill mobility in Southeast Asia.
