Background:

• Dihydroceramide (dhCer) was historically viewed as an inactive metabolic precursor to ceramide.
• Emerging evidence demonstrates dhCer's significant involvement in diverse cellular processes.

Purpose of the Study:

• To review the current understanding of dihydroceramide's biological functions.
• To summarize enzymes involved in dihydroceramide biosynthesis.
• To explore the role of dhCer in cancer and related cellular mechanisms.

Main Methods:

• Literature review of recent studies on dihydroceramide.
• Analysis of research on dhCer biosynthesis pathways.
• Synthesis of findings related to dhCer's impact on cancer progression.

Main Results:

• Dihydroceramide actively regulates critical cellular processes including apoptosis, autophagy, and cell cycle arrest.
• dhCer is implicated in ER stress and oxidative stress responses.
• Specific bioactive compounds can modulate dhCer levels in cancer cells.

Conclusions:

• Dihydroceramide is a bioactive sphingolipid with significant roles beyond ceramide synthesis.
• dhCer's involvement in cancer highlights its potential as a therapeutic target.
• Modulating dhCer levels offers promising strategies for cancer treatment.
