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.

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.

China has been Africa’s largest trading partner since 2009, and as commerce and investment have increased, so have flows of people in both directions. With an estimated 1 million to 2 million Chinese migrants across Africa, some countries have relaxed their short-term visa requirements in hopes of facilitating cultural and business exchanges. High levels of Chinese investment do not, however, correlate with more liberal visa policies, as this article explores.

With more than 3 million Venezuelans having fled their country in crisis, this event features the release of an MPI-OAS report that examines the creative responses that host countries in Latin America are providing. These include the opening of legal pathways to residence, access to formal labor markets, and greater use of forms of ID for recognition.

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.

The Cleveland Cavaliers are planning to reopen their training facility for limited individual workouts amid the coronavirus pandemic.

OBJECTIVE

Diabetes is a rapidly growing health problem in low- and middle-income countries (LMICs), but empirical data on its prevalence and relationship to socioeconomic status are scarce. We estimated diabetes prevalence and the subset with undiagnosed diabetes in 29 LMICs and evaluated the relationship of education, household wealth, and BMI with diabetes risk.

As highly industrialized countries ramp up their border controls, human smugglers are playing a central role in moving migrants through key migration corridors around the world. Despite the illicit nature of their work and being cast as villains in the public eye, smugglers have complex, multifaceted relationships with their clients. At times, the relationship can be mutually beneficial or even lifesaving; at others, it can be predatory and dangerous, as this article explores.

The Association is asking member dentists and their dental teams to increase their vigilance over phishing emails as a result of the coronavirus, known as COVID-19.

It’s not easy raising a child, and when he or she is affected by a severe disorder or disease, you have a greater challenge ahead of you. You have to put in extra effort, energy and thought into your child’s development and progress, one aspect of which includes their education. Some parents of children with special needs may be tempted to overprotect by keeping them in cloistered environments and limiting their interaction with the outside world. This usually only hampers the child instead of helping them. If you’re a parent with a child who has special needs, here’s some strategies:

* Understand your child: Some children may be able to express themselves while others are limited because of their disability. Whatever the case, understand your child and know that they have a mind of their own even if they are unable to speak it. Instead of forcing your will on them, get to know what they wish to do and cater to their needs as much as possible as long as it does not cause them any harm.

* Be patient: It’s a tough task, but you need to have an enormous amount of patience with your child. You need to condition yourself to be patient through practice and experience, otherwise you and your child will be subject to a great deal of stress.

* Decide on their education: There are many options for providing education to your special needs child, so look for what is available in your area. If you plan to homeschool, you will need to do some research before you’re up to the task. Many feel that it’s better to let the professionals handle this task who are trained and more experienced. Also, your child gets to mingle with other children and interact with them on a regular basis, which is very important to his or her social development.

*Think about inclusive classrooms: Parents often want their special needs children to attend regular schools. Learn about inclusive classrooms and determine if it is a good fit for your child. Consider if your child is up to the task of being educated with general education children and if he/she can cope with the curriculum in such classrooms. Although teachers in inclusive classrooms are trained to deal with children with special needs, there may be times when your child could be bullied or teased by the other kids for not being like them. Take all these facts into consideration before you decide on an inclusive classroom for your child.


Children with special needs need all the help and support they can get from parents and teachers, and it’s up to you to decide on the best form of education for them.

WASHINGTON – Even as governments in Latin America and the Caribbean have taken generous and innovative steps to address forced displacement from Venezuela and more recently Nicaragua, the warm welcome has cooled in places amid the vast scale of the inflows, strains on public services and growing public concern.

Felipe Muñoz, Advisor to the President of Colombia for the Colombian-Venezuelan Border, discusses how Colombia is coping with the influx of Venezuelan migrants, plans for future policy decisions surrounding this migration, and developments in regional and international cooperation.

Leading policymakers and key stakeholders from Latin America, as well as representatives of major international institutions, offer their views on the challenges ahead as Latin American governments seek to chart strategies for responding to large-scale forced migration flows, such as those from Venezuela and Nicaragua.

Though Colombians displaced by a decades-long civil war found a welcome refuge in Ecuador, life has become more difficult for them in recent years, in part as a result of the influx of Venezuelans seeking safety. This article draws on surveys of migrants in Quito, comparing and contrasting the experiences of Colombians and Venezuelans, and assessing their perceptions of discrimination, victimization, trust in institutions, and hopes for the future.

This webinar marks the release of MPI's Latin American and Caribbean Migration Portal that offers up-to-date, authoritative research and data on migration trends and policies, and a report examining the policy responses of 11 countries in Latin America and the Caribbean to increased Venezuelan and Nicaraguan migration.

Large-scale displacement from Venezuela and Nicaragua is reshaping the migration landscape in much of Latin America and the Caribbean. This report, accompanied by the launch of a new Migration Portal offering research and analysis on the region, examines the immigration and integration policy responses of 11 countries, including pathways to legal status and measures to integrate newcomers into schools, health-care systems, and labor markets.

Until recently, the Venezuelan immigrant population in the United States was relatively small compared others from South America. But it has grown significantly, reaching 394,000 in 2018, as Venezuela's destabilization has driven large-scale emigration. Compared to other immigrants in the United States, Venezuelans have higher levels of education but are also more likely to live in poverty, as this Spotlight explores.

Felipe Muñoz, Advisor to the President of Colombia for the Colombian-Venezuelan Border, discusses how Colombia is coping with the influx of Venezuelan migrants, plans for future policy decisions surrounding this migration, and developments in regional and international cooperation.
