A 56-Year-Old Male With Weight Loss, Night Sweats, Dyspnea, and Bladder Cancer.

A 56-year-old man presented with subacute night sweats, fever, and weight loss with worsening dyspnea. Computed tomography (CT) scan demonstrated miliary pattern of nodules evenly distributed throughout all lung fields. Given the patient's CT findings and temporal association with Bacille Calmette-Guerin (BCG) immunotherapy for bladder cancer, the patient was diagnosed with disseminated secondary to BCG bladder instillations.

Viral genome methylation as an epigenetic defense against geminiviruses.

Geminiviruses encapsidate single-stranded DNA genomes that replicate in plant cell nuclei through double-stranded DNA intermediates that associate with cellular histone proteins to form minichromosomes. Like most plant viruses, geminiviruses are targeted by RNA silencing and encode suppressor proteins such as AL2 and L2 to counter this defense. These related proteins can suppress silencing by multiple mechanisms, one of which involves interacting with and inhibiting adenosine kinase (ADK), a cellular enzyme associated with the methyl cycle that generates S-adenosyl-methionine, an essential methyltransferase cofactor.
