The leinamycin family of polyketides are promising antitumor antibiotics, yet several aspects of their biosynthesis remain elusive. All leinamycin family members bear a sulfur-containing moiety which is essential for the anticancer activity exhibited by leinamycin. The key building blocks required for the incorporation of these functionalities are introduced in the final module of the polyketide synthase (PKS), which elegantly combines β-branching and thiocysteine incorporation to generate a diverse library of sulfur-based molecular scaffolds.

CR, complete response; DLBCL, diffuse large B-cell lymphoma; PD, progressive disease; PR, partial response; R/R, relapsed/refractory; SD, stable disease.

We hypothesized that the presence of specific gene mutations may predict outcomes. We performed targeted sequencing of a 69-gene panel in 117 limited-stage FL patients treated with radiotherapy and identified recurrently mutated genes.
