Does it matter if those who matter don't mind? Effects of gang versus delinquent peer group membership on labeling processes.

2020

Criminology : an interdisciplinary journal

Buchanan M, Krohn MD

Plain English
This study looked at how being in a gang or hanging out with delinquent peers affects young people's self-esteem and their behavior after being arrested. Researchers analyzed data from 961 youths and found that both gang members and those with delinquent friends were not negatively affected in terms of self-esteem after an arrest, while those with fewer delinquent friends experienced a drop in self-esteem that led to more delinquency later on. This matters because it shows that the type of social group youth belong to can influence how they react to arrests, suggesting that interventions should consider social environments. Who this helps: This helps youth, parents, and professionals working with at-risk young people.

Frontiers in oncology

Aguilar-Mahecha A, Joseph S, Cavallone L, Buchanan M, Krzemien U +2 more

Plain English
This study looked at how to improve treatment for a patient with HER-2 positive gastric cancer using personalized medicine approaches. Researchers created a model of the patient's cancer and tested a specific drug, T-DM1, which the patient initially responded to but eventually relapsed after six months. By tracking certain genetic markers in the patient's blood, they found a stronger connection between these markers and the patient's response to treatment compared to traditional methods. Who this helps: This benefits gastric cancer patients and their doctors by offering tailored treatment options based on individual responses.

Metastatic Breast Carcinoma-Associated Fibroblasts Have Enhanced Protumorigenic Properties Related to Increased IGF2 Expression.

2019

Clinical cancer research : an official journal of the American Association for Cancer Research

Gui Y, Aguilar-Mahecha A, Krzemien U, Hosein A, Buchanan M +4 more

Plain English
This study looked at a type of cell called carcinoma-associated fibroblasts (CAFs) in metastatic breast cancer to understand their role in helping tumors grow. The researchers found that CAFs taken from metastatic sites had much stronger effects on cancer cell growth and survival compared to those from primary tumors or normal breast tissue. Specifically, these metastatic CAFs had increased levels of a protein called IGF2, which contributes to tumor growth and can also weaken the immune response. Who this helps: This information can benefit doctors and researchers working to develop better treatments for metastatic breast cancer patients.

Molecular cancer research : MCR

Sirois I, Aguilar-Mahecha A, Lafleur J, Fowler E, Vu V +32 more

Plain English
This study looked at why some patients with triple-negative breast cancer (TNBC) do not respond to chemotherapy. Researchers found that certain resistant cancer cells have a unique structure and rely heavily on fatty acids for energy, revealing a potential weakness related to a protein called PLIN4, which helps store fat in these cells. By targeting PLIN4, new treatments could be developed for patients who currently struggle with this tough-to-treat cancer. Who this helps: This helps patients with chemoresistant triple-negative breast cancer.
