What is Bromelain Anti-Cancer Pharmacological Effects?

Bromelain anti-cancer pharmacological effects refer to the proteolytic enzyme's mechanisms of inducing apoptosis, inhibiting metastasis, and modulating immunity in various cancer cell lines and models.

Studies demonstrate bromelain's cytotoxicity in gastrointestinal, colorectal, and cholangiocarcinoma cells through ROS production, autophagy, and synergy with N-acetylcysteine. Key papers include Pavan et al. (2012, 466 citations) reviewing therapeutic applications and Chang et al. (2019, 71 citations) showing proliferation inhibition in colorectal cancer. Over 10 provided papers span reviews and in vitro experiments from 2012-2022.

Key Challenges

Why It Matters

Bromelain offers adjunctive cancer therapy potential by enhancing chemotherapy efficacy and reducing tumor proliferation, as shown in Amini et al. (2014, 68 citations) where bromelain with N-acetylcysteine inhibited gastrointestinal cancer cell survival. Chang et al. (2019) reported ROS-mediated autophagy in colorectal cancer cells, suggesting natural protease alternatives to synthetic drugs. Müller et al. (2016, 58 citations) confirmed superior anti-tumor effects over papain in cholangiocarcinoma, impacting development of low-toxicity treatments from pineapple extracts.

Key Research Challenges

Translating In Vitro to In Vivo

Most evidence comes from cell lines like HT29 and MKN45, lacking robust xenograft or clinical data. Pavan et al. (2012) note limited human trials despite preclinical promise. Amini et al. (2014) highlight need for bioavailability studies.

Standardizing Bromelain Extracts

Variations in fruit vs. stem bromelain compositions affect potency, as detailed in Rathnavelu et al. (2016). Manzoor et al. (2016, 92 citations) describe extraction challenges impacting reproducibility. Chakraborty et al. (2021) emphasize purification inconsistencies.

Elucidating Molecular Mechanisms

Precise pathways for apoptosis and immunomodulation remain unclear beyond ROS and autophagy. Chang et al. (2019) link ROS to colorectal effects but not all cancers. Morris et al. (2013, 52 citations) implicate varied mechanisms in gastric cells.
