Article Synopsis
  • Some men with prostate cancer take a treatment called androgen deprivation therapy (ADT), but it can be used too much, which can cause health problems like diabetes and weak bones.
  • We did a study to understand why some doctors overuse ADT and how to stop it, using different theories and surveys to gather information from urologists.
  • From our survey, we found that some doctors are less likely to stop giving ADT unnecessarily, and that better communication and teamwork might help reduce its overuse.

Plant tetrapyrrole biosynthesis (TPB) takes place in plastids and provides the chlorophyll and heme required for photosynthesis and many redox processes throughout plant development. TPB is strictly regulated, since accumulation of several intermediates causes photodynamic damage and cell death. Protoporphyrinogen oxidase (PPO) catalyzes the last common step before TPB diverges into chlorophyll and heme branches.

Redox-dependent thiol-disulfide switches of cysteine residues are one of the significant posttranslational modifications of proteins to control rapidly their stability, activity, and protein interaction. Redox control also modulates the tetrapyrrole biosynthesis (TBS). Among the redox-dependent TBS enzymes, 5-aminolevulinic acid dehydratase (ALAD) was previously recognized to interact with reductants, such a thioredoxins or NADPH-dependent thioredoxin reductase C.

Purpose: Modifications to surgical technique, particularly the widespread adoption of robotic surgery, have been proposed to improve functional recovery after prostate cancer surgery. However, rigorous comparison of men in historical vs contemporary practice to evaluate the cumulative effect of these changes on urinary and sexual function after radical prostatectomy is lacking.

Materials And Methods: We compared prospectively collected patient-reported urinary and sexual function from historical (PROSTQA [Prostate Cancer Outcomes and Satisfaction With Treatment Quality Assessment study], n=235) and contemporary (MUSIC-PRO [Michigan Urological Surgery Improvement Collaborative Patient Reported Outcome] registry, n=1,215) cohorts at the University of Michigan to understand whether modern techniques have resulted in functional improvements for men undergoing prostate cancer surgery.

Redox regulation of plastid gene expression and different metabolic pathways promotes many activities of redox-sensitive proteins. We address the question of how the plastid redox state and the contributing reducing enzymes control the enzymes of tetrapyrrole biosynthesis (TBS). In higher plants, this metabolic pathway serves to produce chlorophyll and heme, among other essential end products.

Background: Sexual dysfunction represents a critical aspect of quality of life for adolescent and young adult cancer survivors. Studies have consistently documented that adolescents and young adults report greater psychological and physical morbidity than older survivors and healthy peers, including elevated rates of sexual dysfunction, often accompanied by lower satisfaction with sex life and delays in meeting sexual milestones. Moreover, sexual dysfunction, body image concerns, and fertility status affect their confidence in being both physically and emotionally intimate.
