Question: Rebecca Skloot wrote a book featuring a woman whose cervical cancer cells were named what?

Context paragraphs:
Rebecca Skloot: Rebecca L. Skloot (born September 19, 1972) is a freelance science writer who specializes in science and medicine.  Her first book, "The Immortal Life of Henrietta Lacks" (2010), was one of the best-selling new books of 2010, staying on "The New York Times" Bestseller list for over 2 years and eventually reaching #1.  It was made into a movie by Oprah Winfrey, which premiered on HBO on April 22, 2017 and starred Rose Byrne as Skloot.

Suicide gene: A suicide gene, in genetics, will cause a cell to kill itself through apoptosis.  Activation of these genes can be due to many processes, but the main cellular "switch" to induce apoptosis is the p53 protein.  Stimulation or introduction (through gene therapy) of suicide genes is a potential way of treating cancer or other proliferative diseases.  Suicide genes form the basis of a strategy for making cancer cells more vulnerable, more sensitive to chemotherapy.  The approach has been to attach parts of genes expressed in cancer cells to other genes for enzymes not found in mammals that can convert a harmless substance into one that is toxic to the tumor.  Most suicide genes mediate this sensitivity by coding for viral or bacterial enzymes that convert an inactive drug into toxic antimetabolites that inhibit the synthesis of nucleic acid.  Suicide genes must be introduced into the cells in ways that ensure their uptake and expression by as many cancer cells as possible, while limiting their expression by normal cells.  Suicide gene therapy for cancer requires the vector to have the capacity to discriminate between target and non target cells, between the cancer cells and normal cells.

Warburg hypothesis: The Warburg hypothesis ( ), sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria.  The term "Warburg effect" describes the observation that cancer cells, and many cells grown in-vitro, exhibit glucose fermentation even when enough oxygen is present to properly respire.  In other words, instead of fully respiring in the presence of adequate oxygen, cancer cells ferment.  The Warburg hypothesis was that the Warburg effect was the root cause of cancer.  The current popular opinion is that cancer cells ferment glucose while keeping up the same level of respiration that was present before the process of carcinogenesis, and thus the Warburg effect would be defined as the observation that cancer cells exhibit glycolysis with lactate secretion and mitochondrial respiration even in the presence of oxygen.

Tumor antigen vaccine: According to the National Cancer Institute, a tumor antigen vaccine is a "vaccine made of cancer cells, parts of cancer cells, or pure tumor antigens (substances isolated from tumor cells)".  A tumor antigen vaccine may stimulate the body's immune system to find and kill cancer cells.  As such, tumor antigen vaccines are a type of cancer immunotherapy.

Cervical intraepithelial neoplasia: Cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is the potentially premalignant transformation and abnormal growth (dysplasia) of squamous cells on the surface of the cervix.  Cervical intraepithelial neoplasia most commonly occurs on the cervix at the squamo-columnar junction, but can also occur in vaginal walls and vulvar epthelium.  The New Bethesda System reports all gynecologic abnormalities termed "SIL" squamous intraepithelial lesions, arising from all areas of female genital tract, and anal canal of both men and women.  Like other intraepithelial neoplasias, CIN or [SIL] is not cancer, and it is usually curable.  Most cases of CIN remain stable, or are eliminated by the host's immune system without intervention.  However a small percentage of cases progress to become cervical cancer, usually cervical squamous cell carcinoma (SCC), if left untreated.  The major cause of CIN is chronic infection of the cervix with the sexually transmitted human papillomavirus (HPV), especially the high-risk HPV types 16 or 18.  Over 100 types of HPV have been identified.  About a dozen of these types appear to cause cervical dysplasia and may lead to the development of cervical cancer.  Other types cause warts.

Osteomimicry: Osteomimicry occurs when cancer cells begin to express genes normally restricted to cells present within the bone.  These genes include osteocalcin, osteopontin, bone sialoprotein, osteonectin, RANK ligand (NF-κB receptor activator) and parathyroid hormone related peptide (PTHrP).  This change in gene expression allows cancer cells to avoid detection by the immune system and establish colonies in the bone microenvironment.  Cancer cells expressing these genes secrete normal bone ECM protein products, abnormally altering the bone matrix and activity of osteoblasts and osteoclasts in the local microenvironment.

NK-92: NK-92 is a continuously growing cell line that has features and characteristics of natural killer (NK) cells that every person has circulating in the blood.  Blood NK cells and NK-92 recognize "invaders" such as viruses and fungus.  Most importantly, NK-92, like blood NK cells, can attack cancer cells as long as the tumor has not grown out of control.  NK-92 cells were isolated and characterized by the laboratory of Dr. H. Klingemann - at that time at the British Columbia Cancer Control Agency in Vancouver, Canada.  The cells came from a patient who had a NK cell lymphoma, a rare lymphoma type.  Although several other NK cell lines have been cloned, only NK-92 can be expanded to larger numbers and consistently kill tumor cells vigorously.  When NK-92 cells bind to a cancer or infected cell, they secrete "perforin" which punches holes in target cells followed by release of "granzymes" which induce "apoptosis" in the target cells.  NK-92 cells also attack cancer cells through the Fas-Fas Ligand system and are capable of producing cytokines that by themselves can kill cancer cells (such as TNF-alpha) or stimulate and expand other immune cells such as interferon.

Cervical cancer gene database: The cervical cancer database consists of data that users (researchers and clinicians)of the system can find out if a gene leads to the expression of cervical cancer.  The clinicians and researchers will also be able to collect data as it relates to genes that may differentiate into cervical cancer.  There are several forms of cervical cancer that hypermethylate ).  The CCDB provides pertinent data as to which tumor-suppressor gene silences the gene expression of cervical cancer.

The Immortal Life of Henrietta Lacks (film): The Immortal Life of Henrietta Lacks is a drama television film directed by George C. Wolfe and starring Oprah Winfrey and Rose Byrne.  It is based on the book of the same name by Rebecca Skloot and documents the story of Henrietta Lacks, who was diagnosed with cervical cancer in the 1950s, and whose cancer cells (later known as HeLa) would change the course of cancer treatment.  The film premiered on HBO on April 22, 2017.

Cervical screening: Cervical screening is the process of detecting and removing abnormal tissue or cells in the cervix before cervical cancer develops.  By aiming to detect and treat cervical neoplasia early on, cervical screening aims at secondary prevention of cervical cancer.  Several screening methods for cervical cancer are the Pap test (also known as Pap smear or conventional cytology), liquid-based cytology, the HPV DNA testing and the visual inspection with acetic acid.  Pap test and liquid-based cytology have been effective in diminishing incidence and mortality rates of cervical cancer in developed countries but not in developing countries.  Prospective screening methods that can be used in low-resource areas in the developing countries are the HPV DNA testing and the visual inspection.
