Objective: Long noncoding RNA small nucleolar RNA host gene 1 (lnc-SNHG1) is involved in leukemogenesis via mediating multiple pathways. The current study aimed to further explore its clinical roles in disease risk, clinical features, and prognosis in patients with acute myeloid leukemia (AML).
Materials and Methods: A total of 161 adult AML patients, 50 patients as a disease control (DC) group, and 50 healthy individuals as a healthy control (HC) group were enrolled and bone marrow mononuclear cells were collected. Subsequently, reverse transcriptionquantitative polymerase chain reaction (RT-qPCR) was performed to measure lnc-SNHG1 expression.
Results: Lnc-SNHG1 expression was higher in AML patients than in the DC and HC groups (both p<0.001), with good value in distinguishing AML patients from DC and HC individuals (area under the curve of 0.726 and 0.884, respectively). Moreover, lnc-SNHG1 expression was positively associated with white blood cell (WBC) count (p=0.008) but was not correlated with other clinical features such as cytogenetics, molecular genetics, and risk stratification (all p>0.05). Lnc-SNHG1 expression was also associated with a lower complete remission (CR) rate (p=0.001). Patients with lnc-SNHG1 expression in the fourth quantile had the worst CR rates compared to patients with lnc-SNHG1 expressions in the first, second, and third quantiles (all p<0.05). Furthermore, lnc-SNHG1 expression was correlated with unsatisfactory event-free survival (p<0.001) and overall survival (p=0.002), which were worst in patients with lnc-SNHG1 expression in the fourth quantile compared to patients with lnc-SNHG1 expressions in the first, second, and third quantiles (all p<0.05).
Conclusion: Lnc-SNHG1 overexpression is associated with elevated WBC count, poor induction treatment response, and poor survival profile in cases of AML and it may serve as a potential indicator for AML.

Yetişkin Akut Myeloid Lösemide lnc-SNHG1 Geni Aşırı İfade Edilir ve Artan Beyaz Kan Hücresi Sayısı, Zayıf İndüksiyon Tedavi Yanıtı ve Kötü Sağkalım Profili ile İlişkilidir

Amaç: Uzun kodlamayan RNA küçük nükleolar RNA konak gen 1 (lnc-SNHG1), çoklu yolaklara aracılık ederek lökomogenezde yer alır. Mevcut çalışma, akut myeloid lösemili (AML) hastalarda bu genin hastalık riski, klinik özellikler ve prognozdaki klinik rolünü daha ayrıntılı araştırmayı amaçlamaktadır.
Gereç ve Yöntem: Toplam 161 yetişkin AML hastası ile birlikte, 50 hasta hastalıklı kontrol grubu (HK) olarak, 50 sağlıklı birey sağlıklı kontrol (SK) grubu olarak çalışmaya alındı ve kemik iliği mononükleer hücreleri toplandı. Ardından, lnc-SNHG1 ifadesini ölçmek için ters transkripsiyon-kantitatif polimeraz zincir reaksiyonu (RT-qPCR) yapıldı.
Bulgular: Lnc-SNHG1 ifadesi AML hastalarında HK ve SK gruplarına göre daha yüksekti (her ikisi de p<0,001) ve AML hastalarını HK ve SK bireylerden ayırt etmede iyi bir değere sahipti (sırasıyla eğrinin altındaki alan 0,726 ve 0,884). Ayrıca, lnc-SNHG1 ifadesi, beyaz kan hücresi (WBC) sayısı ile pozitif olarak ilişkiliydi (p=0,008) ancak sitogenetik, moleküler genetik ve risk sınıflandırması gibi diğer klinik özelliklerle korele değildi (tümü p>0,05). Lnc-SNHG1 ifadesi ayrıca daha düşük bir tam remisyon (TR) oranı ile ilişkilendirilmiştir (p=0,001). Dördüncü çeyrekte lnc-SNHG1 ekspresyonu olan hastalar, birinci, ikinci ve üçüncü çeyrekte lnc-SNHG1 ifadesi olan hastalara kıyasla en kötü TR oranlarına sahipti (tümü p<0,05). Ayrıca, lnc-SNHG1 ekspresyonu, olaysız sağkalım (p<0,001) ve genel sağkalım (p=0,002) oranlarında tatmin edici olmayan sonuçlarla ilişkili bulundu.
Sonuç: Lnc-SNHG1 aşırı ekspresyonu, AML olgularında yüksek WBC sayısı, zayıf indüksiyon tedavisi yanıtı ve kötü sağkalım profili ile ilişkilidir ve AML için potansiyel bir gösterge görevi görebilir.
