Autophagy and apoptosis are two important cellular processes with complex and intersecting protein networks; as such, they have been the subjects of intense investigation. Recent advances have elucidated the key players and their molecular circuitry. For instance, the discovery of Beclin-1’s interacting partners has resulted in the identification of Bcl-2(More)
Oral squamous cell carcinoma (OSCC) acquires the top most position among the other malignancies and patients die with this disease complication within 5years. One of the causes behind this scenario is the identified sub-population in heterogeneous tumor mass that are purported as cancer stem cells (CSCs) or tumor-initiating cells (TICs). Oral CSCs(More)
The functional relevance of autophagy in tumor formation and progression remains controversial. Autophagy can promote tumor suppression during cancer initiation and protect tumors during progression. Autophagy-associated cell death may act as a tumor suppressor, with several autophagy-related genes deleted in cancers. Loss of autophagy induces genomic(More)
Oncophagy (cancer-related autophagy) has a complex dual character at different stages of tumor progression. It remains an important clinical problem to unravel the reasons that propel the shift in the role of oncophagy from tumor inhibition to a protective mechanism that shields full-blown malignancy. Most treatment strategies emphasize curbing protective(More)
Regardless of rapid progression in the field of autophagy, it remains a challenging task to understand the cross talk with apoptosis. In this study, we overexpressed Ulk1 in HeLa cells and evaluated the apoptosis-inducing potential of the Ulk1 gene in the presence of cisplatin. The gain of function of Ulk1 gene showed a decline in cell viability and colony(More)
Autophagy in cancer is an intensely debated concept in the field of translational research. The dual nature of autophagy implies that it can potentially modulate the pro-survival and pro-death mechanisms in tumor initiation and progression. There is a prospective molecular relationship between defective autophagy and tumorigenesis that involves the(More)
AIMS The present study evaluated the potential role of soybean lectin's (SBL) anticancer effect in vitro in different cancer cell lines and the therapeutic effectiveness in vivo in Dalton's lymphoma (DL) bearing mice model. MAIN METHODS The effect of SBL on cell growth and viability was measured using MTT assay in different cancer cells in vitro.(More)
AIM Abrus agglutinin (AGG) from the seeds of Indian medicinal plant Abrus precatorius belongs to the class II ribosome inactivating protein family. In this study we investigated the anticancer effects of AGG against human hepatocellular carcinoma in vitro and in vivo. METHODS Cell proliferation, DNA fragmentation, Annexin V binding,(More)
In this study we unravel the mechanism underlying the antitumorigenic effects of Peanut agglutinin (PNA) isolated from Arachis hypogea in Dalton's lymphoma (DL) bearing mice and elucidated the mechanism in vitro in HeLa cells. In vivo PNA administration at 1 and 2 mg/kg body weight reduced DL proliferation with increase in autophagic and apoptotic(More)
Conventional therapeutics are often frequented with recurrences, refraction and regimen resistance in oral cavity cancers which are predominantly manifested by cancer stem cells (CSCs). During oncoevolution, cancer cells may undergo structural and functional reprogramming wherein they evolve as highly tolerant CSC phenotypes with greater survival(More)
