Obesity is a risk factor for developing breast cancer, and significantly increases mortality rates in patients diagnosed with this disease. Drivers of this unfortunate relationships are multifactorial, with obesity-induced changes in the epigenetic state of breast cancer cells being identified as a critical mechanism that impact survival, metastasis, and therapeutic responses. Recent studies have investigated the epigenetic landscape of breast cancer to elucidate the molecular interplay between the breast tissue epigenome and its cellular microenvironment.

Immunotherapies have revolutionized the treatment of B-cell acute lymphoblastic leukemia (B-ALL), but the duration of responses is still sub-optimal. We sought to identify mechanisms of immune suppression in B-ALL and strategies to overcome them. Plasma collected from children with B-ALL with measurable residual disease after induction chemotherapy showed differential cytokine expression, particularly IL-7, while single-cell RNA-sequencing revealed the expression of genes associated with immune exhaustion in immune cell subsets.
