Article Synopsis
  • Enhancers play a key role in controlling gene expression specific to certain tissues, and variations within these regions may impact cancer progression and treatment resistance, though the exact ways they do this are not fully understood.
  • Researchers studied an enhancer linked to the DPD gene, which is important for how the body processes the cancer drug 5-FU.
  • They found that a common genetic variant affects how well 5-FU works by influencing the recruitment of a transcription factor and altering the interaction between the enhancer and promoter, providing new insights into drug resistance mechanisms.

Enhancers are critical for regulating tissue-specific gene expression, and genetic variants within enhancer regions have been suggested to contribute to various cancer-related processes, including therapeutic resistance. However, the precise mechanisms remain elusive. Using a well-defined drug-gene pair, we identified an enhancer region for dihydropyrimidine dehydrogenase (DPD, gene) expression that is relevant to the metabolism of the anti-cancer drug 5-fluorouracil (5-FU).

Testosterone and its metabolites facilitate male-typical social behaviors in sexually experienced animals. The metabolite estradiol acts on estrogen receptors (ERs) within the bed nucleus of the stria terminalis (BNST) to facilitate socio-sexual behaviors. While circulating testosterone does not increase in naïve males, aromatase-expressing neurons within the BNST of naïve males are necessary for sex recognition, suggesting that local estradiol production may be responsible.

Compatible osmolytes are a broad class of small organic molecules employed by living systems to combat environmental stress by enhancing the native protein structure. The molecular features that make for a superior biopreservation remain elusive. Through the use of time-resolved and steady-state spectroscopic techniques, in combination with molecular simulation, insight into what makes one molecule a more effective compatible osmolyte can be gained.
