CD147 and cyclophilin A: a promising potential targeted therapy for COVID-19 and associated cancer progression and chemo-resistance.

Coronavirus disease-2019 (COVID-19), as a worldwide serious issue has been shown to lead to progression and poor outcomes in cancer patients. The underlying mechanisms for SARS-CoV-2 infection's adverse effects on cancer patients have not been fully understood. We hypothesized that CD147 and Cyclophilin A (CyPA) not only can play a significant role in infection severity but also can contribute to cancer progression and chemotherapy resistance in cancer patients with COVID-19. In addition, we hypothesized that the expression of both CD147 and CyPA could be increased by Hypoxia-inducible Factor-1 alpha (HIF-1α) activation during hypoxic conditions that occurred during COVID-19. Therefore, this evidence can open a new window in the management of cancer patients during the pandemic and therapeutic approaches targeting CD147 and CyPA could be a potentially promising therapeutic approach for such patients.

Hesperetin as an anti-SARS-CoV-2 agent can inhibit COVID-19-associated cancer progression by suppressing intracellular signaling pathways.

Hesperetin, an aglycone metabolite of hesperidin with high bioavailability, recently gained attention due to its anti-COVID-19 and anti-cancer properties. Multiple studies revealed that cancer patients are prone to experience a severe form of COVID-19 and higher mortality risk. In addition, studies suggested that COVID-19 can potentially lead to cancer progression through multiple mechanisms. This study proposes that hesperetin not only can be used as an anti-COVID-19 agent but also can reduce the risk of multiple cancer progression by suppressing several intracellular signaling pathways in cancer patients with COVID-19. Therefore, in this review, we attempted to provide evidence demonstrating anti-COVID-19/cancer properties of hesperetin with several mechanisms.

Possible role of autophagy induced by COVID-19 in cancer progression, chemo-resistance, and tumor recurrence.

COVID-19 infection is a serious threat to patients with primary diseases, especially multiple cancers. Studies suggest that cancer patients are one of the most susceptible populations to experience severe COVID-19 and death. In addition, a number of studies suggest various mechanisms for SARS-CoV-2 in cancer progression. In this study, we discussed the role of SARS-CoV-2 in the induction of autophagy and we hypothesized that autophagy induced by COVID-19 not only can contribute to viral replication but also potentially can lead to cancer progression, chemo-resistance, and tumor recurrence in multiple cancer patients. Therefore, targeting autophagy-related signaling pathways and cellular and molecular processes could be a potentially promising therapeutic approach for cancer patients with COVID-19. Hence, this study can shed light on a new window on the management of such patients. However, more investigations in the future are required to understand other pathological effects of COVID-19 infection on cancer patients to provide new therapeutic strategies to combat these complications in these patients.
