Staining of NFIL3 (green) in nuclear bodies with DNA (blue) and microtubules (red) in A-431 cells. Many human genes follow a so called circadian clock and research has shown that some of those genes themselves follow the seasons (Dopico et al. 2015). When winter is coming, you sense it and your genes know it too. Expression of one of those genes, NFIL3, peaks during December until February and has its lowest expression during the summer months.
NFIL3 is a transcriptional regulator involved in regulation of immune processes. Like many other transcription regulators it localizes to nuclear bodies as seen on the Cell Atlas images and binds to specific DNA motifs...Read more
Next in our series of articles on cancer is Pancreatic cancer, a relatively rare cancer associated with very poor prognosis. The vast majority of tumors originate from ductal cells and a small fraction are endocrine tumors. Over 80% of pancreatic cancers develop at ages above 60 years and most tumors are detected at late stages of the disease when the cancer has spread beyond the pancreas.
There is a great need for biomarkers to facilitate early detection and help establishment of diagnosis. Smoking, obesity, physical inactivity and long-lasting inflammation in the pancreas are some of the factors that lead to an increased risk of pancreatic cancer...Read more

Previously we have highlighted proteins expressed in the human neural retina. This week's article emphasizes the cellular structure and molecular dynamics of the lens.
The main function of the lens is to focus light on the retina. The passage of light through the cornea, lens and vitreous all the way to the retinal layer of the eye is only possible due to transparency of the tissue. Although the lens is very protein-rich, light absorption and light scattering in the lens is minimal.
The lens comprises non-diving lens cells which are mainly composed of ordered proteins called crystallins...Read more

The mammary gland develops from the epidermis and is mainly composed of branched columnar and cuboidal epithelial cells that form distinct lobes...Read more
The JAK – or Janus kinases, are intracellular proteins that transduce signals from cytokine receptors via the JAK-STAT pathway. More specifically the JAK family phosphorylates the receptor and thus activates downstream proteins, including transcription factors called STATs (Signal Transducers and Activators of Transcription). These transcription factors then migrate to the nucleus where they regulate transcription of many genes with diverse function, including cell growth, development and differentiation...Read more
Melanoma is a common form of cancer in the skin and among skin cancers it is the most deadly form. Melanoma originates from cells of melanocytic origin and most typically begins as a small intraepidermal tumor (melanoma in situ). As the tumor continues to grow and progress, tumor cells invade the epidermis and eventually spread to regional lymph nodes and subsequently via hematogenic spread to distant organs. Tumor thickness of the primary tumor is the most important determining prognostic factor and thus is early discovery of key importance for survival.
The cancer image of the month shows skin with growth of a cutaneous melanoma...Read more

This blog post is in honor of World Malaria Day
When infected mosquitos bite people they transmit parasites that causes malaria. Symptoms of malaria include fever and flu-like illness, and if left untreated the illness will cause anemia (loss of red blood cells) and eventually death.
According to WHO, malaria caused 429 000 deaths in 2015, and 70% of the deaths are children under the age of 5. Luckily, mortality rates are falling, and since 2010 the mortality has dropped with almost 1/3. Early diagnosis and treatment of malaria reduces deaths and prevents transmission. There are antimalaria drugs available, but currently, there is no availabe malaria vaccine...Read more
Mitochondria harbors an own genome that renders key proteins involved in production of energy through oxidation of various substrates. Majority of the disorders associated with mitochondrial function are caused by impaired expression of the proteins encoded in the mitochondrial genome. One of these proteins is the translational activator of cytochrome c oxidase 1 (TACO1).
Experimental results reveal that TACO1 is expressed in all tissues within the human body. The protein is detected mainly in the cytoplasm and more precise inside mitochondria. Explore expression and subcellular localization of TACO1 in the Cell Atlas...Read more
Within the Human Protein Atlas project, antibodies are used to study the localization of protein in human tissues and cells.
