Protests and use of rubber bullets in South Africa: Unspoken pain and trauma of eye injuries.

INTRODUCTION: The article examines the experiences of protesters and bystanders who have sustained eye injuries from rubber bullets fired by the police. Use of rubber bullets by police officers during public protests is officially regulated, but there is insufficient documentation about the nature of fatal and non-fatal injuries linked to rubber bullet use during protests in South Africa. METHODS: We pres-ent three case studies based on data gathered from student protests, community protests, and media reports. Through the analysis of these sources, the article presents the personal stories of individuals who have experienced eye injuries, detailing how the incidents occurred and the subsequent impact on their lives. It also examines the accessibility of medical, psychological, and legal services available to victims in addressing the consequences of these injuries. RESULTS: The cases studies illustrate that rubber bullets were used frequently and often without due caution by police officers during the events examined. The use of rubber bullets was linked to numerous eye injuries, resulting in lasting psycho-logical and physical consequences for those affected. DISCUSSION: Rubber bullet-related eye injuries during protests are disturbingly common in South Africa. Consequently, there is an urgent need to provide essential services and support to those who suffer from these life-altering incidents.

Enhancer RNA Expression in Response to Glucocorticoid Treatment in Murine Macrophages.

Glucocorticoids are potent anti-inflammatory drugs; however, their molecular mode of action remains complex and elusive. They bind to the glucocorticoid receptor (GR), a nuclear receptor that controls gene expression in almost all tissues in a cell type-specific manner. While GR's transcriptional targets mediate beneficial reactions in immune cells, they also harbor the potential of adverse metabolic effects in other cell types such as hepatocytes. Here, we have profiled nascent transcription upon glucocorticoid stimulation in LPS-activated primary murine macrophages using 4sU-seq. We compared our results to publicly available nascent transcriptomics data from murine liver and bioinformatically identified non-coding RNAs transcribed from intergenic GR binding sites in a tissue-specific fashion. These tissue-specific enhancer RNAs (eRNAs) correlate with target gene expression, reflecting cell type-specific glucocorticoid responses. We further associate GR-mediated eRNA expression with changes in H3K27 acetylation and BRD4 recruitment in inflammatory macrophages upon glucocorticoid treatment. In summary, we propose a common mechanism by which GR-bound enhancers regulate target gene expression by changes in histone acetylation, BRD4 recruitment and eRNA expression. We argue that local eRNAs are potential therapeutic targets downstream of GR signaling which may modulate glucocorticoid response in a cell type-specific way.
