Abstract

Since its first report in 1994, understanding of the nuclear factor erythroid 2-related factor 2 (Nrf2) has continued to grow. Initially recognized for its role in cellular response to oxidative stress, Nrf2 is now known to be involved in a variety of regulatory process, including metabolic regulation, autophagy, protein homeostasis (proteostasis), and mitochondrial biogenesis. The expression of Nrf2 target genes is highly dependent on stimulus activation and interactions with transcription factors, activators, and repressors. Nrf2 activation serves as a defense mechanism under physiological conditions, but in the context of cancer, it can trigger the development of cancer cells due to its complex roles. Nrf2 is strongly associated with the onset and development of many diseases, including those caused by metabolic disorders and inflammation. Understanding Nrf2's diverse functions offers valuable insights into disease pathogenesis and potential therapeutic approaches. This review explores the pleiotropic role of Nrf2 regulation.

Abstract

Autofagi adalah proses kompleks yang masih perlu diteliti lebih dalam. Proses ini ditandai dengan adanya pembentukan membran oleh peran protein spesifik yang disebut LC3, yang memainkan peran penting dalam mekanisme autofagi. Autofagi adalah bagian penting dari proses metabolisme, karena melibatkan pergerakan organel dari limbah ke autofagosom. Proses ini difasilitasi oleh adanya fagofor dan isolasi membran, yang penting untuk pembentukan autofagosom. Autofagosom kemudian membentuk struktur kompleks dengan lisosom, yang kemudian diubah menjadi autolisosom dan bahan yang terdegradasi. Secara umum juga dikenal dengan makroautofagi namundapat ditemukan jenis lain seperti xenofagi, chaperon-mediated autofagi. Merupakan proses penting dalam menjaga keseimbangan organ-organ internal tubuh, Autofagi juga terlibat dalam pengaturan berbagai proses fisiologis, seperti sekresi insulin, pengaturan gula darah, dan respons imun. Aging mulai dihubungkan dengan autofagi dan masih memiliki banyak ruang yang perlu didalami. Memiliki peran penting dalam aging, kehamilan dan kasus kehamilan lain seperti hambatan pertumbuhan janin, kelahiran preterm, dan Diabetes Gestasional yang banyak ditemukan pada Wanita dengan usia lebih tinggi. Mulai banyak penelitian yang menghubungkan autofagi dengan bertambahnya usia. Hasil Penelitian sebelumnya menunjukkan hubungan erat sehingga mendorong penelitian lebih lanjut untuk menjelaskan fungsi Autofagi pada aging.

Abstract

Cytoglobin (Cygb) is a new member of the globin protein family, following the discovery of other globin proteins such as hemoglobin (Hb), myoglobin (Mb), and neuroglobin (Ngb). In 2001, Kawada et al. identified Cygb in hepatic stellate cells (HSCs) that play an important role in the repair of damaged liver cell tissue, hence the name stellate cell activation-associated protein (STAP). Cygb has a more universal role than Hb, Mb, and Ngb, and is expressed throughout mammalian tissues. Cygb is a globin with 6 coordination bonds (hexacoordinate globin). Cygb has been shown to play an important role in the normal cell respiratory chain, including oxygen storage, destruction of reactive oxygen species (ROS), terminal oxidase activity, regulation of fibrogenesis, and regulation of apoptosis. The role of Cygb in the respiratory process has been studied because it is associated with the globin family, and because of the upregulation of Cygb during hypoxia, but its specific role has not been elaborated. Recent research reports that Cygb has several implications for cancer. In most cancer cells, Cygb expression is upregulated by hypermethylation, suggesting epigenetic control. In cancer cells, downregulation of Cygb occurs which indicates a possible role as a tumor suppressor gene. In some malignancies, on the contrary, Cygb upregulation may be associated with resistance to hypoxia which indicates Cygb has two sides or Janus faces related to its role in cancer cells.

Abstract

Background: Caesarean scar endometriosis is a rare form of extra pelvic endometriosis that often presents with nonspecific symptoms, leading to diagnostic challenges. Case Presentation: We report the case of a 41-year-old woman who presented with a painful subcutaneous mass at the site of a previous caesarean section, noted eight months post-surgery. MRI imaging revealed a mass suggestive of cutaneous endometriosis, and wide excision was performed. Histopathological analysis confirmed the diagnosis with identification of endometrial glands and stroma within the cutaneous tissue. Discussion: Caesarean scar endometriosis is often associated with Pfannenstiel incisions, with a latency period of symptom onset averaging over two years. While imaging such as MRI is useful for preoperative assessment, surgical excision remains the definitive treatment. Recurrence is uncommon but can occur. Iatrogenic seeding of endometrial cells during surgery is a likely etiological factor, highlighting the importance of proper surgical technique and wound cleaning. Conclusion: Although rare, cutaneous endometriosis should be considered in women presenting with cyclical pain and masses at surgical scars post-caesarean. Early recognition and surgical intervention are key to effective management and prevention of recurrence.Keywords: Cutaneus Endometriosis; Caesarean Scar; Abdominal wall mass.
