Beliefs and Attitudes about Vermont's Buprenorphine Decriminalization Law among Clinicians Who Prescribe Buprenorphine.

Background: On June 1, 2021, Vermont repealed all criminal penalties for possessing 224 milligrams or less of buprenorphine. We examined the potential impact of decriminalization with a survey of Vermont clinicians who prescribed buprenorphine within the past year.

Methods: All 638 Vermont clinicians with a waiver to prescribe buprenorphine were emailed the survey by Vermont Department of Health; 117 responded.

Attitudes and beliefs about Vermont's 2021 buprenorphine decriminalization law among residents who use illicit opioids.

Background: In July 2021, Vermont removed all criminal penalties for possessing 224mg or less of buprenorphine.

Methods: Vermont residents (N=474) who used illicit opioid drugs or received treatment for opioid use disorder in the past 90 days were recruited for a mixed-methods survey on the health and criminal legal effects of decriminalization. Topics assessed included: motivations for using non-prescribed buprenorphine, awareness of and support for decriminalization, and criminal legal system experiences involving buprenorphine.

Hepatitis B and Hepatitis D Viruses: A Comprehensive Update with an Immunological Focus.

Hepatitis B virus (HBV) and hepatitis delta virus (HDV) are highly prevalent viruses estimated to infect approximately 300 million people and 12-72 million people worldwide, respectively. HDV requires the HBV envelope to establish a successful infection. Concurrent infection with HBV and HDV can result in more severe disease outcomes than infection with HBV alone.

Epigenetic inhibition of adaptive bypass responses to lapatinib by targeting BET Bromodomains.

The characterization of kinases as oncogenic drivers has led to more than 30 FDA-approved targeted kinase inhibitors for cancer treatment. Unfortunately, these therapeutics fail to have clinical durability because of adaptive responses from the kinome and transcriptome that bypass inhibition of the targeted pathway. In our recent work, we describe a method to prevent these adaptive responses at an epigenetic level, generating a durable response to kinase inhibition.

Targeting the Breast Cancer Kinome.

Protein kinases are highly tractable targets for the treatment of many cancers including breast cancer, due to their essential role in tumor cell proliferation and survival. Sequencing of the breast cancer genome and transcriptome has defined breast cancer as a heterogeneous disease that is classified into five molecular subtypes: luminal A, luminal B, HER2-enriched, basal-like, and claudin-low. Each subtype displays a unique expression profile of protein kinases that can be targeted by small molecule kinase inhibitors or biologics.

Weight loss reduces basal-like breast cancer through kinome reprogramming.

Background: Obesity is associated with an aggressive subtype of breast cancer called basal-like breast cancer (BBC). BBC has no targeted therapies, making the need for mechanistic insight urgent. Reducing adiposity in adulthood can lower incidence of BBC in humans.

Inhibition of Lapatinib-Induced Kinome Reprogramming in ERBB2-Positive Breast Cancer by Targeting BET Family Bromodomains.

Therapeutics that target ERBB2, such as lapatinib, often provide initial clinical benefit, but resistance frequently develops. Adaptive responses leading to lapatinib resistance involve reprogramming of the kinome through reactivation of ERBB2/ERBB3 signaling and transcriptional upregulation and activation of multiple tyrosine kinases. The heterogeneity of induced kinases prevents their targeting by a single kinase inhibitor, underscoring the challenge of predicting effective kinase inhibitor combination therapies.

Role of HGF in epithelial-stromal cell interactions during progression from benign breast disease to ductal carcinoma in situ.

Introduction: Basal-like and luminal breast cancers have distinct stromal-epithelial interactions, which play a role in progression to invasive cancer. However, little is known about how stromal-epithelial interactions evolve in benign and pre-invasive lesions.

Methods: To study epithelial-stromal interactions in basal-like breast cancer progression, we cocultured reduction mammoplasty fibroblasts with the isogenic MCF10 series of cell lines (representing benign/normal, atypical hyperplasia, and ductal carcinoma in situ).
