    Applications
    PROM1, also known as Prominin-1, is a gene that has been studied in various medical contexts. In one study, PROM1 was found to be associated with pigment epithelial detachment (PED) in age-related macular degeneration (AMD). The researchers established a polygenic risk score using PROM1 and other non-coding variants to predict the risk of PED occurrence. Another study focused on PROM1 in KMT2A-rearranged acute lymphoblastic leukemia (ALL). The researchers found that acquired resistance to a DOT1L inhibitor in pediatric KMT2A::AFF1+ B-ALL cells led to a loss of PROM1 expression, indicating the adaptive potential of these leukemia cells. Additionally, PROM1 was investigated in high-grade serous ovarian cancer (HGSOC). The study found that PROM1 mRNA and protein levels were associated with clinical outcomes, such as chemotherapy response, overall survival, and disease-free survival. Finally, PROM1 was studied in mouse retinal pigment epithelial (RPE) cells. Loss of Prom1 function impaired autophagy and promoted epithelial-mesenchymal transition (EMT) in these cells, suggesting its role in RPE homeostasis and retinal degenerative diseases.

    Published Data

    Fig.1 A notable decrease in colony-forming ability was observed as a result of PROM1 knockdown using either shRNA, without any such reduction occurring in doxycycline-treated control SEM cells, wherein the number of colonies was reduced to less than 50% of the uninduced control.

    The percentage of colonies formed in the presence of 0.5 µg/ml doxycycline (+Dox) was measured in control and PROM1 shRNA 1 and 2 SEM cell lines, and compared with the uninduced control (Con = −Dox). The error bars depict the standard deviation of three (control) or four (shRNA) biological replicates, with **p < 0.01 indicating statistical significance, while ns denotes no significant difference.

    Wąsowska, Anna, et al. "Polygenic Risk Score and Rare Variant Burden Identified by Targeted Sequencing in a Group of Patients with Pigment Epithelial Detachment in Age-Related Macular Degeneration." Genes 14.9 (2023): 1707.
    A group of researchers analyzed the results of ophthalmic imaging examinations from 334 patients to identify a specific subgroup of patients with pigment epithelial detachment (PED). Among the patients, a subgroup of 47 individuals with PED was identified. These patients were compared to two other groups - those with age-related macular degeneration without PED and healthy individuals. A polygenic risk score was established, explaining 16.3% of the disease variation. The most accurate predictive model included six non-coding variants: rs760306 (AMD), rs2230199 (CFH), rs1061170 (CFH), rs3753394 (C2), rs800292 (C3), and rs2230201 (C3).

    Schneider, Pauline. et al. "Modelling acquired resistance to DOT1L inhibition exhibits the adaptive potential of KMT2A-rearranged acute lymphoblastic leukemia." Experimental hematology & oncology, 2023.
    In KMT2A-rearranged acute lymphoblastic leukemia (ALL), an aggressive malignancy, the oncogenic KMT2A-fusion proteins inappropriately recruit DOT1L to promote leukemogenesis, highlighting DOT1L as a potential therapeutic target. However, the first-in-class DOT1L inhibitor pinometostat eventually becomes ineffective in treating this type of leukemia. To gain insight into this phenomenon, a team established acquired resistance to pinometostat in pediatric KMT2A::AFF1-rearranged ALL cells.
