While tumors can be surgically removed and treated with chemotherapy, radiotherapy, immunotherapy, hormonal therapy, or combined therapies, current treatments often result in toxic side effects in normal tissue. Therefore, researchers are actively seeking ways to selectively eliminate cancerous cells, minimizing the toxic side effects in normal tissue. Caseins and its derivatives have shown promising anti-cancer potential, demonstrating antitumor and cytotoxic effects on cells from various tumor types without causing harm to normal cells. Collectively, these data reveals advancements in the study of caseins and their derivative peptides, particularly providing a comprehensive understanding of the molecular mechanism of action in cancer therapy. These mechanisms occur through various signaling pathways, including (i) the increase of interferon-associated STAT1 signaling,(ii) the suppression of stemness-related markers such as CD44,(iii) the attenuation of the STAT3/HIF1-α signaling,(iv) the down-expression of uPAR and PAI-1,(v) the loss of mitochondrial membrane potential and reduced intracellular ATP production,(vi) the increase of caspase-3 activity, and (vii) the suppression of TLR4/NF-кB signaling. Therefore, we conclude that casein could be an effective adjuvant for cancer treatment.  \nKeywords Milk protein · Casein · Cancer · Apoptosis · Signaling pathways  \nIntroduction  \nIn 2020, the World Health Organization (WHO) reported 18.1 million cancer cases, and 9.6 million cancer deaths in 2018, with a projected increase to 29.4 million cases in 2040.

In both sexes, lung, breast, and colorectal cancer are the leading causes of death worldwide by cancer [1] . Although tumors can be surgically removed and treated with chemotherapy, radiotherapy, immunotherapy, hormonal therapy, or combined therapies, current treatments often result in toxic side effects in normal tissue. Despite knowledge of the genetic basis and molecular mechanisms ofthis disease, cancer remains a highly aggressive pathology with a high mortality rate. This is primarily due to chemoresistance developed by tumor cells, metastasis formation, and the highly cytotoxic side effects in normal tissues [2–4] . Therefore, there is an urgent need to study new therapeutic molecules that can eradicate cancer cells while minimizing toxic side effects on healthy organs.
