SK-OV-3

SK-OV-3 is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SK-OV-3 rather than just read about it. In short: SK-OV-3 (also known as SKOV-3; SK.OV.3; SKOV3; Skov3 and SKO3) is an ovarian cancer cell line derived from the ascites of a 64-year-old Caucasian female with an ovarian serous cystadenocarcinoma. The SK-OV-3 cell line is also hypodiploid, with a modal number of chromosomes of 43 (range 42-45), occurring in 63.3% of cells.

Key takeaways

  • SK-OV-3 belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect SK-OV-3 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of SK-OV-3 from memory before moving on to harder problems.

Reference excerpt

SK-OV-3 (also known as SKOV-3; SK.OV.3; SKOV3; Skov3 and SKO3) is an ovarian cancer cell line derived from the ascites of a 64-year-old Caucasian female with an ovarian serous cystadenocarcinoma. The SK-OV-3 cell line is also hypodiploid, with a modal number of chromosomes of 43 (range 42-45), occurring in 63.3% of cells. SK-OV-3 are positive for many of the antigens used to identify cancers of epithelial origin in clinical practice, including vimentin (VIM), high molecular weight cytokeratin (HMWK), low molecular weight cytokeratin (LMWK), epithelial membrane antigen (EMA) and leucocyte common antigen (LCA).

Use in Research Early work by Fogh, J. in 1986 showed that SK-OV-3 cells do not express the MUC16 (CA125) mucin antigen (that later became the most frequently used biomarker for ovarian cancer detection) and also showed using dose-response curves that SK-OV-3 were platinum sensitive. It was subsequently shown that ectopic expression of the MUC16 C-terminal domain in SK-OV-3 cells decreases their sensitivity to cisplatin-induced apoptosis. SK-OV-3 have been shown to produce large solid tumours (>1.5 cm^3) when injected into nude mice, with tumours loosely adhering to fat in the pelvic region, intestines and/or omentum. This cell line is also part of the NCI-60 cancer cell line panel used by the National Cancer Institute.

Worked examples

Example 1 — a first encounter with SK-OV-3

Start with the simplest possible case. Write down what SK-OV-3 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SK-OV-3 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SK-OV-3 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SK-OV-3

In research
SK-OV-3 appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses SK-OV-3 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
SK-OV-3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cancer cell lines, Human cell lines, Ovarian cancer cell line, so understanding it makes those chapters shorter.
In everyday life
Look for SK-OV-3 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SK-OV-3 in simple terms?

SK-OV-3 (also known as SKOV-3; SK.OV.3; SKOV3; Skov3 and SKO3) is an ovarian cancer cell line derived from the ascites of a 64-year-old Caucasian female with an ovarian serous cystadenocarcinoma. The SK-OV-3 cell line is also hypodiploid, with a modal number of chromosomes of 43 (range 42-45), occu…

Why does SK-OV-3 matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SK-OV-3?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
