Harnessing Postbiotics to Boost Chemotherapy: N-Acetylcysteine and Tetrahydro β-Carboline Carboxylic Acid as Potentiators in Pancreatic and Colorectal Cancer.

ABSTRACT:

Background

Pancreatic cancer (PC) and colorectal cancer (CRC) are among the most lethal malignancies, with growing evidence pointing to the gut microbiota's role in their progression. This study aimed to explore the anticancer potential of two microbiota-derived postbiotics, N-acetylcysteine (NAC) and tetrahydro β-carboline carboxylic acid (THC), in targeting some hallmark traits of PC and CRC, both as standalone agents and in combination with standard chemotherapeutics (gemcitabine for PC and 5-fluorouracil (5-FU) for CRC).

Methods

Cell viability assays and IC₅₀ determination was assessed using either the Muse™ Count & Viability Kit or the Sulforhodamine B assay; cell death was determined by Annexin V/Propidium Iodide and cell cycle assessed by Propidium Iodide w
